Testing of electric motors with motor housing for reception of stator and motor shaft - detecting deflection of support when electric motor is switched on and determining deflection speed and acceleration

摘要

The electric motor (1) is switched on and the resulting deflection of the supporting device (4,8) or of the part held by it is detected from the reaction moment of the electric motor. The motor housing is held by the supporting device. In addition to the deflection direction, also the deflection speed and/or the acceleration is determined. The motor housing is held in the supporting device (4,8). The supporting device is located rotationally in a frame, which is connected with it across resilient mountings (7,7a). ADVANTAGE - Direction of rotation of motor can be identified, and connection faults occurring during assembly can be established.
