    VFD Effects on Motor Heat Output

    To find average heat losses on a motor, it can be quickly determined using the rated HP and efficiency. EX. A 200 HP @1800 RPM and 95% eff. 200 HP x (1-.95) = 10 HP 10 HP x 2550 = 25,500 BTU/hr (25,500 BTU/hr) / (12,000 BTU/hr) = 2.125 Tons But what if the motor is run off a VFD...
