摘要： A method of controlling an electrical machine, the method comprising selecting an edge of a rotor-position signal as a reference edge and commutating a phase winding of the electrical machine at times relative to the reference edge. The rotor-position signal has at least four edges per mechanical cycle, each of the edges being associated with a respective zero-crossing in back EMF or minimum in inductance of the phase winding. The angular position of at least one of the edges relative to its respective zero-crossing or minimum is different to that of the other edges. The reference edge is then selected from the edges such that the angular position of the reference edge relative to its respective zero-crossing or minimum is the same with each power on of the electrical machine. Additionally, a controller and control system that implement the method.

摘要： A method of controlling a brushless motor that comprises storing a lookup table, the lookup table comprising a control value for each of a plurality of speeds, periodically obtaining a speed-adjusted control value, and exciting a phase winding of the motor, wherein the speed-adjusted control value is used to define one of a phase and a length of excitation. Obtaining the speed-adjusted control value comprises measuring a speed of the motor, increasing or decreasing a speed-adjust variable by a predetermined constant in the event that the measured speed is greater or less than a threshold, selecting a control value from the lookup table using the measured speed, and adjusting the selected control value using the speed-adjust variable to obtain the speed-adjusted control value. Additionally, a control system that implements the method, and a motor assembly that incorporates the brushless motor and the control system.
