Introduction of bonded Chin-iron-boron circular magnets for brushless motors in Yundai

The bonded Chin-iron-boron circular magnets is a permanent magnet steel, relying on changing the alternating frequency and waveform of the current wave input to the stator coil of the brushless motor, forming a magnetic field around the winding coil rotating around the geometric axis of the motor, this magnetic field drives the permanent magnet steel on the rotor to rotate, and the motor turns. especially nowadays, the brushless motor has the advantages of brushless, low interference, low noise, smooth operation, long life, low maintenance cost, etc. than the brushed motor.
As the market positioning is high technology on high profit, the performance of the motor and the number of magnets, magnetic flux strength of magnets are closely related, so small and medium capacity brushless DC motor permanent magnets began to prevail. but the magnets are also divided into different schools: some take the general route, that is, the use of ferrite magnets, while some take the high-end route, the use of bonded Qin iron boron ring.

Bonded iron boron single wall thickness can be achieved about 1mm, some customer demand is mostly about 1.5mm. bonded iron boron salt fee experimental test ≥ 72 hours, and the maximum working temperature of 150— 150 ° C. products once formed, without secondary processing, can be directly made into a variety of complex shapes. bonded iron boron magnetic in all directions, coupled with the general bonded iron boron commonly used surface treatment for electrophoresis epoxy, so bonded iron boron magnets have high precision, strong magnetic properties, corrosion resistance, high temperature performance advantages. because the head model is more or less the same, different in so little size, it may lead to a fallacy of a thousand miles, may have to process iron boron compression mold and injection mold
