Large Electric Motor Repair through 19,000 Horsepower

Inman Electric Motors specializes in rewinding and rebuilding large electric motors though 19,000 horsepower. Our service center has 70,000 square feet of space and is equipped with 5, 10, 15 and 40-ton overhead bridge cranes with 32 feet of clear height. Inman processes all rewinds with vacuum pressure impregnation. We have two curing ovens and two heat treating ovens that are the largest in the Midwest. Inman Electric Motors has computerized coil winding machines, as well as instrumentation for performing the following electrical tests: surge comparison, core loss and efficiency, hipot, megger, resistance, inductance, impedance, phase angle, and rotor bar analysis. Our motor test panel has a capacity of 2,500 kva at 13,800 volts A.C. and 700 volts D.C. Motors through 13,000 horsepower are tested at full nameplate voltage. Motors are fastened to a 10,000 pound machined sole plate grouted in an independent foundation adjacent to the testing panel. Complete vibration spectrums are printed and recorded for every tested motor.
