What determines the lifeexpectancy of a Brushed DC motor? Typically, the brushes are the limiting component in a Brush DC motor's lifeexpectancy. The lifeexpectancy of the brush is dependent on application parameters such as torque, speed, duty cycle and
What determines the lifeexpectancy of a Brushless motor? The life expectations of a BLDC motor are dependent on the operating conditions and environment. Under “ideal” conditions, a BLDC motor-only will have minimal wear and will have a long life span.
