The invention discloses a device for calibrating the output torque of a DC motor. An AC servo motor, a planetary reducer, a conductive slip ring, a torque sensor and a DC motor to be calibrated are assembled on a calibration platform, and the central axis coincides. The planetary reducer and the AC servo motor connected. One end of the conductive slip ring is connected to the output signal line of the torque sensor, and the other end is connected to the controller. The controller includes a DC motor drive current measurement module, a torque sensor voltage signal measurement 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, so as to realize the dynamic calibration of the DC motor. The invention has the advantages of simple implementation, convenient operation and high work efficiency, and can accurately calibrate the relationship between the output torque of the DC motor and the driving current, thereby improving the control efficiency of the DC motor and improving the control effect of the DC motor.
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 ...
