Electronica has been researching 3-phase and 5-phase magnetically geared motors. These motors have a wide range of applications. Initially, we are concentrating on pump applications with a view to using the new motors in place of the currently used induction motor pumps. There is great interest in these products due to the savings that can be made on energy bills, compared with normal induction motor pumps. Aerospace applications will be the target market for the 5-phase motors. These 5-phase motors are smaller, lighter in weight and have higher power densities than 3-phase motors.

In the coming years, more stringent environmental legislation can be expected on a world-wide scale.  This will demand a reduction of fossil fuel usage in order to limit its consumption and control the emissions of greenhouse gases. Our efficient variable speed motors will be ideal replacements for the many inefficient motors currently in use.

The initial design will be particularly suitable for pump applications in the aerospace, consumer and possibly automotive markets. The flexibility of the variable speed and torque characteristics of the motor will provide appliance manufacturers with the opportunity for utilizing a highly efficient motor, which is both compact and light and does not require an additional gear box.
