A self-contained clutch for diesel engines for off-highway implementation is provided. A stationary friction disc, pressure plate and endplate sandwich a pair of rotating separator discs. Attenuation of vibration damping of the rotator discs may be achieved by a centrifugal weight. A pulse-width-modulated DC motor or valve is employed in association with a hydraulic actuator to control pressure to the clutch piston. An RFID tag uniquely identifies the nature and parameters of the clutch itself and is associated with the clutch such that the controller can most efficiently operate the clutch. Heat is dissipated by an oil pump servicing the support bearings and/or by the integration of a centrifugal fan into the heat disc stack.

Self-contained clutch for diesel engines

A system for detecting the position of a rotor for a switched reluctance (SR) machine having an irregular pole configuration. The system does not require the use of a conventional sensing device, and provides accurate position information, without disrupting operation of the machine. A voltage ratio is used to infer the position of the rotor relative to the stator.

Sensorless rotor position detection for switched reluctance machines

A circuit for controlling the operation of switched reluctance machines (i.e., motor or generator) having a plurality of phase windings. The circuit slows down the initial 'turn off' of the phase windings to eliminate an abrupt reduction in the current flowing therethrough. This reduces the impulse which excites mechanical oscillations in the motor/generator, reduces switching losses in the switching transistors, and reduces the number of harmonics.
