Arc segmented ferrite for motors is a common magnetic material with the following main features;
The ferrite magnet is made into an arc-shaped structure, which is divided into multiple arc segments according to a certain pole spacing.
Each arc structure is equivalent to a magnetic pole, and multiple poles form a multi-pole magnetic ring.
The arc-shaped design is in line with the structure of the motor cylinder, which is conducive to improving the utilization of magnets.
Segmented structure can reduce the turn-to-turn cross slot, reduce magnetic leakage phenomenon.
Ferrite is inexpensive and can be used to produce large-size curved structures to provide sufficient magnetic flux.
With optimized design, iron loss can be controlled at a low level.
Good thermal stability, suitable for motors with large heat generation.
It can generate large attraction with the rotor core to provide stable torque output.
It is a kind of low cost and reasonable performance motor magnet choice.
In summary, the curved segmented ferrite ring structure is simple, practical, cost-effective, and widely used in various types of motors.
