  • Direct Drive Hub Motor

For vehicle propulsion purposes the high torque motors of Magnetic Innovations are perfectly suited to function as a hub motor. In the direct drive hub MI-HT (bike) series the magnetic design is optimized to reach the highest torque output available in the market today. Two versions with different torque capability are available. Please see the data sheet in the publications tab.

The outrunner motor concept enables a seamless integration of the motor into the hub of the wheel. Moreover, the control of the hub motor is ideally suited for sensor-less control for further cost saving and increased reliability. The control electronics is highly efficient and is located outside the hub motor housing. Furthermore, the current control is based on space vector modulation to make full use of the available supply voltage .

For series production the hub motor design is adapted for automated winding in order to minimize production costs. Thereafter, the so called cogging of the motor, that is associated with permanent magnet motors, is minimized without the traditional and cost increasing skewing of the stator lamination.

Key features:

  • Direct drive, no transmission gears
  • Highest torque density
  • High efficiency
  • High reliability and lifetime
  • Quiet operation
  • Maintenance free
  • Cost efficient design
