Abstract
An electric motor includes one or more separate coil sets arranged to produce a magnetic field of the motor. The electric motor also includes a plurality of control devices coupled to respective sub-sets of coils for current control. A similar arrangement is proposed for a generator. A coil mounting system for an electric motor or generator includes one or more coil teeth for windably receiving a coil for the motor and a back portion for attachably receiving a plurality of the coil teeth. A traction control system and method for a vehicle having a plurality of wheels independently powered by a respective motor. A suspension control system and method for a vehicle having a plurality of wheels, each wheel being mounted on a suspension arm of the vehicle and being independently powered by a respective motor.

A traction control system for a vehicle comprising a plurality of wheels, each wheel being independently powered by a respective motor, the control system comprising:
- sensors for detecting an acceleration in the rotation of each of the wheels;
- and
- a control unit for adjusting a torque applied to each wheel by each respective motor in response to detecting a predetermined acceleration in the rotation of one or more of the wheels, wherein the predetermined acceleration is indicative of a skid.
A traction control method for a vehicle comprising a plurality of wheels, each wheel being powered by a separate motor, the control method comprising:
- detecting an acceleration in the rotation of one or more of the wheels;
- and
- adjusting a torque applied to each wheel by each respective motor in response detecting a predetermined acceleration in the rotation of one or more of the wheels, wherein the predetermined acceleration is indicative of a skid.
A coil mounting system for an electric motor, the system comprising:
- one or more coil teeth for windably receiving a coil for the motor;
- and
- a back portion for attachably receiving a plurality of said coil teeth.
A coil mounting system for an electric generator, the system comprising:
- one or more coil teeth for windably receiving a coil for the generator;
- and
- a back portion for attachably receiving a plurality of said coil teeth.
A method of manufacturing an electric motor, the method comprising:
- providing a coil for the electric motor onto a coil tooth;
- and
- attaching the coil tooth with coil to a back portion that is arranged to receive a plurality of coil teeth.
A method of manufacturing an electric generator, the method comprising:
- winding a coil for the electric generator onto a coil tooth;
- and
- attaching the coil tooth with coil to a back portion that is arranged to receive a plurality of coil teeth.
An electric motor for mounting in a wheel for a road vehicle comprising:
- a stator having a plurality of coils;
- a rotor having a plurality of magnets surrounding the coils of the stator;
- a radial wall of the stator having a central region for mounting to a vehicle on one side and for connection to a bearing block;
- a radial wall of the rotor having a central region for mounting a wheel on the outside and to the bearing block on the inside;
- and
- wherein a wheel may be mounted to the motor at the central portion of the wall of the rotor for connection to a vehicle by the bearing block.
