Different motors have different requirements for permanent magnets.
For motor ferrite arc magnets, some adopt 8-piece splicing, some use 10 pieces, and others with more segments.
There is a common misunderstanding:
Does more magnet pieces bring higher motor torque?
Actually, more magnet pieces do not equal higher torque.
The more arc magnet segments on the rotor, the closer it is to a perfect circle, making the air gap more uniform.
It ensures smoother magnetic field transition, more stable motor operation, even torque output, and lower vibration & noise.
Motor torque is generated by the combined action of
rotor magnet field and stator coil field:
✅ Magnet performance: Depends on ferrite grade (Y30/Y35/Y40), magnet height and thickness
✅ Stator performance: Determined by silicon steel material, coil turns and slot filling rate.
More coil turns and full copper winding deliver higher torque under the same current.
The number of magnet segments mainly affects
pole pairs, running stability, noise and speed characteristics,
it does not directly determine motor torque.
Pole pair design is mainly for adjusting low-speed and high-speed performance,
not simply relying on more magnet pieces for stronger power.
Low pole pair motors usually use arc tile ferrite magnets,
which perfectly fit rotor structure, optimize air gap, reduce magnetic leakage,
and improve overall motor efficiency, not only focusing on high torque.
