Genochi brushless motor is a device that combines the mechanical structure and brushless motor driving technology of the Gongtai.Its working principle is similar to that of ordinary brushless motors, but it is added with a mechanical structure and can be used to carry and rotate cameras, telescopes and other equipment to achieve stable shooting and observation.

The bearings of the brushless motor usually use the sliding bearings or ball bearings to support the device to achieve smooth rotation.At the same time, the brushless motor can passControllerThe encoder controls position and posture.If you need to operate more stable, you can also install a gyroscope.

The working principle of a brushless machine is based on the principle of electromagnetic induction and the principle of electromagnetic inductionElectronic technology, That is, the magnetic field of the stator generates a magnetic field to drive the rotation of the rotor.Generally, there are three stator and one rotor of the brushless motor. Each stator has several coils, and the adjacent poles of the coil have a magnet.

Brushless motors and brush -free motors are both efficient, low -noise, low failure motors, which are widely used in industrial, aviation, medical and other fields.The working principle of a brushless motor is to drive a magnetic field through the alternation of the stator to drive the rotor, and the brushless motor of the gimbal brushless motor combines the brushless motor with the mechanical structure to achieve smooth rotation.

DC brushless motor driver chip -SS6343M, a three -phase brushless DC motor drive.Its working voltage range: 3V ～ 16V; guideresistanceOnly 140mr; 3mmx4mm QFN packaging provided 24-footed foot, with exposed heat sink; the chip integrated three half bridge, including six N dites power MOSFETs, and front drives, grid drive power supply; for each ½--The H bridge provides enable pwm input.

The SS6343M can continue to provide a 2A driver current (depending on temperature and PCB conditions), and the peak of the current protection threshold can reach 7A.It uses the internal charge pump to generate a gate -drive power supply voltage for the high -voltage side MOSFET, and use the trickle chargingCircuitKeep enough grid driving voltage to work at a 100%duty ratio.

Internal integrated security protection functions include heat shutdown, under pressure lock (UVLO) and over -current protection (OCP).The SS6343M provides a 3mmx4mm QFN package with a 24 -footed foot, with exposed heat sink.
