Achieving Smooth and Fast Startup of a Sensorless BLDC Motor Using a Microcontroller for Sensorless Initial Position Detection

White Paper

Brushless DC motors featuring low noise and high durability are extensively used in many fields, including industrial applications, automobiles and household appliances.

This paper describes a method for initial rotor position detection that is realized by using a microcontroller for motor control and is highly useful for the control of such motors. This method solves various problems that tend to occur with sensorless motors, making it possible to realize a highly efficient system with smooth and fast high-torque startup.
