Universal, retrofittable powerhead for small gasoline engine power implements

摘要

A universal powerhead apparatus (12) which is securable to a frame portion (14) of a land vehicle (10, 84, 88), pump or other tool to replace an existing internal combustion engine of the device without requiring significant modification to the frame portion of the device. The powerhead apparatus (12) includes an electric motor (26) and a universal mounting plate (16) which is secured to a portion of the motor. The universal mounting plate (16) has a footprint substantially similar to that of a specific make and displacement of internal combustion engine which the apparatus (12) is intended to replace. The overall footprint of the apparatus (12) is also similar to the specific make and displacement of gasoline powered engine which it is designed to replace. The apparatus (12) can be secured directly to a frame portion of a land vehicle (10, 84, 88), tool or pump in either a horizontal or vertical orientation to thus enable it to be used as a power source for vehicles requiring a horizontally disposed output shaft as well as vehicles requiring a vertically disposed output shaft. The apparatus (12) may be assembled to the land vehicle (10, 84, 88), tool or pump in a factory or retrofitted to replace a specific make and displacement of gasoline powered engine. In one preferred embodiment, the apparatus (12) is powered by at least one battery (25) disposed within a housing (20) thereof. In an alternative preferred embodiment, the apparatus (12) is powered directly from an AC power source. The use of the apparatus (12) completely eliminates the undesirable emissions produced by internal combustion engines and the periodic maintenance typically associated with such engines.
