The single phase motor controller is an integrated microprocessor system containing Soft Start, Soft Stop and the operating motor controller functions. The development of control characteristic allows , depending on the motor, adjusting the power supplied to the motor maintaining the engine speed above the nominal value. Continuous measurement of current drawn by the motor enabled machine protection against overload and short-circuit effects (reduction of currents).
