Horsepower and Electric Motors . Torque = force x radius = lb x ft = T Speed = rpm = N Constant = 5252 = C HP = T x N / C . Theoretical BHP or Break HP (Actual Motor Amps / Name plate amps)/Motor name plate HP . Torque and DC Motors . T = k Ia At overload, torque increases at some rate less than the increase in current due to saturation

Jun 17, 2002 · Determine maximum percentage voltage dip. This is basically what sizes the generator. If voltage dip is too large, the motor will over heat or not start because there is not enough torque to accelerate the motor. Motor torque falls off approximately as the product of reduced squared. For example, with a 30% voltage dip resultant torque, it will be:

An electric motor turns a flywheel through a drive belt that joins a pulley on the motor and a pulley that is rigidly attached to the flywheel, as shown in Figure P10.39. The flywheel is a solid disk with a mass of 80.0 kg and a diameter of 1.25 m. It turns on a frictionless axle. Its pulley has much smaller mass and a radius of 0.230 m.
