Magnet Sheet Quality

Here you can see how the magnet sheets are assembled into the motor.

I have two magnet sheets in my hand.

At first glance, they look almost identical.

But the difference is huge:

One can withstand 120°C,

The other only 100°C.

Once the temperature goes above 100°C, the weaker magnet will start to lose its strength.

This directly affects the motor’s durability, service life, and power efficiency.

So even if two motors are both “70-magnet motors,”

if they use different quality magnet sheets,

the actual performance can be completely different.
