Brushless motor rotor shell magnets steel fall off cause? How to prevent the rotor magnets from falling off?

Many brushless motors are external rotors with magnets affixed to the housing, such as brushless model motors, sometimes due to various reasons, resulting in magnet shedding, demagnetization, running weakness and other phenomena, why is this? How to avoid the rotor shell magnets off? The following Vacuz to give you an introduction to it!

Rotor shell magnets fall off for the following reasons:

1. Brushless motor magnets can not be violently struck or bumped to prevent demagnetization.

2. Magnets also can not be out of the open state for a long time, should be stable paste in the shell, forming a circuit, otherwise it will also demagnetization.

Generally speaking, the impact of the magnet off on the operation is not too big, mainly is the running speed will be slowed down accordingly, and more power consumption, such as electric car demagnetization is this reason.

How to prevent the brushless motor rotor magnets off: 1:

1. If it is a piece of magnet off, you need to follow the original magnet, first brush glue, put a piece in, to ensure that the magnet N, S pole correct, and other magnets flush, to ensure that the brushless motor air gap and mechanical size the same.

2. If it is rotor magnet manufacturing, you can use special magnet loading equipment, first dot glue or brush glue, you can use better anaerobic glue, and then use the equipment to load the magnets, once loaded, sticky and stable, and then start assembling.

Brushless motor rotor shell magnets fall off cause? How to prevent the rotor magnets from falling off? The above has made a simple explanation, I hope these tips can help you!
