If an AC Induction motor is drawing higher than desired current and has a lower than desired power factor, how can I increase the power factor to reduce the current draw?

Hello Grut

Welcome to the forum
You can improve the power fctor of a motor by adding capacitance in parallel with it. This can be achieved at the main switchboard (bulk correction) or at the motor itself (static correction). Have a look at our page on power factor correction and this may answer some of your questions. http://www.lmphotonics.com/pwrfact.htm
Adding power factor correction will reduce the current drawn from the supply, but will not reduce the current into the motor itself. Sometimes, the current can be reduced by the use of an energy saving device. This requires that the motor is well unloaded. see http://www.lmphotonics.com/energy.htm
Any further uestions, post them here.
