What happens when the positive or negative pole of a permanent magnet motor contacts a magnet tile?

When the positive or negative pole of a permanent magnet motor contacts a magnet tile, the magnetic field and the tile itself change. Specifically:

Magnetic field change:

• The magnetic tile directly affects the magnetic field of the permanent magnet, causing the entire magnetic field layout to change.
• This magnetic field change can further affect the performance of the permanent magnet motor, for example, significantly reducing output power and efficiency.

Magnetic tile change:

• As a magnetic material, the magnetization of the magnet tile changes when it contacts the positive or negative pole of the permanent magnet motor.
• The change in the magnetic tile field also has a negative impact on the permanent magnet motor, affecting its output power and efficiency, potentially leading to unstable or reduced motor performance.
