A synchronous motor absorbing 60 kW is connected in parallel with an continuous load of 240 kW operating at 0.8 power factor lag.What is the kVAR supplied by the synchronous motor to obtain a total power factor of 0.9 lagging?

Electrical machines have many applications, including:   Compressors: Use an electric motor or engine to drive a compression mechanism that pressurizes air. DC motors: Convert direct current electrical power into mechanical power. Electrical drives: Convert electric energy into mechanical energy and control the system's electrical or electronics. Conveyors: Use rollers powered by an electric motor to move cartons to different areas. Electromagnetic induction: Used to energize a wide range of electrical equipment, including electric generators. Design optimization: Use electromagnetic... Show more
