Claims

[Scope of utility model registration request]

A DC output is applied from the AC power supply through a forward converter and power is supplied to the armature winding of the synchronous motor from the reverse converter, and the AC power input is obtained and applied to the field winding of the synchronous motor through the rectifier circuit. In the non-commutator motor, there is provided a logic signal generation circuit that detects the phase voltage of the synchronous motor and provides a logic signal of the phase voltage;
2) A logic for providing a pulse signal generation circuit that provides a pulse output having a cycle, inputting the output of the logic signal generation circuit and the pulse signal generation circuit, and retaining the logic signal output in the pulse output for the pulse output cycle. A rotor position detection circuit for a commutatorless motor, characterized in that a circuit output signal is obtained.
