Title: A method of determining a position of a rotor of a brushless permanent magnet motor
Inventor: MATE HORVAT
IPC: H02P6/182
Filed: 2022-05-05
Abstract: A position of a rotor brushless permanent magnet motor (PMM) is determined by: exciting a phase winding of the motor over an excitation period E1, by applying a voltage to the phase winding using an inverter of the motor; and turning off the inverter for a time period. During the time period, multiple values, indicative of a back EMF induced in the winding, are measured, from which a phase of the back EMF induced in the winding is calculated. A zero-crossing point of back EMF induced in the winding is determined using the calculated phase of back EMF, wherein an aligned position of the rotor is determined when the back EMF is at the zero-crossing point. The phase winding may be freewheeled for first and second freewheel periods FW1, FW2. The first freewheel period starts at an end of the excitation period, while the zero-crossing of back EMF induced in the winding occurs during the second freewheel period. Zero-current clamping may be performed when the inverter is turned off for the time period. The zero-crossing point of the back EMF may be determined based on one or more of a calculated phase, amplitude and frequency of the back EMF. The phase of the back EMF may be calculated by integrating the measured values of back EMF. The phase winding may be commutated at a commutation time measured relative to the zero-crossing of back EMF induced in the winding.
