    • A method for starting a multiphase, sensorless commutated, brushless electric motor. The method has three operating phases. A start-up phase in which the motor is operated from a standstill with specified commutation times. An acceleration phase in which the motor is accelerated up to a nominal speed, wherein the commutation times are determined on the basis of the zero crossings of the BEMF voltage of the non-energized stator phase windings. And a stationary operating phase in which the nominal speed is kept constant. The transition from the start-up phase into the acceleration phase takes place when, during the start-up phase, a predetermined number of successive zero crossings of the BEMF voltage in the expected order in the expected motor phases have been identified. The transition from the acceleration phase into the stationary phase takes place once the nominal speed has been reached.

    • In a synchronous machine starting device, an AC voltage detection unit detects AC voltage supplied to an armature of a synchronous machine through an electric power line from a power conversion unit. The AC voltage detection unit has a first output end and a second output end isolated from the electric power line, transforms AC voltage supplied through the electric power line at a first ratio to output the transformed voltage from the first output end, and transforms AC voltage supplied through the electric power line at a second ratio and then limits the transformed voltage to a prescribed positive voltage value or lower and a prescribed negative voltage value or higher for output from the second output end. Then, a detected voltage selection unit selects one of the voltage received from the first output end and the voltage received from the second output end, and outputs the selected one to a rotor position detection unit. The rotor position detection unit detects a rotor position of the synchronous machine based on the voltage received from the detected voltage selection unit. A power conversion control unit controls the power conversion unit based on the detected rotor position.
