- Scope
- This standard applies to three-phase cage-type asynchronous motors and specifies two methods for determining efficiency: ·Method 1: Use a torque measuring device for the motor test, and calculate the stray loss value of the load according to the test results. ·Method 2: The motor test does not measure the torque, and adopts the recommended load stray loss value. The difference between these two methods lies in the method of determining the stray loss of the load. Unless otherwise specified, method 1 is suitable for motors of 15OkW and below. For other methods of determining efficiency, see GB/T 755.2-2003.
