الحصول على السعر· If you design around a load of X, and actually lift a load of 80% of X, the motor will be able to spin about 1/.8 = 125% the speed and will draw about 80% as much current due to producing 80% as much torque. This won't necessarily be perfectly accurate due to losses from friction and motor efficiency, but it will hold mostly true for loads that don't drastically differ.
