A power module is connected to the starter, alternator, and battery for an internal combustion engine. The power module includes one or more capacitors and delay timer. When the ignition switch closes, the battery of the starting system provides current to the starter motor, causing the starter solenoid to close the starter contacts, and bring a starter pinion gear into engagement with a flywheel ring gear. The delay timer does not allow the capacitor to immediately deliver current to the starter motor, but implements a short delay before the capacitor's current is released to the starter motor. This short delay increases the chance for full engagement between the starter pinion and the flywheel ring gear, thereby reducing the likelihood of milling when the starter motor provides torque to the starter pinion.

Engine starting motor anti-milling device

Systems, methods, and apparatus, consistent with principles of the present invention, allow an unmodified device, for example, a dc starter motor, that normally operates at a first voltage to function in an electrical system providing a second voltage, which is different from the first voltage, and received from the power source. A device actuator, such as a solenoid, is controlled using the second voltage. The first voltage is produced and supplied to the device in response to a first action of the actuator, for example, upon solenoid depression. This voltage is then inhibited from being provided to the device in response to a second action of the actuator, for example, upon solenoid retraction after engine cranking.

Electrical control circuit and method

A powdered magnetic material stator core with embedded stator windings and a method for its manufacture. Embedding the windings within a radially compacted powdered magnetic material stator core enables equivalent or better electromagnetic performance in a significantly reduced size. Radial compaction of the powdered magnetic material minimizes the distortion of the stator windings during compaction.

Electromagnetic device with embedded windings and method for its manufacture

Disclosed is a process for producing an AC cylindrical electromagnetic ignition coil core (28) comprising: filling a cylindrical holding container (20) with powdered metal; placing the filled container into an electromagnetic field and compacting, in the radial direction, the powder in the container by subjecting the powder to the electromagnetic field; and recovering the compacted ignition coil core (28).

Electromagnetic compacting of powder metal for ignition core application

In a charge/float vehicle electrical system, heavy battery charging is effected during periods of engine deceleration and the float voltage is adjusted so as to maintain the battery state of charge at the level in existence at the initiation of the float mode.
