Abstract
Methods and apparatus for compensating for non-sinusoidal BEMF signals in an electrical motor using amplitudes, phases and orders of BEMF harmonic components and amplitude of 1st harmonic of BEMF of the electrical motor. First and second corrective components for vd and vq of the d-q coordinate system for the motor can be generated from amplitudes of the BEMF harmonic components and the angles of the BEMF harmonic components orders of the BEMF harmonic components and amplitude of 1st harmonic of BEMF.
