Embedded Solution for Brushless DC Motor Control

摘要

Lrushless direct current motors (BLDC) are a type of LDC motors that do not use brushes for commutation but are electronically commutated. Since BLDC motors do not use brushes they have longer operating life and noiseless operation. For BLDC motors the ratio between the torque and the size of the motor is high. This feature makes BLDC motors suitable for applications where space and weight are critical. Some other characteristics of BLDC motors include higher speed, better speed versus torque characteristics and high dynamic response. They are used in several industry fields: appliances, automotive, aerospace, consumer, medical, industrial automation equipment and instrumentation.
