Steady State Dynamic Operating Behavior of Universal Motor

A detailed investigation of the universal motor is carriedout and used for various dynamic steady state and transient operating conditions of loads. In the investigation, output torque, motor speed, input current, input/output power and efficiency are computed, compared and analyzed for different loads. This paper discusses the steady-state behavior of the universal motor. A non-linear generalized electric machine model of the motor is considered for the analysis. This study was essential to investigate effect of output load on input current, power, speed and efficiency of the motor during operations. Previously such investigation is not known.
