Abstract:
A motor controller includes: a velocity calculation unit for obtaining an angle θ(n), which shows a rotation position, and an angular velocity ω(n) of a rotor at a time point n; a compensation amount calculation unit for calculating a compensation angle Δθ by which the rotor advances from the time point n to a (n+1)th control cycle (a control cycle starting from a time point n+1), based on an angular acceleration a(n) of the rotor, an angular velocity ω(n) of the rotor at the time point n and a time length T of the control cycle; and a PWM inverter for controlling a voltage to be applied to a coil such that a rotating magnetic field based on a rotation position of the rotor advanced by the compensation angle Δθ from the rotation position of the rotor at the time point n is formed in the (n+1)th control cycle.

Claim (Index 6):
The motor controller according to  claim 5 , wherein\n the voltage controller controls the voltage to be applied to the coil according to PWM control, the control cycle is a PWM cycle, the first time point is a start time point of the first control cycle, a time point in a middle of a pulse output time period in the second control cycle coincides with a time point in a middle of the second control cycle, and the processor sets the coefficient greater than 1.5 when the angular acceleration of the rotor is positive, and sets the coefficient less than 1.5 when the angular acceleration of the rotor is negative.
