From aerospace to e-mobility, marine propulsion to renewable energy, magnetically geared motor technology is redefining what’s possible in power transmission and drive systems.

Magnetically geared motors outperform traditional mechanically geared systems in terms of energy efficiency. By imitating the attributes of a direct drive, they can deliver high torque at low speeds, surpassing the thermally limited torque generation limits of traditional direct-drive electric motors.

Additional efficiency gains come from having no mechanical friction and low electrical current; as heat output is limited, the need for energy-consuming cooling is minimised.
