摘要：A method and an arrangement are provided for controlling a sensorlesspermanent magnet synchronous machine using a frequency converter connected to feed

the machine with electrical power. A current a current vector having a magnitude isproduced to the stator of the machine with the frequency converter, and the currentvector is rotated for rotating the rotor of the machine. Prior to starting the drive, a valueis defined for the magnitude of the current vector and a frequency limit. The definedvalue is used as the magnitude of the current vector when the rotor of the machine isrotated with a frequency that is lower than the defined frequency limit. A vector controlmethod is used for controlling the machine when the frequency of the machine is higherthan or equal to the defined frequency limit.
