An improved DC electrical starting motor and method for starting internal combustion engines that reduces starter motor noise in the period after the engine starts by effecting breaking of the starter motor shaft at that time. Preferably the braking is acc...

A very effective and easily assembled low cost rotating electrical machine useable as a starter motor. The commutator is formed at the end of the rotor shaft opposite to its drive end to minimize bending loads on the plain bearing at that end of the rotor ...

An improved method and system for the control of an engine system such as the spark timing. The control senses the speed variations either during a portion of a complete cycle and a complete cycle and/or from cycle to cycle in order to determine the load o...
