Abstract
A method for braking a single coil BLDC motor includes iterating a plurality of times through a sequence of: a braking state which lasts a braking period; and a high impedance state which lasts a cool down period. The current runs through the single coil during the braking state and no current runs through the single coil during the high impedance state. The transiting from the braking state to the high impedance state is done when the motor operates in generator mode.
