In the previous article, we have introduced the performance of curved (arc) magnets directly affect the efficiency of the motor, and today we will introduce the length, width and thickness of curved magnets, and whether the arc has an impact on the motor.

Size of the curved magnet has an important effect on the performance of the motor. The following are some general effects of size parameters on motor performance:

1. Length of arc magnet: The length of the magnet can affect the magnetic field strength and magnetic flux of the motor. Longer magnets can provide a larger magnetic field, which increases the output power and torque of the motor.

2. Width of arc magnet: The width of the magnet also affects the strength and flux of the magnetic field. A wider magnet can provide a larger magnetic field area, thereby increasing the output power and torque of the motor.

3. Radian of arc magnet: The arc of the magnet determines the number of pole pairs and pole distance of the motor. Polar pairs refer to the number of North and South poles on a magnet, while polar distance refers to the distance between adjacent North and South poles. A larger number of pole pairs and a smaller pole distance can increase the smoothness and accuracy of the motor's output.

4. Thickness of arc magnet: The thickness of the magnet has an impact on the magnetic field distribution and magnetic resistance of the motor. Thicker magnets can provide greater magnetic field depth, thereby increasing the magnetic field stability and efficiency of the motor.

For different types of motors (such as DC motors, AC synchronous motors, stepper motors, etc.), different size parameters may have different effects. Therefore, when designing motors, it is necessary to comprehensively consider multiple factors and conduct detailed design and optimization to achieve the required performance requirements.
