Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically to a rotary motor with a drive module. Background Technology

[0002] There are many types of rotating electric machines. They can be classified by function as generators and motors, by voltage type as DC motors and AC motors, and by structure as synchronous motors and asynchronous motors. Asynchronous motors can be further classified by the number of phases into three-phase asynchronous motors and single-phase asynchronous motors; and by rotor structure into squirrel-cage and wound-rotor types. Among these, the squirrel-cage three-phase asynchronous motor is the most widely used and in the largest demand among all types of electric motors due to its simple structure, ease of manufacture, low price, and reliable operation.

[0003] In order to control multiple parameters of the existing rotary motor (such as speed, voltage, current, power, etc.), users need to connect an external drive module to drive the motor in practical applications. The motor is connected to the external module through leads, which not only makes the structure complicated by the number of leads, but also wastes time and increases the workload of operators because an external drive module is required every time it is used. Utility Model Content

[0004] This invention provides a rotary motor with a drive module, which features a simplified motor structure and ease of use.

[0005] A rotary motor with a drive module includes a rotary motor body, a drive module connected to the rotary motor body, a housing, a first fastener, and a wire frame assembly for connecting external wiring. One end of the housing engages with the rear end of the rotary motor body, and the housing and the rotary motor body are fixed by the first fastener. The housing has an assembly opening. The drive module is located inside the housing and fixed to the housing. The wire frame assembly engages with the assembly opening, is connected to the drive module, and is fixed to the housing.

[0006] Furthermore, the housing includes a housing body, a connecting plate, a cover plate, and a second fastener. The housing body is hollow and has openings at both ends. One end of the housing body is engaged with the rear end of the rotary motor body. The connecting plate is located inside the housing body and is fixed to the housing body. The first fastener passes through the connecting plate and connects to the rotary motor body, thereby securing the housing and the first fastener together. The cover plate is engaged with the other end of the housing body. The second fastener passes through the cover plate and connects to the housing body, thereby securing the cover plate and the housing body together.

[0007] Furthermore, it also includes a third fastener. The drive module includes a drive module body and a first connector. The first connector is fixed to the drive module body. The third fastener passes through the cover plate and connects to the first connector to fix the drive module and the cover as one unit.

[0008] Furthermore, it also includes a fourth fastener. The wire frame assembly includes a circuit board, multiple terminals, connecting wires, and a second connector. The terminals are soldered and fixed to the circuit board. At least one terminal is connected to the drive module via the connecting wire. The second connector is fixed to the circuit board. The fourth fastener passes through the cover and connects to the second connector to fasten the cover and the wire frame assembly together.

[0009] This invention places the drive module at the end of the rotary motor body, simplifying the connection between the wires and the drive module, and making the rotary motor body and the drive module an integrated unit. Users only need to power on the drive module to drive the motor. The structure is simple, easy to use, and easy to install. Attached Figure Description
