  • Motor Efficiency Power Factor and Load EC M

    The PF of a motor is lower when the motor is under-loaded and is significantly reduced when the motor load is less than 70 . Closely matching the motor to the load is the best way to keep the PF close to the motor design rating which is typically 80 to 85 PF. Motor system power factor improvement project
