[0008] An electric motor with an upstream frequency converter is known from DE 298 80 014 U1.

[0009] An electric motor with electronic control is known from EP 1 246 345 A1.

[0010] WO 00 / 05 806 A1 discloses a method for an electrical machine.

[0011] An inverter motor is known from DE 101 09 797 A1.

[0012] The invention is therefore based on the object of developing a device and a method, whereby the costs of operation, including commissioning, are to be reduced and errors are to be avoided.

[0013] According to the invention, the object is achieved in the system according to the features specified in claim 1, in the drive according to the features specified in claim 10 and in the method according to the features specified in claim 11.

[0014] Key features of the system according to the invention are that it comprises at least one electric motor and an L / A unit for reading a data carrier, wherein the electric motor has a first interface for receiving the data carrier. Advantageously, the data carrier can be written with the motor data and, if necessary, additional data during motor production. This makes it readable during commissioning in the customer's machine or system, where the data is then available for commissioning, for example, a converter or for commissioning a system including a communications system.

[0015] In an advantageous embodiment, the electric motor includes a brake. This is advantageous because the data from the brake, not just the motor, can also be stored on the data storage device.

[0016] According to the invention, the first interface is a mechanical holding device for the data storage device. This is advantageous because it allows for simple and cost-effective implementation.

[0017] According to the invention, the first interface is designed electromechanically, in particular for mechanical connection, such as holding, and additionally for electronic data transmission to the L / A unit. This is advantageous in that additional data can be transmitted, in particular via a wired connection to an L / A unit.

[0018] According to the invention, the first interface is provided in or on the terminal box of the electric motor. This is advantageous because the data storage device can be mounted in a protected manner within the box or easily and quickly accessible on the outside of the box.

[0019] According to the invention, a second interface is provided on the L / A unit for receiving the data carrier, in particular for selective reception. Advantageously, the second interface can be designed to be compatible with the first interface in such a way that the data carrier can be switched from the first to the second interface.

[0020] In an advantageous embodiment, the second interface is electromechanical, particularly for mechanical connection, such as holding, and also for electronic data transmission to the L / A unit. This is advantageous because, after plugging the data carrier into the second interface, data transmission from the data carrier to the L / A unit and from there to downstream devices or to a communications system is possible.

[0021] In an advantageous embodiment, the L / A unit is provided in the cover of a terminal box of the electric motor. This is advantageous because when the cover, i.e., an upper part, is placed on the lower part of the terminal box, the L / A unit can also be brought so close to or into contact with the data carrier that data transmission is enabled.

[0022] In an advantageous embodiment, the L / A unit is a housing on or combined with a device and / or integrated. This is advantageous because the data can be processed by the device. Furthermore, the housing-forming function for the unit can be performed by the device's housing, as can the power supply.

[0023] In an advantageous embodiment, the device is a converter, in particular a converter for supplying the electric motor. Alternatively, the device is a soft starter, in particular for soft starting the electric motor. In another alternative, the device is a motor switch, in particular for switching the electric motor. The advantage here is that the data on the data carrier is used to parameterize these devices and / or can be transmitted to other fieldbus devices via the fieldbus connection of these devices.

[0024] Instead of the fieldbus, another bus or communication system can also be advantageously used. The data includes not only the parameters required for parameterizing the devices, but also order-related, machine-related, or plant-related data. The latter are used by the participants, for example, to trigger plausibility checks or schedule-dependent processes such as maintenance warnings and the like.

[0025] In an advantageous embodiment, the L / A unit is connected to a communications system, in particular a bus system such as a fieldbus or the like, for data exchange. This advantageously allows the data to be transmitted to other bus devices, such as central computers or drive systems with a bus connection.

[0026] In an advantageous embodiment, the device can be connected to the electric motor, in particular to its connection devices in the terminal box, by means of at least one connector. The advantage here is that the connection can be carried out quickly and safely.

