Abstract: The present invention relates to the field of electric-motor-driven vehicles such as cars, motorcycles, scooters, electric-motor trains, etc. Embodiments of the invention seek to provide an economic all-wheel-drive (AWD) vehicle possessing high dynamic characteristics and a relatively simple scheme of control over the operation of electric motors. An AWD vehicle according to the disclosed invention contains at least two gearless (direct-drive) electric motors, an electric power supply source, and an electric motor power supply control unit. At least one of said motors is a start-up (barring) motor and at least one is a cruise (propulsion) motor.
Abstract: The invention relates to electric motors, particularly to low-voltage gearless commutator motors, and can be used as motor-wheels in transportation vehicles and in other technologies. The aim of the present invention is to provide an electric motor with increased performance characteristics, relatively simple design, and high reliability.

Abstract: An electric motor intended for driving transport vehicles without a reduction gear is described. The electric motor can have an annular magnetic conductor of the stator with permanent magnets located on opposite sides of the magnetic conductor, and a two-section rotor, one section of which goes round the stator, while the other is inside it. The electric motor provides greater torque.
Abstract: An electric motor includes a stator which carries permanent magnets, and a rotor which carries electromagnets. A particular arrangement of connecting up the windings of the electromagnets to the distributing collector and the selection of the ratio of stator magnets to rotor electromagnets enable higher torque to be achieved. The main field of application is in motor-wheels of vehicles.
