Abstract
A method includes receiving a first measurement signal representing a first time between transitions of a motor commutation state. The method further includes receiving a second measurement signal representing a second time between transitions of a motor floating terminal voltage. The method further includes determining a motor speed state based on a combination of the first and second measurement signals, determining a motor commutation state based on the motor speed state and the motor floating terminal voltage; and providing a control signal to a motor inverter based on the motor commutations state.
