The actuator makes use of the effect that electricity, within an appropriately cooled superconductor, is transmitted without loss. This makes it possible to generate a strong magnetic field with very high currents. The SupraMotor has extensive overload capacity and is suitable for applications which are run in continuous operation. Thanks to the resistance-free superconducting coils, it’s also almost impossible for it to overheat.
The motor works particularly efficiently at low speeds with very high torques. If a load has to be held, no energy is consumed by the actuator even at maximum holding torque. Overall power requirements are low as well: whereas the motor’s output power is in the double-digit kilowatt range, it only needs energy for cooling in the low three-digit watt range.
