what testing should be done before putting a new motor on use?
Answers
Answer:
There are various kinds of testing done on motor. They are:
Electric Motor Impulse Testing
Electric Motor impulse testing is an integral part of predictive maintenance of electrical motors. Below are few questions that helps in explaining the influence of extensive impulse testing on a motor.
Explanation:
1. Electric Motor Rotation Testing
Check for fan or pump motor rotation when testing offline with the MCE.
2. Wound Rotor Electric Motor Testing
Wound rotor motors have a three-phase winding wound on the rotor which is connected to three phases of start-up resistors to provide current and speed control on start-up.
3. Electric Motor Insulation Resistance Testing
Electric motor insulation exhibits a negative temperature coefficient, meaning as temperature increases, resistance decreases. This will make you certain that insulation resistance of a de-energized motor will reduce after commencing the motor.
