After the starting of the motor, the heating exceeds the standard of temperature rise or smoke
Date:2017-12-04 Num:1618
Possible reasons:
(1) the power supply voltage is too low, and the motor is too high under the rated load.
(2) poor ventilation of the motor or high humidity of the environment;
(3) motor overload or single phase operation;
(4) the frequency of motor starting frequently or the number of positive and reverse times is too much.
(5) the stator and the rotor are rubbed.
Treatment methods:
(1) measurement of no-load and load voltage;
(2) check the motor fan and clean air, strengthening ventilation to reduce environmental temperature;
(3) using the current clamp type table to check the current of each phase after symptomatic treatment;
(4) to reduce the number of motor, motor or replacement suitable for frequent starting and positive inversion;
(5) check after aunt disease treatment.
