Embodiment Construction

[0026] The present invention can be used in vehicles powered by electric motors such as disclosed in co-pending application 09 / 826,422, and can also be used with various other permanent magnet motors. figure 1 is a schematic diagram showing the rotor and stator elements of the motor 10 described in that application, the disclosure of which is incorporated herein. The rotor part 20 is an annular structure with permanent magnets 21 approximately evenly distributed along a cylindrical support plate 25 . The permanent magnets are rotor poles that alternate magnetic polarity along the inner periphery of the ring. The rotor surrounds a stator part 30 which is separated by an annular radial air gap. The stator 30 comprises a plurality of electromagnetic core pieces of identical construction, evenly distributed along the air gap. Each core piece comprises a generally U-shaped magnetic structure 36 forming two poles with a surface 32 facing the air gap. The legs of the pole pair are...

Abstract

A novel system for adaptively controlling an electric vehicle to maintain desired speed under variable driving conditions. The system includes a control circuit for producing a control signal to control an electric motor of the vehicle. The control signal is formed based on a control current required to achieve the desired speed. The control strategy selection circuit is configured in the system to determine a motor control scheme that provides an appropriate waveform profile of the control current.
