Our EV electric motor technology is unsurpassed in performance, efficiency, and reliability.
. Full Load Torque at 2500 rpm
- Same performance at much lower rpm than typical electric motors
- Simplifies engineering and materials requirements
. Higher Efficiency
- Motor runs at >98% efficiency in operating range
- Significantly more efficient than any EPA reported rates of other EV motors
Extended Range
- Higher efficiency translates into an extended range
- Provides the option to alternatively reduce the battery pack
Reliability
- Lower motor speed and less heat generated improves reliability
- Unique coil design eliminates the risk of catastrophic motor failure
Eliminates Need for Transmission
- Low rpm allows for direct drive configuration without the need to gear down from high rpm
- Eliminates cost, weight, and maintenance of a separate transmission
Radial-Axial-Radial Design
Our patented electric motor has three magnets positioned on the rotor in a Radial – Axial – Radial configuration.
This design creates three magnetic fields and three precisely controlled air gaps, which provides significant performance advantages.
The design produces high power density, high efficiency, and extraordinary torque and power production, regardless of load, throughout the operating range beginning at very low speeds.
Instead of conventional field windings, our electric motor is constructed with multiple removable coil/ferromagnetic core modules.
The modular coil design contributes to significant thermal efficiency, regardless of whether passively air cooled or actively liquid cooled, which further increases operating range and contributes to longer machine life
Highly Efficient
The three magnetic fields and three resulting air gaps all working synergistically result in >98% efficiency across the operating range.
This results in high torque, high power density, and high efficiency.
The map of magnetic flux density shows the three field design operates without saturation (i.e., efficiently without losing flux).
Multiple Drive Train Configurations
Because our motor dispenses with a mechanical transmission, it opens up previously impractical or impossible drive train design possibilities. Here are three basic design configurations.
Configuration #1: One Motor Per Axle
The resulting design would deliver:
- 200 mph at a motor speed of <2,500 rpm
- >250 HP per motor
- >750 Nm of torque per motor
- The weight of each motor would be <115 lbs
- Assumptions: 21” wheel, 27.8” tire, 18” motor, 8” in length
Configuration #2: Two Motors Per Axle
The resulting design would deliver:
- 200 mph at a motor speed of <2,500 rpm
- >250 HP per motor
- >750 Nm of torque per motor
- The weight of each motor would be <115 lbs
- Assumptions: 21” wheel, 27.8” tire, 18” motor, 8” in length
Configuration #3: Four Hub Motors
Although our technology provides superior performance in centrally located drive trains it can also be adapted to four direct drive hub motors, one on each wheel
The resulting design would deliver:
- 200 mph at a motor speed of <2,500 rpm
- >250 HP per motor
- >750 Nm of torque per motor
- The weight of each motor would be <115 lbs
- Assumptions: 21” wheel, 27.8” tire, 18” motor, 8” in length
