This is a multi-pole magnetic ring specially used in DC fan motors, according to the different needs of customers, the size is also large and small, the number of poles commonly used radial 8 pole, 10 pole, 12 pole, 14 pole, 16 pole, etc., is made of multiple pieces of high-performance grade sintered arc ferrite magnets combined with ABS plastic, compared to the traditional single piece of arc ferrite magnets, more easy to install, such as consulting the price of please provide the For price inquiry, please provide the required outer diameter, inner diameter, height dimensions, as well as the number of magnetization poles, gauss requirements, and so on.
The picture below shows a 14-pole fan motor ring with an outer diameter of 96.5mm, an inner diameter of 86.5mm and a height of 27.5mm.
Similar to fan motor magnets;
BLDC ceiling fan motor magnet ring 153 x 135 x 34 mm
Ceiling fan magnetic ring internal 10 poles 65.5 x 57.5 x 20 mm
