PROBLEM TO BE SOLVED: To provide a method of generating a rotor position dependent pulse width modulation waveform in operating a brushless direct current motor, where the waveform improves motor efficiency and reduces torque variation.SOLUTION: Control of a brushless direct current motor comprises: generating a motor command signal during a commutation interval of the brushless direct current motor; and adjusting a common attribute of a plurality of non-zero pulses included in the motor command signal such that those non-zero pulses are not uniform. |
