PURPOSE:To improve a power factor of the whole circuit including a motor by providing a power-factor improving capacitor at the rear of a full-wave rectifier circuit. CONSTITUTION:An input current of a portion with a phase opposite to a motor input voltage phase is applied to reflux diodes ...
However, keep in mind that the formula above is only applicable to DC sources. Determining the electric power input for anAC sourcemust include a power factor. Power factor is a measure of how effectively electrical power is being used. It is the ratio of the electrical power that the motor...
If electric motor power factor sounds a bit intimidating or mysterious, see details at DEFINITION of POWER FACTOR or in the formulas below, if you don't know the power factor pf or PF for your motor, a reasonable starting point is 80% or 0.8. (The actual PF when a motor is startin...
