White drone motor close up on a black background

Permanent magnet motors are electric motors using permanent magnets in addition to windings.  Such motor designs are more efficient than induction motors or motors with field windings for certain high-efficiency applications such as electric vehicles and small electric motors such as found on drones and in car windshield wipers. Both AC and DC motors benefit…

Bunting Magnetic Assembly

Halbach Arrays feature in many common-day devices such as brushless DC motors and even the Inductrack Maglev train. The Halbach Array is a specific arrangement of permanent magnets that cancels the magnetic field to nearly zero on one side, but significantly increases the strength of the magnetic field on the opposite side. This magnetic phenomenon…

Magnetic Rotor Combo

Magnetic rotors are used in a wide range of applications including motors, generators, alternators and Eddy Current Separators. These rotors spin at very high speeds and a key design consideration is ensuring that the motors do not become detached from the magnet carrier. One of the key design considerations is the resultant centrifugal force. Centrifugal…
