An electric motor prime mover and method of starting an electric motor prime mover is provided. The prime mover includes an electric motor, a pneumatic motor and a mechanical coupling operably connecting the pneumatic motor to a rotor of the electric motor. The pneumatic motor initiates startup of the electric motor by driving the rotor of the electric motor prior to applying electrical power to the electric motor. After the rotor has attained sufficient rotational speed electricity is applied to the electric motor to drive the rotor. The use of the pneumatic motor allows the rotor to be rotating as electricity is initially applied to the electric motor preventing or substantially reducing inrush currents.
