Highly reliable and consistent starting is achieved by first initializing the rotor position, namely establishing the rotor in a known starting position. This is accomplished by gating on two pairs of SCRs in sequence and supplying current pulses through the gated SCRs to the stator of the motor to rotate the rotor to a first position and then to a second position, the rotor coming to a complete stop in each of those positions. The rotor aligns itself with the magnetic field created by the stator in each position and any ambiguity in the rotor position i...


A starting system for an interter-motor system wherein a synchronous motor, having a stator and a rotor, is normally driven by the output a-c voltage developed by an inverter, which has a series of motor-commutated SCRs that are gated into conduction in predetermined pairs and in a prescribed sequence to conduct current to the motor, from an applied d-c bus voltage, and in response to received bus current, translated to the inverter over a d-c bus and a series-connected filter inductance from a controlled rectifier bridge to which is applied a-c line vol...
