Halbach rotor

Every component is designed for maximum performance & reliability including the rotor.

Halbach array

Alva’s state-of-the-art Halbach array rotor maximise the magnetic field density

Composite sleeve

A composite sleeve assures failure free operation in any condition

Large OD/ID ratio

Alva’s slotless motor technology results in a thin stator & rotor compared to both slotted motors & other slotless motors, allowing a large inner diameter of the rotor. Other components, for example gears, can more easily be placed inside the frameless motor, to increase overall system compactness.
