Direct-drive technology
20x faster wheel control than conventional e-drives
• Full torque delivery in 4 ms
• 100x bandwidth sensing of torque, position and speed @10kHz
• Rapid torque adjustments >500 Nm/ms at tyre-to-road contact
500Nm & 50kW to 6000Nm & 500kW per wheel
Scalable in-wheel motor design
Patented active part technology in 24 patent families
- Continuous hairpin/wave winding topology
- Torque mass density up to 130 Nm/kg of active part
- Torque volumetric density up to 620 Nm/liter of active material
- Very efficient thermal management – 75 W/K heat dissipation coefficient
- Current density of up to 65 Arms/mm^2
Optimized structural parts and layout:
- Motor parts only carry their own weight and transfer torque
- Sharing components, i.e. bearings and knuckles reduces added weight

High-speed control solutions
01. Elaphe Motor control – system weight, efficiency and cost optimization
High resolution motor control with dynamic control strategies that optimize performance, efficiency and comfort (Noise Vibration Harshness) targets.
02. Elaphe Slip control - instant-response road contact manipulation
Actively adjusts torque and power to each independent wheel to prevent excessive wheel spin or loss of traction. For significantly improved performance and reliable grip with natural feel on any surface.
03. Elaphe Vertical Motion Control - precise vehicle body control in 6 degrees of freedom
Utilizes vertical suspension reaction force caused by applied motor torque to finely control the motion of the whole vehicle without additional actuators. For superior stability and maximum comfort.
04. Elaphe Vibroacoustics - authentic motor sound and vibration control
Inverter software controlling airborne and structure-borne sounds and vibrations of in-wheel motors for signature sound and feel. Completely smooth and silent or amplified and customized for emotion and brand identity.
Elaphe technology carrier vehicle
• Motion control and vehicle dynamics development platform
• All-wheel drive with direct-drive in-wheel motor in every wheel
• State-of-the-art Elaphe high-speed control features
It’s not a question of IF anymore – the engineering and economics of in-wheel motors hold up – it is a question of WHO and HOW. We believe our in-wheel motors and high-speed control solutions offer a unique combination of cost advantage and driving emotion that no other solution delivers.”
