This solution uses the Infineon motion control chip IMM101T to drive the motor. Through precise control algorithms, the motor can reach a high speed of more than 100,000 revolutions, which has the advantages of high efficiency and low noise. The chip has a built-in controller, driver and power device, which is highly integrated and simplifies external devices to the greatest extent, which not only enhances the anti-interference ability of the system but also reduces the cost.

The IMM101T chip already contains the MCE motor control algorithm firmware. By setting the parameters of the motor and hardware, the motor can run quickly and smoothly, which greatly shortens the development cycle.
