50hz Motor On 100hz

[AB2005]

Dear All

 

We have an application where we have to run a 380V, 50Hz, 1.5Kw, 4poles geared motor (20rpm) on 100Hz. This motor works for a short moment; 25sec working time and 25minutes rest time. What would be any disadvantages for that usage? Any care should i taken for a preventive action as we are runing 10 motors in same pattern.

Hello AB2005

 

My concerns would be 1] can the motor and gearbox operate at that speed without problems and 2] as the motor output is limited at 100 Hz, will there be sufficient torque available for the load.

 

Best regards,

(2) yes but ramp up

Dear AB2005,

I would recommend to check the lubrication, on some gearboxes at double speed the standard lubrication is not enough effective. Usually in sich cases I recommend an american additive, as super-lubricant.
