Features

SR Motor

The complete novel motor is based on the principle of the switched reluctance motor (SR = switched reluctance). The stator is very robust but simple. The rotor exists of a shaft on which there are strung several single steel laminations. This allows the motor to work without any turning windings or short circuit rotor and also without commutator and wear-affected carbon brushes. The motor saves resources, it consists almost only of steel and copper.
The commutation (alternating currenting of the stator poles) is managed by the electronic power which gets its orders from a microcomputer. The spe
