A method of disconnecting a generator from a source of mechanical rotation includes receiving a generator disconnect command and receiving a rotational position of a generator input member. The input member rotational angle is compared to the target disconnect angle range, and a determination made whether to disconnect the input member from a generator drive member based on the comparison.

A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. An integrated actuator housing includes a single external power access for the shift actuator. A controller interprets controls the shift actuator with actuating and opposing pulses, and interprets a shaft displacement angle, determines if the transmission is in an imminent zero or zero torque region, and performs a transmission operation in response to the transmission in the imminent zero or zero torque region.

An angle-measuring device is provided for a rotationally-driven linear actuator, which can be implemented into a clutch actuator. A rotor element has an axis of rotation and rotates concentrically with a rotor of a rotary drive for an axially movable linear actuator element. A measurement magnet arrangement is fixed relative to the rotor element and has a polarization. The polarization is oriented in such a way that the magnetic field lines can change with a rotation of the rotor element so as to enable the angle to be precisely determined from at least one measurement position. At one location, a 360-degree sensor is provided for measuring angular positions based on the measurement magnet arrangement. At another location, a revolution-counting sensor is provided for counting a number of revolutions carried out based on the measurement magnet arrangement.
