APPLYING MICROCONTROLLER AND ZHKY901 SENSOR IN A MODEL OF SUPERVISING MOMENT ELECTRICAL MOTORS USING IN SMALL REPAIR AND MAINTENANCE CENTERS

Abstract

After long time operation, electrical motors always need checked and repaired by technical staffs of plants or the workers of maintaining workshop. Technical
parameters of the motors have been tested before returning to operate in plant. Among many of testing motor parameters, the torque value is quite difficultly
measured, because it needs a complicated measurement system. Today, testing motor systems are more complicated, too cumbersome and expensive. These systems
are usually applied in testing centers of motor manufacturers, national quality testing centers and universities’ motor testing room. But, they are not suitable for using
in a small maintaining factory workshop. Therefore, a small motor testing system with low cost and torque measurement, convenient using is necessary.
For this reason, this paper proposes and designs a motor testing system which applying microcontroller and ZHKY901 torque sensor for checking motor torque.
Two Y3-80M1-4 B3 induction motors, one is new, the other is old are tested by this system. The results will show the reliability of the system.
