Claims

[Scope of utility model registration request]

It consists of a rotation angle detector that detects the angle formed by the rotor magnetic axis and stator magnetic axis of the electric motor, the product of a trigonometric function that uses the angle given in advance as a variable, and an amount that increases the magnitude of torque. Drive information is stored in a storage area corresponding to an input address, and the electric motor is fixed from the corresponding storage area by address input of the output signal of the rotation angle detector and a torque command signal that defines the magnitude of torque. A storage circuit that outputs drive information in a number equal to the number of child phases, and a power amplifier that amplifies each of the drive information output from the storage circuit and drives the corresponding stator winding of the motor. Features a brushless motor drive device.
