An electric clutch actuator capable of operating in two power loss conditions. For a condition where a normally engaged clutch is disengaged during a system power loss and the desired action is for the clutch to remain in the disengaged positional state, a holding device moves to a power off activated position to prevent movement of an actuator for the clutch. For a condition where the clutch is disengaged during a system power loss and the desired action is for the clutch to move to an engaged positional state, a motor in the electric clutch actuator is used as a generator to convert the potential energy of a clutch pressure spring into electrical energy to provide energy for powering the holding device to remain deactivated, permitting movement of the clutch actuator to the engaged position. Maintaining the holding device deactivated permits the clutch to move to the engaged position and thereby allows vehicle engine braking to be used during a power loss of the system.
A stator winding for a slotless motor is parallel with the longitudinal axis of the motor except at the end turns of the coil windings. The coils have concentrated windings with a pair of coils wired in series to form one phase of the stator windings. Each of the pair of coils are wound such that the magnetic flux produced by a dc current through the coils produces magnetic flux of opposite directions with respect to the rotor of the motor.

A method for attenuating switching noise from back electromotive force (EMF) observations in a motor is described. The motor is controlled by pulse width modulation (PWM) signals provided at a PWM frequency. The method comprises sampling back EMF observed in the motor at a sampling frequency at least two times greater than the PWM frequency to obtain over-sampled back EMF readings. The oversampled readings may be used in a raw or filtered form to commutate the motor. A system implementing the method is also described.
A method for adjusting a rotational speed of a rotor in a polyphase motor from a first speed towards a second, faster speed when the motor is commutating according to a commutation scheme at a first commutation phase angle is described. The method comprises selecting an advanced phase angle relative to the first commutation phase angle for commutating the motor; and adjusting the commutation scheme to be commutating at the advanced phase angle, so that the rotational speed of the rotor increases from the first speed towards the second speed as the motor is commutating at the advanced phase angle. A system implementing the method is also described.

Methods for evaluating back electromotive force (EMF) in a polyphase motor is described. The methods include monitoring back EMF in the motor after a commutation of the motor, and evaluating the back EMF only after a back EMF event occurs after the commutation of the motor. The methods may also include monitoring a total current appearing on all phase windings of the motor after a rotor of the motor begins to rotate, and evaluating back EMF only after the total current is within a predetermined margin of the current supplied to the motor. Systems implementing the methods are also described.
