A Better Way To Travel

Our innovative in-wheel motor technology generates power directly in a vehicle’s wheels.

The electric vehicle revolution has grown out of conventional vehicle design. It made sense to start the shift to electric power with traditional single, central motor and drivetrain technologies. But electric power creates opportunities to innovate.

By moving power to the wheel, we have created a technological leap forward. Our paradigm shift gives drivers improved torque response, enhanced handling, faster acceleration, less charging and greater range. It offers manufacturers a simplified assembly or conversion process.

Our ProteanDrive in-wheel motors have integrated power electronics and digital control. Direct drive means no gears are required, and by partnering with leading brake system experts we have developed friction brakes that suit any type of vehicle.

Clear Benefits

Our in-wheel technology offers a wide range of benefits for manufacturers, fleets, drivers and passengers:

Manufacturers

For manufacturers our technology delivers design freedom and production efficiency. Without driveline components compromising vehicle space, they are free to develop exciting new vehicles that reflect their customers’ lives and needs. And with fewer components comes a simpler, cost-effective production process and a more efficient supply chain.

Fleets

For fleets, our in-wheel technology means a simpler, cost-effective conversion to electric power with minimum disruption to business. As cities increasingly control vehicle access, it delivers dramatic emission reductions and acts as a passport to the clean cities of the future.

Drivers

For drivers searching for longer range electric vehicles with better handling it means freedom, enjoyment, choice and economy.

Passengers

Self-driving vehicles and Robo-taxis are not far away. Using ProteanDrive, imagine vehicles you walk into with family, luggage and pushchairs, designed to travel safely in space and comfort, and that park by moving sideways.

WHAT THIS MEANS

Drive Longer

In-wheel motors remove efficiency losses associated with gear, differential and CV joints situated around the vehicle. Total vehicle weight is also reduced.

This means:

  • Greater range
  • Reduced running costs
  • Lower charge frequency

Better Handling

Individual wheel motors provide torque distribution to different wheels (torque vectoring)

This means:

  • Improved driver handling
  • Enhanced stability and control
  • Improved traction control
  • Shorter stopping distances

Creative Freedom

In-wheel motors revolutionize car design. No requirement for existing driveline components means car design is no longer compromised.

This means:

  • Flexible vehicle design
  • Flexible manufacturing process
  • Simpler development of hybrids

Production Efficiency

In-wheel motors with integrated inverters do not require a gear, differential, drive-shafts or external drive electronics.

This means:

  • Comparable system cost
  • Reduced development cost
  • Lower manufacturing cost
  • More opportunity for modularity

ProteanDrive

Our ProteanDrive product offers high power and torque density. Designed to maximise efficiency and simplify the vehicle production process, all of our models are in-wheel motors with integrated power electronics and digital control, packaged with a compatible friction brake.

Developing a tried and tested product hasn’t always been a smooth journey. We’ve faced and overcome important technical issues and helped our industry to rethink some long-standing misconceptions.

We have found ways to integrate brake systems, keep closely packaged electronics cool, keep water and dirt out and simplify communication between individual components and wheels. We have developed technologies to withstand a 300,000 kilometre vehicle lifetime, which includes shock and vibration, pot-holes and kerb strike.

OVERCOMING THE CHALLENGES

  • Unsprung Mass

    Perhaps our longest standing challenge has been overcoming the perception of “unsprung mass”. We have demonstrated that increasing wheel weight needn’t impair handling, comfort and safety. Independent tests have proved “unsprung mass” is no limitation to in-wheel technology.

  • Integration Of Friction Brake

    Working with Alcon, we have integrated and packaged a foundation brake within the motor that matches standard vehicle performance and has been successfully validated on a variety of vehicles.

  • Thermal Management

    Cooling multiple electronic subsystems effectively has been achieved by our patented cooling design.

  • Ingress Protection

    Protecting internal motor components from water and debris in a harsh in-wheel environment has been achieved to the lifetime of a vehicle

  • Vehicle Control

    Our vehicle control software makes individual wheel control achievable in existing vehicle architectures.
