PROBLEM TO BE SOLVED: To obtain sine wave drive at a reasonable price both at transient response and at start without using a position detector such as an encoder, etc., by detecting the magnetic flux of a motor. SOLUTION: This motor controller enables sine wave drive from the time of start by having a magnetic flux detector 102 which detects the magnetic flux of the motor directly or indirectly, and a speed controller 106 which drives the motor by sine waves using the position detected by a position signal converter 110 which converts the quantity of magnetic flux of the magnetic flux detector 102 into the position of the motor, and further even at transient time, sine wave drive can be always obtained at a reasonable price. |
