Abstract
A starter for a drive unit, such as an internal combustion engine, includes a stationary and a movable base element which form a linear motor. The movable base element is seated on a revolving shaft of the drive unit an inertia mass of a flywheel of the drive unit. The inertia mass of the flywheel is rigidly connected with the revolving shaft and is acted upon with sufficient torque required for the starting of the drive unit. Upon starting, the linear motor is switched over into a generator operation.
Claims10
A starter for an internal combustion engine having a rotary drive shaft comprising:
- a flywheel coupled to the drive shaft including a passive vibration irradicator for damping interference vibrations of the drive shaft;
- a rotor section located on the flywheel;
- a stator section spaced from the rotor section and together therewith providing an electric motor;
- and
- a control circuit for providing control signals to the electric motor to induce a traveling magnetic flux linkage between the stator section and rotor section.
