Motor 60Hz work should pay attention to what
60Hz work should pay attention to the following:
(1) machinery and equipment in the speed run to full potential (mechanical strength, noise, vibration, etc).
(2) motor into a constant power output range, the output torque can be maintained (fan, pump shaft output power is proportional to the cube of the speed increase speed a little higher should also pay attention to).
(3) the bearing life issues to be fully taken into account.
(4) for more than the capacity of the motor, especially 2-pole motor, 60Hz operation should be carefully discussed with the manufacturers.
According to structure of reducer and lubrication in a different way, you need to pay attention to several problems. Gear structure can often be considered 70~80Hz for maximum limits, using oil lubrication, at low speed continuous operation related to gear damage, etc.
