Can any one please me that what is the difference between no load speed and rated speed mentioned in the datasheet of DC motors?
Secondly if i require 20 rpm at the output of the motor when it is operated under nominal load, and motor no load rpm is 3000 while rated rpm is 2000 rpm, than should i design reduction ration according to no load rpm or rated rpm? i.e. reduction ration will (3000/20) or (2000/20)? I am confused about that.
Hi,
]The no load speed is the RPM at which the DC Motor’s shaft rotate when there is no load attached to it (no torque applied to the output shaft). It is the maximum output speed of the motor. The rated speed is the speed at which the motor will first produce its maximum designed power output, and “maximum speed,” the fastest the motor can spin while producing that same amount of power./:m]
]The reduction ratio should be applied on the RPM while your load is attached to the motor. If your load applies the same torque as the rated torque of the motor, the reduction should be applied on the rated speed./:m]Regards,
