low power factor of crusher motor
Motor torque, load torque and selection of motors
ResultMotor torque, load torque and selection of motors 2/45 Performance In such motors the pull-out torque is normally less than the starting torque. This is because the pull-out torques by the two cages occur at different speeds. Such motors would possess a low power factor and efficiency compared to an ordinary squirrel cage …

Reducing Power Factor Cost
ResultLow power factor requires an increase in the electric utility's generation and transmission capacity to handle the reactive power component caused by inductive loads. Utilities usually charge a penalty fee to customers with power factors less than 0.95. You can avoid this additional fee by increasing your power factor.

Causes And Disadvantages Of Low Power Factor
ResultWhereas at a low power factor (say 0.8), the Full load current will be = 20000/250*0.8 = 100A. Here from the above example, it is clear that if a motor works at a poor power factor of 0.8 then it draws more line current than at unity power factor. Hence we required a greater conductor size at a low power factor.

Power Factor: Improvement & Correction Methods
ResultPower factor is a dimensionless number in the closed interval of −1 to 1. The "ideal" power factor is one (also referred to as "unity"). This is when there is no reactive power through the circuit, and hence apparent power (kVA) is equal to real power (kW). A load with a power factor of 1 is the most efficient loading of …