[0027] In an advantageous embodiment, the device housing includes at least one heat sink. This allows the device to contain power electronics despite its proximity to the motor. In particular, a thermal barrier is provided toward the motor.

[0028] In an advantageous embodiment, the device is connected to a communications system, in particular a bus system such as a fieldbus or the like, for data exchange. This is advantageous because the data can be transmitted to other bus participants, whereby the data may differ from the data required for parameterizing the device.

[0029] In an advantageous design, the device is installed separately from the electric motor, particularly in the system's control cabinet or in the system's field. This is advantageous because, during commissioning, the operator only needs to remove the data carrier from the motor and insert it into the device's interface. This makes commissioning easy.

[0030] In an advantageous embodiment, the data carrier can be read by the read / write unit either contactlessly or via a wired connection. The advantage is that contactless reading eliminates the need for connection devices. With wired reading, interference signals can be reduced.

[0031] In an advantageous embodiment, the data carrier can be read mechanically by the read / write unit, particularly as a punched card, optically, inductively, magnetically, or electrically. The advantage here is that a simple mechanical solution that ensures long-term stability can be implemented. Otherwise, contactless variants, such as optical, inductive, or magnetic, are feasible, with advantages known to those skilled in the art.

[0032] In an advantageous embodiment, the data storage device comprises a memory for storing parameters that can be used to commission the converter, such as, in particular, electrical and mechanical rated data of the electric motor, rated data of the brake, and / or the date of manufacture of the electric motor. It is advantageous that various data can be stored on the data storage device.

[0033] In another advantageous embodiment, the L / A unit is not connected to the electric motor, in particular neither mechanically nor electronically. This is advantageous because the operator removes the data carrier from the motor when starting up the motor and then connects it to the unit for data transmission. This then forwards the data to a connected communications system.

[0034] Key features of the drive include the aforementioned system, with commissioning of the drive being provided by reading the data carrier. A key advantage is that commissioning is quick and easy. In particular, the operator does not need in-depth knowledge of parameters and is still able to parameterize the drive.

[0035] Essential features of the process for manufacturing and / or commissioning a drive are that - an electric motor is manufactured, - a data carrier is written with data, in particular the type plate data of the electric motor, - the data carrier is mechanically connected to the electric motor, - when commissioning a machine or system, an L / A unit is connected to the data carrier for reading the data, - the data is transmitted to a communication system or to an inverter that supplies the electric motor.

[0036] The advantage is that commissioning is very easy to carry out, meaning the operator does not require extensive training and the probability of errors occurring during commissioning can be reduced.

[0037] In particular, to commission the data carrier, it is disconnected from the electric motor and connected to the L / A unit. The advantage of this is that the operator does not have to enter any parameters, thus eliminating the possibility of errors. The only thing that needs to be done is to plug in the data carrier.

[0038] Alternatively, the L / A unit can be plugged into a connector interface of the electric motor for commissioning. The advantage of this is that the connection and thus commissioning are particularly quick and easy.

[0039] Further advantages arise from the subclaims.

[0040] The invention will now be explained in more detail with the aid of illustrations: In the Fig. 1a schematically shows a system according to the invention with an electric motor 3 as the drive component, wherein a data storage device 1 is provided at an electromechanical interface 10 in the terminal box 2. The interface 10 comprises plug-in connections. Thus, the data storage device 1 can be connected in a plug-in manner, i.e., quickly and easily. The terminal box 2 is mounted on the stator housing and forms a housing-forming part for the connection devices, which are provided for connecting to the lines supplying the electric motor 3. The removable cover of the terminal box can be designed as a simple cast part or with integrated electronics, such as converter electronics, soft-start electronics, or motor switch electronics. In one of the exemplary embodiments according to the invention, the respective associated power electronics are cooled via cooling devices on the cover.

[0041] In further embodiments according to the invention, the interface is only a mechanical interface, for example designed as a holding device for holding the data carrier 1.

