Abstract

The invention relates to the technical field of motor detection, and provides a fixing tool for a motor stalling test. The fixing tool comprises a positioning base and a clamping mechanism; the positioning base is provided with an accommodating cavity for accommodating the clamping mechanism; the clamping mechanism comprises a lead screw which is hinged to the inner wall of the containing cavity and can rotate around the central axis of the lead screw, and two clamping arm assemblies which are arranged on the lead screw in a sleeving mode and are oppositely arranged. When the lead screw rotates around the shaft clockwise, the two clamping arm assemblies move oppositely in the containing cavity so as to apply bidirectional acting force to the rotor part of the motor to achieve the locking purpose. When the lead screw rotates around the shaft anticlockwise, the two clamping arm assemblies move oppositely in the containing cavity, and therefore the rotor part is unlocked. In conclusion, the fixing tool can apply acting force to the rotor part of the motor from two opposite directions, the centering efficiency of the rotor part of the motor is improved, and meanwhile, the stability of limiting the rotor part of the motor through bidirectional stress is higher.

Description

technical field [0001] The invention relates to the technical field of motor detection, and in particular provides a fixed tool for motor stall testing. Background technique [0002] Motor stall performance is an important part of motor performance testing. Motor stall refers to a state where the motor still outputs torque at zero speed, which simulates the phenomenon that the motor cannot start or stop rotating due to excessive motor overload. The motor stall test is to measure the stall current I at the rated voltage k and stall torque value T k and the stall loss P k , At the same time, some quality problems of the motor are reflected by measuring the locked rotor characteristic curve. [0003] The working principle of the fixed tooling for the motor stall test is to fix the stator and rotor of the motor separately, overcome the torque of the motor at the rated voltage, ensure that the rotor does not rotate, simulate the stall state, and facilitate the measurement of ...
