I、What is the no-load current range of a 37KW 4-pole motor with a frequency of 60 Hz? What will be the effect on the motor if a 60 Hz motor is used on a 50 Hz power supply? The no-load current range of a 37KW 4-pole motor with a frequency of 60 Hz is about 31A; if a 60 Hz motor is used on a 50 Hz power supply, it will have no effect on the motor, and the current will be about 28A. If, If it is new or has been out of service for too long, a current slightly higher than this is normal. If it is lower than this, it only proves that the motor is very good.
II、What is the shaft diameter of the 37kw 4-stage motor? How wide is the keyway?The shaft diameter of the Y series 37kW 4-pole motor is φ60, the keyway width is 18, the keyway depth is 7, and the model is Y225S-4.
