Rzn Posted October 17, 2006 Report Share Posted October 17, 2006 Dear All, There are many kind of single phase motors available in market. Some motors have capacitors which remains connect with supply after motor starting like ceiling fan etc. Some motors capacitors disconnect through centrifugal switch after start up. We have such kind of motors in our plant. I want to know what is the power factor of such single phase motors? I have no data sheet for these motors as they are too old.

marke Posted October 17, 2006 Report Share Posted October 17, 2006 Rzn There is no standard power factor for motors, it varies from motor to motor. If you do not have a specification, (it is commonly on the name plate of the motor) then you must measure it. The power factor varies with load as well, so the datasheet will typically quote the full load power factor, 75% load and 50% load.
