Description
Technical Field
[0001] The present invention relates to the technical field of performance testing, and in particular to a performance testing system and a testing method for a low-energy-consumption, short-wheelbase, high-performance servo motor. Background Art
[0002] A servo motor is an engine that controls the operation of mechanical components in a servo system. It is an auxiliary motor indirect speed change device. The servo motor can control speed and position accuracy very accurately, and can convert voltage signals into torque and speed to drive the control object. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an actuator and has the characteristics of small electromechanical time constant, high linearity, and starting voltage. It can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft. It is divided into two categories: DC and AC servo motors. Its main characteristics are that there is no self-rotation when the signal voltage is zero, and the speed decreases uniformly with the increase of torque.
[0003] According to the patent publication number CN211577355U, a motor performance test device under different environments includes a sealed box, the right end of the sealed box is fixedly connected to a device box, the front end of the sealed box is movably connected to a sliding door, and the upper end of the motor base is fixedly connected to the motor to be tested. The motor performance test device under different environments can detect its noise, vibration, heat dissipation, and load-bearing conditions. The device is easy to operate and has a simple structure, which greatly reduces the situation where some unqualified motor products flow into the market. However, the motor performance test device under different environments has the following shortcomings:
[0004] (1) The motor position is controlled by T-slots, which makes the motor easy to slide back and forth, resulting in poor fixing effect and low safety during testing;
[0005] (2) If direct clamping is used, the servo motor surface is uneven, which may cause shaking during the clamping process, making it difficult to achieve multi-point extrusion.
[0006] (3) When the motor is under high load, the heat on the motor surface is naturally dissipated, affecting the performance of the motor and thus the service life of the motor.
[0007] Therefore, the present invention proposes a performance testing system and a testing method for a low-energy-consumption, short-wheelbase, high-performance servo motor to solve the above-mentioned problems. Summary of the invention
