A torque motor resistance torque testing system

Abstract

The invention relates to a motor testing device and particularly relates to a torque motor resistance moment testing system. The system comprises a resistance moment testing bench which comprises a tested motor mounting seat and a load device mounting seat which are oppositely arranged. The load device mounting seat is fixedly assembled with a torque loading device and an angle sensor. The rotor of the angle sensor is connected with the torque loading device which is also connected with a torque sensor. The torque sensor is provided with an input end which is connected with the torque loading device and a measuring end used for connecting the corresponding measured motor. According to the torque motor resistance moment testing system, due to the existence of the torque loading device and the angle sensor, when in use, the system can be directly combined with a motor measuring system with a computer as a main body to carry out resistance moment testing on a torque motor, and by using the high efficiency and high precision characteristics of the motor measuring system with the computer as the main body, the resistance torque testing precision of the torque motor is improved.

Description

technical field [0001] The invention relates to a motor testing device, in particular to a torque motor resistance torque testing system. Background technique [0002] Torque motors are divided into DC torque motors, AC torque motors and brushless DC torque motors. They are designed in combination with servo motors and drive motors. They are special motors with soft mechanical characteristics and wide speed range. The shaft of this motor does not output power with constant power but with constant torque. It has the characteristics of low speed, high torque, strong overload capacity, fast response, good characteristic linearity, and small torque fluctuation. [0003] In the process of use, in order to fully meet the requirements of the dynamic performance of the control system and achieve high-precision control, it is necessary to accurately grasp the parameters of the motor. Torque ripple is an important indicator of torque motors. Usually the requirement should be less th...

However, no one has applied the computer-based motor test system to the resistance torque test of the torque motor

[0007] At present, the weight-torque plate test method is widely used in the resistance torque test of torque motors, and manual measurement and counting is used, which is inefficient and the accuracy cannot meet the requirements, and the relationship between the rotation angle and the resistance torque cannot be accurately measured.
