Abstract

The invention discloses a direct current motor output torque calibration device, which is characterized in that an alternating current servo motor, a planetary reducer, a conductive slip ring, a torque sensor and a direct current motor to be calibrated are assembled on a calibration platform, central axes coincide, and the planetary reducer is connected with the alternating current servo motor; one end of the conductive slip ring is connected with an output signal line of the torque sensor, and the other end is connected with a controller; and the controller comprises a direct current motor drive current measuring module, a torque sensor voltage signal measuring module, a motor drive control module and a communication module. In addition, the device can set the servo motor to rotate at a certain speed, and thus the dynamic calibration of the direct current motor is realized. The device has the advantages of simple implementation, convenient operation and high working efficiency, and can accurately calibrate the relationship between the output torque of the direct current motor and the driving current, and thus the control efficiency of the direct current motor is improved, and thecontrol effect of the direct current motor is improved.

Description

technical field [0001] The invention relates to a detection device for measuring the torque of a DC motor, in particular to a calibration device for output torque of a DC motor. Background technique [0002] A DC motor is a device that is driven by DC power and can convert or transmit electrical energy. It can be used as a power source for various mechanical components by outputting torque. The DC motor has the advantages of large starting and braking torque, easy control and good speed regulation performance, so it is widely used in devices that require high speed regulation or require a large starting torque. At present, DC motors have been widely used in many fields such as robot control, medical equipment and electric vehicles. [0003] In order to achieve effective control of a DC motor, it must first be able to accurately control its output torque, and each DC motor often has a different relationship between output torque and current. In order to realize the stable ...
