Converting Tons Per Hour to KWH Electric motors

Sep 18, 2008Assume that the motors are running at 90% power factor at full load, unless the actual power factor is marked on the motor. If it is marked, use that figure. The relationship between load and amps is non linear because of the magnetizing current which is 90deg out of phase with the real current.

Field-oriented control for motors Machine Design

Field-oriented control for motors. Once estimated and measured currents match, and input voltages are the same for the motor and its model, the motor back-EMF is calculated by solving for es. The input currents and voltages then match between the model and actual motor, the model's correction factor, z, can be filtered to determine the model's back-EMF.

May 24, 2004As the speed of the motor increases, the power factor also increases. When the shaft is stationary, there is no shaft power, only shaft torque. Shaft power is a function of rotational speed and torque. There is input power to the motor however, and that is dissipated in the stator and the rotor.

Power Factor myelectrical

Power Factor Power factor is the ratio between the real power (P in kW) and apparent power (S in kVA) drawn by an electrical load. The reactive power (Q in kVAr) causes the real and apparent power to be displaced from each other. Reactive power provides the necessity for electric and magnetic fields to enable the power system to work.
