Abstract
A mechanical test device for testing shell-less motor includes a test bench, test motor, a test pedestal, a lift column, a lift platform upper plate, a lift platform lower plate, a stator fixture, a rotor fixture, bearings, a connecting shaft, a torque sensor, a magnetic powder brake, a lift device, and a shaft center-unified device. The test motor is fixed on a sliding guide rail by a rotor vertical adjustment device and a special fixture for a motor stator. The motor fixture uses a triangle structure to prevent the deviation of a central axis of a motor shaft. After the stator is fixed, the coaxial installation can be realized by adjusting the rotor vertical lift and adjusting device.
