DRIVE CIRCUIT

The above shows the conceptual scheme of drive circuit.

STARTING

STARTING

To start the motor, the starting circuit drives it as a DC brushless motor.For introduction of synchronous rotation, starting circuit keeps rotation close to synchronous one. The circuit starts synchronous running when the motor rotation phase comes in the specified tolerance against the power phase.

SYNCHRONOUS RUNNING

SYNCHRONOUS RUNNING

For synchronous running, starting circuit is disconnected and motor coil is directly connected to AC power to run the motor as an AC synchronous motor. Controller monitors the condition during synchronous running.
