Bus-based direct-current motor and control method thereof

Abstract

The invention relates to a bus-based direct-current motor and a control method thereof. The bus-based direct-current motor comprises a power module for supplying power; the power module is connected with a master control module, an encoder module and a motor driving module. The master control module is connected with the motor driving module for controlling a motor, is connected with the encoder module for measuring speed and position, is connected with a voltage detection module for detecting voltage, is connected with an LED module for displaying various light effects, and is connected witha bus interface for inputting and transmitting power and signals; a control module of the direct-current motor is directly installed at the back of the motor, and a drive chip is cooled through a casing of the motor. The bus-based direct-current motor is easy to control, can control as much as 253 devices by sending serial-port orders, can be connected by means of three-wire cascading in a simplemanner, can be switched into a steering mode and a speed mode randomly, and has wide application scope.

Description

technical field [0001] The invention relates to the field of direct current motor control, in particular to a bus type direct current motor and a control method thereof. Background technique [0002] DC motors are widely used in industrial production and life, especially DC geared motors. Through different reduction ratios, the output torque and speed of DC motors can be matched arbitrarily. Most of the DC geared motors are driven by external drivers. The wiring of the motor with encoder is more complicated, and all motor data acquisition and drive output are processed by the external drive module. A single module may not have enough processing capacity, and multiple modules are bulky, complex wiring, poor line contact, and motor parameters. Difficulty in collecting information.

[0003] "Bus Type Intelligent Motor" applied by Yu Dehai and others from Dalian Guangyang Technology Engineering Co., Ltd., the publication number is CN101150272, and the publication date is 20080326. It proposes a bus type intelligent motor, including an integrated motor, servo driver, The encoder and radiator control the motor through the FPGA integrated system and the Ethernet bus. Although it can solve the problem of motor integration and bus intelligent control, the cost is too high and the system is complicated, so it is not suitable for small geared motors.
