Controller debugging device capable of simulating dynamic load loading

The invention relates to a controller debugging device capable of simulating dynamic load loading, and belongs to the field of load debugging. The device comprises a motor main shaft, a coupler, a torque sensor, an encoder, a loading disc, a loading electromagnet, a fixed bearing seat and a loading main control computer, according to the invention, a simulated dynamic load is provided for controller debugging, and the debugging of the controller is greatly facilitated. Secondly, independent air cooling equipment is provided for the motor, so that the motor can be ensured to be always in a good working environment temperature; and a liquid cooling device is provided for the loading disc, so that the loading disc cannot be heated to cause high-temperature ablation, and the whole debugging or testing process can be continuously carried out for a long time. The debugging test is shortened to one third of the original debugging test, the compressor is not damaged, and the economic cost is reduced. 本发明涉及一种可模拟动载荷加载的
