Motor testing standards
 
The motor testing standard is designed to ensure the safe operation and improve the service life of the motor, by evaluating its performance through a series of testing items. Here are some detailed information about motor testing standards:
 
Content and purpose of motor testing report
 
The motor test report includes various performance indicators of the motor, such as voltage, current, power, speed, torque, efficiency, etc. These data can be used to determine whether the motor meets the design requirements, the quality, and the goals and directions for improvement.
 
The purpose of motor testing is to detect the operation of the motor, determine whether there are any abnormal situations, and analyze and evaluate the test results in order to take targeted measures to ensure the safe operation of the motor and improve its service life.
 
Common items for motor testing
 
Common items for motor testing include:
 
-Appearance inspection: Check whether the motor casing is deformed, damaged, cracked, etc.
-Insulation test: Test the insulation performance of the motor, such as dielectric strength, insulation resistance, etc.
-Excitation detection: Check whether the excitation of the motor is normal.
-Axial and radial clearance detection: Check whether the axial and radial clearances of the motor rotor meet the requirements.
-Motor speed and power testing: Test whether the rated speed and power of the motor meet the standards.
-Noise test: Test whether the noise level of the motor during operation meets the requirements.
-Vibration test: Test whether the vibration level of the motor during operation meets the requirements.
 
Management of motor testing standards
 
The management of motor testing standards includes regulations on appearance requirements, electrical parameters, safety performance, and other aspects. For example, the appearance requirements include the correct positioning of the positioning holes, the structural dimensions of the housing and shaft in accordance with the drawing requirements, and the length and color of the lead wires in accordance with the requirements.
 
Electrical parameters include the determination of insulation resistance between windings and ground terminals, as well as between windings, withstand voltage tests, no-load tests of motors, and stall tests.
 
Safety performance includes the measurement of DC resistance of windings in actual cold state, inspection of no-load characteristics and smoothness of operation, phase sequence inspection, spark testing of DC, single-phase series excitation, AC rectifier motors, etc.