[0042] In the Fig. Figure 1b shows the reading and evaluation unit 4, also referred to here as the read / write unit. This unit includes the electromechanical interface 11, into which the data carrier 1 removed from the terminal box is plugged, thus providing a mechanical and electronic connection. This interface 11 preferably includes corresponding plug connections like the interface 10, so that the data carrier can be plugged in quickly and easily.

[0043] In the system according to the invention according to Fig. 2a, the data carrier is provided via the interface 10 on the terminal box 2 of the electric motor 3. The reading and evaluation unit (R / A unit) A is mounted on or on the terminal box and is electronically connected to a communication system K for data transmission.

[0044] For example, in another system according to the invention, again according to Fig. 2a, it is advantageous to mount the L / A unit inside a cover, i.e., a housing part. This way, the L / A unit is connected when the cover is placed on its terminal box, and the data carrier is readable. Thus, once the drive is fully installed and mounted in the system, the data on the data carrier is available to the communication system K. Thus, the necessary connection of the cover to the terminal box base also ensures that the data carrier is readable.

[0045] The data carrier can, for example, contain nameplate information of the motor and also of the sensor connected to it.

[0046] In the system according to the invention according to Fig. 2b, instead of the cover, a converter FU can be plugged onto the terminal box base and connected to supply the electric motor 3. The converter FU is integrated with the L / A unit A and can therefore immediately recognize the type of motor 3 and the associated parameters. The parameters of the converter FU are then defined accordingly and can also be transferred to the communication system K. Commissioning is thus made much faster. Fig. 2b is a converter motor. Such drives are very compact, as the motor 3 and converter FU form a single unit.

[0047] In the system according to the invention according to Fig. 2c, the converter (FU) is mounted separately from motor 3, for example, in the control cabinet of a system. The converter (FU) is connected to motor 3 via power cables so that the converter (FU) can supply and control motor 3. It is mechanically protected and secured in the control cabinet.

[0048] Therefore, the requirements for the protection class are not as high as in the example according to Fig. 2b. The data carrier 1 is located on the inverter FU and is connected there via interface 12. The inverter FU is in turn connected to the communication system K for data exchange, preferably via fieldbus or another bus system. Fig. 2c is disk 1 from the

[0049] Interface 10 of the terminal box and plugged into interface 12 of the inverter FU. This allows parameters to be stored on data carrier 1 during production and delivered connected to the motor. During commissioning, only the data carrier needs to be plugged into the inverter FU and the motor-related parameters are then known. However, Order-related data can be stored on the data storage medium. This order-related data can also include application-related data, i.e., data that is characteristic of the system or machine and must be taken into account by the frequency converter (FU) when controlling and regulating the drive comprising the electric motor 3.

[0050] The data carrier can be removed from the interface 10, for example, using a holding device. This allows the data carrier to be detached from the motor and inserted into the mounting device of the motor-independent L / A unit. The data carrier can also contain all the commissioning parameters for the inverter (FU).

[0051] The data storage information can be implemented mechanically, magnetically, or electrically. Accordingly, the data storage medium may comprise, for example, a punched card, a magnetic stripe, or a semiconductor chip.

[0052] The evaluation of the data carrier information can be performed contactlessly, such as optically, magnetically, or inductively. Data carriers implemented as RFID tags can also be used. Transponder technology or surface acoustic wave (SAW) technology can also be used. Alternatively, wired data transmission is also possible.

[0053] In further embodiments according to the invention, data from the data carrier is transmitted not only to the converter, but also to a higher-level communication system. This also applies to data that is not related to the operation of the converter and does not contain any parameters of the converter or the components running there.

[0054] Programs are. Higher-level systems can process the data. For example, the motor's manufacturing date cannot be used by the inverter. However, the central controller can use this date to calculate maintenance dates or trigger other time-dependent actions, such as replacing the motor, adjusting the brake, or the like.
