High performance Multi Half-Bridge Motor Driver for Intelligent Motor Control in Stock

When the motor of the brushless motor driver rotates, the control unit must first determine the order of opening (or closing) the power transistors in the converter according to the position of the motor rotor sensed by the hall-sensor, and then according to the stator winding, AH, BH, CH (these are called upper arm power transistors) and AL, BL, CL (these are called lower arm power transistors) in the converter, Make the current flow through the motor coil in order to generate a clockwise (or reverse) rotating magnetic field and interact with the magnet of the rotor, so that the motor can rotate clockwise/counterclockwise.

The servo motor driver has low cost and excellent performance, so it is the mainstream low-power motion controller. It has reached or even surpassed the AC servo system in terms of accuracy, noise, speed and low speed stability, and is widely used in industries such as spray painting, small and medium-sized engraving, electronic processing, digital control machine tools, packaging equipment, textile printing, etc. The effect is particularly good when it is used in equipment with minimal vibration, ultra-low noise and high speed that users expect.
