PTZ brushless motor magnet - Bonded NdFeB Magnetic Ring

 

The rotor of the brushless motor of the gimbal is a permanent magnetic steel, relying on changing the alternating frequency and waveform of the current wave input to the stator coil of the gimbal brushless motor, a magnetic field that rotates around the geometric axis of the motor is formed around the winding coil , this magnetic field drives the permanent magnet steel on the rotor to rotate, and the motor starts to rotate. Especially nowadays brushless motors have the advantages of brushless, low interference, low noise, smooth operation, long life and low maintenance cost compared with brushed motors.

Bonded NdFeB Magnetic Rings-1

Since the market positioning is high-tech and high-profit, the performance of the motor is closely related to the number of magnets and the flux strength of the magnets, so the permanent magnets of small and medium-capacity brushless DC motors have become popular. But magnets are also divided into different genres: some take the general route, that is, use ferrite magnets; while some take the high-end route, using bonded NdFeB rings.

 

It is reported that the wall thickness of one side of bonded NdFeB can be about 1mm, and the specifications required by some customers encountered by our company are mostly about 1.5mm. Bonded NdFeB salt spray test ≥ 72 hours, and the maximum working temperature is 150-180 ℃. The product is formed once, without secondary processing, and can be directly made into various complex shapes. Bonded NdFeB magnets are magnetic in all directions, and the commonly used surface treatment for bonded NdFeB magnets is electrophoretic epoxy resin, so bonded NdFeB magnets have high precision, strong magnetic properties, and strong corrosion resistance. Advantages such as high temperature performance.

 

Because the models of the gimbals are similar, the main difference lies in the size, and it may be necessary to process NdFeB compression molds and injection molds. The Division provides professional free consulting services.
