Test just include locked rotor test this；Stall is also motor when generation mechanical breakdown, serious overload and voltage are seriously reduced
A kind of least favorable state that rotor is stopped operating completely, the main testing of electric motors breakdown torque of locked rotor test, capability of overload, temperature rise
Etc. index whether reach standard.
At present, motor rotation blockage test be Motor Production Test test one must pilot project, former locked rotor test method be by
The motor of energization is carried out under not rotation situation, to make energization motor transmission shaft not rotate, must several personal yokes, restrict motor
Power transmission shaft binding carries out short-circuit test after killing, due to the binding stall of manpower, the rare loosening in short-circuit test, and the number for measuring
It is just very big according to error.This electric motor short circuit test method, in stall motor, wastes time and energy, and the data accuracy for measuring
It is poor.
A kind of motor stalling tester (publication number of patent：CN201681145U) when stall test is implemented to motor,
It is the through hole that the power output main shaft for treating measured motor is sequentially passed through electric machine main shaft through hole and stall disk on motor mounting plate,
Then tighten the bolt on Hough plate so that two panels Hough plate holds electric machine main shaft tightly, implement the stall test of motor.The structure
Motor stalling tester is had some limitations to the motor for testing different size, it is impossible to be adapted to not concentric height electricity
The stall test of machine, and two panels Hough plate easily crushes the periphery of electric machine main shaft, or even the person that can jeopardize testing crew
Safety.
Utility model content

The angle bar other end is welded with iron hoop, and the lifting rope is tied up on the iron hoop of the angle bar, and the lifting rope other end is connected by spring
The sensor of the cradle top is connect, is horizontal the angle bar, the sensor is LOAD CELLS, described to weigh
The signal output part of sensor is connected with tester, and the tester shows the sensing power for measuring, by surveying described in selection operation
Try instrument and through interior processing unit, the tester shows the locked-rotor torque for measuring.
Preferably, fixing bolt is housed between the motor and base so that motor is more stable firm when working.
Preferably, the support is telescoping shoring column, convenient to adjust sensor height, realizes the not concentric height of measurement
Motor rotation blockage is tested.
Preferably, the frame bottom is equipped with 4 symmetrical road wheels, and convenient adjustment lifting rope position keeps balance.
The beneficial effects of the utility model are：It is using above mechanical system by the motor transmission shaft stall after energization, few
Labor strength, shortens test period, and as stall is solid and reliable, test data accuracy is high.This utility model structure
Simply, it is convenient to operate, as long as electrical power can measure stall data, reduce the potential safety hazard of test.Sensor stand can
Height is adjusted, the motor of arbitrary axle center height is convenient for measuring.
