Due to issues such as the need for fast and accurate loop control and the number and cost of components required to perform intelligent motor control through digital power management, these controls It sets the standard for motor control applications that must provide best-in-class performance and a rich set of comprehensive advanced features to simplify closed-loop control design in general-purpose motor control.
In recent years, microcontrollers () specially used for motor control have come out, integrating bit calculation engines, analog-to-digital converters (), comparators, counters, timers and other circuits to control the motor speed to meet the load power requirements. Due to fast and precise closed-loop control and the low number and cost of required supporting components, this controller sets new standards in terms of expectations. The problem faced by manufacturers is how to ensure that the appropriate external components and features are integrated while still keeping the price of the product attractive to consumers.

A best method
The figure shows a low-cost and efficient digital power management solution for advanced motor control, especially general motor control applications. The on-chip analog peripherals are developed and integrated into one of its components.
Main functions of motor control
This particular digital power management solution provides the main control functions required for general-purpose motors: soft start, over-current fault protection and the use of on-chip comparators to determine the AC circuit zero-crossing point and Ability to ensure synchronization of output signals. Let's break it down one by one and see how this solution meets these requirements:
Soft Start
The soft start function ensures that power is gradually delivered to the motor when it is turned on. Adjustable control is achieved by using the single/output to control the trigger/ignition angle of R. This feature minimizes the overshoot and jerky movement of the rotor during startup, thereby reducing motor wear, preventing sudden changes in demand, and avoiding the situation where a circuit break causes all electrical appliances that have just been turned on or are running to be shut down.
The soft start implementation method uses a timer and a lookup table used when reloading the high and low bytes of the timer. Twenty evenly distributed firing angles can be achieved within one half cycle of the AC signal. In this way, the R firing angle can be adjusted (as shown in Figure 3) to adjust the power delivered to the motor. This soft-start scheme uses a microsecond output pulse width to trigger R, during which the trigger angle rises from to (one half-cycle to), at which point the motor transitions to normal full speed operation.
