Problems solved by technology

[0003] The existing motor control is mainly used to start or shut down the motor as a whole, and it is impossible to control the rotation direction of each motor separately. Therefore, it is difficult to meet the user's demand for different rotation directions of each motor when operating multiple motors; at the same time , the existing motor control device has no division of control levels. Therefore, when the master control staff outputs the master control signal to control the motor as a whole through the master control switch, the signals of other control switches in the motor control device will affect the master control. The execution of the signal reduces the effectiveness of the execution of the master control signal and creates obstacles for the master control staff to control the operation of the motor as a whole

Embodiment Construction

[0021] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0022] Such as figure 1 As shown, the present invention is a controller for controlling a motor 1, the controller includes a contact module 2, a power module 3 connected to an AC power source (not shown in the figure) to receive AC power and deliver it to the motor 1, and a power module 3 with Main control module 4 and sub-control module 5 for controlling the rotation direction of motor 1; Connect to motor 1.

[0023] Specifically, the contact module 2 includes contactors K1, K2; the contactor K1 includes normally open terminals K11, K13, K15, K17, normally closed terminals K12, K14, K16, K18, and an electromagnetic coil KM1; the two ends of the electroma...

Abstract

The invention discloses a controller for controlling motors. The controller comprises a contact module, a power supply module which is connected with power supply for receiving AC power and transmitting the AC power to the motors, a master control module and a sub control module which are used for controlling a motor rotation direction. The power supply module is connected with the contact module and the motor. The master control module is connected with the contact module. The sub control module is connected with the contact module and the motor. The controller is advantageous in that the master control module is used as an intelligent signal receiving end for realizing functions such as integral control and emergency control to the motor; and the sub control module is used for controlling each motor for satisfying a requirement for different rotating directions of each motor; a master control signal is used as a highest control grade; a sub control signal is used as a secondary control grade so that the user can directly perform integral control on the motor through the master control module and disenables the sub control signal, thereby preventing interference of the sub control signal to execution of the master control signal, and improving execution reliability of the master control signal.

Description

technical field [0001] The invention relates to the field of motor control, in particular to a controller. Background technique [0002] Motor control refers to the control of starting, accelerating, running, decelerating and stopping the motor. There are different requirements and purposes according to the type of motor and the application occasion of the motor. Achieve the purpose of fast start, fast response, high efficiency, high torque output and high overload capacity of the motor through motor control; [0003] The existing motor control is mainly used to start or shut down the motor as a whole, and it is impossible to control the rotation direction of each motor separately. Therefore, it is difficult to meet the user's demand for different rotation directions of each motor when operating multiple motors; at the same time , the existing motor control device has no division of control levels. Therefore, when the master control staff outputs the master control signal ...
