Permanentmagnetsynkronmotor med elektronisk indretning til start af motoren og med sensormidler, hvis postion er afhængig af den af motoren drevne belastning

摘要

An electronic device for starting a permanent-magnet synchronous motor, comprising logic control means, at least one switch arranged in series between a power supply source and a permanent-magnet synchronous motor, sensor means suitable to determine the polarity and position of the rotor of the motor, the logic control means being suitable to send a driving signal to the switch means as a function of a signal that arrives from the sensor means and a voltage signal of the power supply source.
