Samarium Cobalt (SmCo) magnets, of the Rare Earth class, have been available since the early 1970’s.
These magnets possess very high magnetic properties, excellent thermal stability, while remaining resistant to corrosion. These characteristics make SmCo magnets ideal for applications requiring a resistance to wide-ranging temperatures and environments.

SmCo magnets are manufactured by sintering or compression bonding. They are anisotropic and can only be magnetized in the direction of orientation. In general, magnetizing fields of approximately 30 to 45KOe are required to saturate SmCo magnets.

Motors within the AC motor classification are either synchronous or asynchronous, primarily distinguished by the speed of the rotor relative to the speed of the stator. The speed of the rotor relative to the stator is equal in a synchronous motor, but the rotor speed is less than its synchronous speed in an asynchronous motor. In addition, synchronous motors have a zero slip and require an additional power source, while asynchronous or induction motors do have slip and do not require a secondary power source.

Generator Rotor SmCo Magnet for Permanent Magnet AC Motors

A synchronous motor is a doubly excited machine, meaning it includes two electrical inputs. In a common three-phase synchronous motor, one input, usually three-phase AC, supplies the stator winding to produce three-phase, rotating magnetic flux. The rotor supply is usually DC, which excites or starts the rotor. Once the rotor field locks with the stator field, the motor becomes synchronous. Industrial PMDC Motor Arc SmCo Magnet
