Electric propulsion device, particularly in one, two or more driving wheels vehicles and vehicle with such propulsor device

摘要

A propulsion device of the electric motor type, particularly for vehicles with one, two or more driving wheels, comprises at least one electric motor (2, 2') of the type known as "brushless" which is connected dynamically to at least one driving wheel; an electronic power supply unit for the said brushless motor, with a source of direct-current electrical energy (1), a unit (4, 6) generating a three-phase alternating current to operate the motor (2,2') from the said direct current power supply, and with at least one feedback loop (7, 9) which controls the alternating operating current generating unit (4, 6). According to the invention, a microprocessor (7), into which the control and regulation logic is pre-loaded in the form of at least one program, is provided in the feedback loop (7, 9), as the logic component controlling the alternating operating current generating unit (4, 6) and as an interface with means (2, 2', 15) of detecting the operating conditions of the motor (2, 2') and/or means (10, 110, 210, 310, 16) of presetting the operating conditions.
