variable speed mechanically-driven vehicular water pump with supplementary electrical drive

The mechanical drive shaft 3 is engageable with the pump impeller 4 by a clutch 8,12,20,22. The electrical drive comprises a rotor, in the form of magnetic elements 12 attached to the impeller 4, a stator 24,15 including coils 28 arranged around the impeller 4 in proximity to the coils 28, and a pow...

description	The mechanical drive shaft 3 is engageable with the pump impeller 4 by a clutch 8,12,20,22. The electrical drive comprises a rotor, in the form of magnetic elements 12 attached to the impeller 4, a stator 24,15 including coils 28 arranged around the impeller 4 in proximity to the coils 28, and a power supply to the stator. The clutch 8,12,20,22 is arranged to rotationally disengage the rotary driving member 3 and the impeller 4 when the electrical drive is energised to rotate the rotor 12 at a rotational speed above that of the rotary driving member 3. Other embodiments include the use of an over-run clutch, and a combined electrical drive and magnetic clutch, the latter is not implicitly claimed for.
