motor

Hello Sohail Shahid

Yes, any motor may be overloaded, for a short time..

Just don't expect it to survive for long.

Kind Regards....

It will also consume more power than the rated 7.5 kw while it delivers more output power.

I think your losses will also be more compared to normal while running at overload.

This can be confirmed if the volts and amps are recorded.

I presume you are asking is it advisable instead of available.Motors are designed to operate with temp rise within limits depending upon the insulation.Normally ambient is taken as 40Deg c .Let's say if it is having class be then total temp rise should be within 120DEG or 80Deg temp rise over ambient.10DEG cushion is built for hot spots.so if your ambient is low you may overload.The motor is overloaded by 17% on rated capacity.Check temp .However as already mentioned the eff and pf will become lower at this point and it may consume more power.Life depends on how much you are exceding the temp limit.

Hello Hendrik

It will consume more power than the rated 7.5 kW even when it's delivering rated output power!

7.5KW is the power out put at the shaft.The input power will be 7.5 divided by efficiency at 100%.

Sure the motor will deliver an output of 8.8KW beyond it's rated KW. But considering energy efficiency,motor life and load, I'd assume the motor rated KW is not the right size for the load. Additionally, the transmission gears and or gear box is not energy efficient and is adding extra strain on the motor as with the load it is driving. Consider using a motor that would carry the load at rated 8.8KW and the gearing transmission.
