A motor of wrong rating is not reliable. If the rating of motor is below the required value, there is high possibility of winding damage, whereas using of motor of rating much higher than required will result in poor efficiency. So the use of rated motors is recommended for good & efficient performance. The motor rating used is slightly higher than the required load value for safety purpose,as electric motors have the capability to withstand overload situations.
