What problems should be paid attention to when the motor works beyond 60Hz?
The following precautions should be taken when operating beyond 60Hz
(1) Machinery and equipment should have sufficient potential to work at this speed (mechanical strength, noise, vibration, etc.).
(2) When the motor enters the constant power output range, its output torque should be able to keep working (the output power of the shaft of the fan and pump is added to the cube of the speed, so it should be noted when the speed is slightly increased).
(3) The life of the bearing should be fully considered.
(4) For motors with medium capacity or above, especially 2-pole motors, it is necessary to consult with the manufacturer carefully when working above 60Hz.
