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. -------------------- "Don't assume any thing, always check/ask and clear yourself".

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, -------------------- Mark Empson administrator

Best regards, (1) Motor and gear box is working without any problem (2) yes but ramp up (3) Yes -------------------- "Don't assume any thing, always check/ask and clear yourself".

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. Regards Mario -------------------- |
