NettetAnother common but popular unit of power that motors are rated in is watts. The conversion from watts to horsepower is: 745.7 watts = 1 horsepower. Or 1 hp =746 watt. Also, One Horsepower equals to 33,000 lb. ft/min. Horsepower formula is: Horsepower =. With another computation, Horsepower = weight ×. NettetTo calculate the torque for your gearmotor, you will need to know the motor's horsepower (HP) rating and the gearbox ratio. Once you have these two pieces of information, you can use the following formula: Torque (lb-ft) = (HP x 5252) / RPM x Gearbox Ratio. Where: HP is the horsepower rating of the motor; 5252 is a constant; RPM is the speed of ...
