Abstract:
A magnetically journalled electrical drive comprising:a magnetically journalled electrical machine having a rotor and a stator;the stator for the production of the torque and the suspension force of the rotor relative to the stator, the stator having at least four windings;the rotor suspended magnetically relative to the stator and producing magnetic flux; and,an electronic circuitry for control, regulation, monitoring and excitation of the stator having communication to the windings having three variable electrical components with at least one component responsive to driving the rotor relative to the stator and at least two components for suspending the rotor relative to the stator, the variable electrical components dynamically varying with respect to the windings of the stator to produced controlled suspension and controlled torque of the rotor relative to the stator.
