Understanding motor drive efficiency and performance. By Han Tran, Application Engineer, Fluke
Motor drives are a ubiquitous technology for transforming the constant voltage from the main AC power supply into a voltage that varies to control motor torque and speed ideal for motors that are driving mechanical equipment loads. Motor drives provide higher efficiency than simple online motors and a degree of control not available on simple directly driven motors. These factors result in energy cost savings, higher production performance and extend the life of the motor.
