Abstract
FF-180SH is a mini type permanent magnetic current motor. IT adopts cheap magnetic ferrite as the energizing source. The batteries was chosen as the power source, its export nominal power is 0.4V,nominal nominal speed of revolution is 4800r/min. The parts of the electronic machine are machined by mould, and they are available for batch production to lower the costs.
Small volume, lightly weight, simple structure are the main characteristic of the motor. And the top of the efficiency of the motor can reach 67.5%.
It is widely used shavers, aviation mold, and all kinds of family using electronics.
Key words: FF-180SH permanent magnetic current motor magnetic ferrite
