48V Black Three Phase Brushless Motor 250W 1000 - 4000 Rpm For CNC Machine'
BLDC motors have found wide application in various industries - from computer hard drives to electric transport and industrial robots. In some fields, they have almost squeezed out brushed DC (BDC) motors. High performance and durability are among the major advantages of a brushless DC motor. Nevertheless, it will hardly edge out BDC motors completely as it is still a costly solution with a complex construction and control system. A BLDC motor controller can perform the same functions and apply similar methods as a brushed DC motor controller. However, there are some conceptual differences in their arrangement and implementation. This article will shed light on the characteristics of a brushless DC motor controller, that is how it works, how it is built, and what it works best for.

Ideal Applications for BLDC Motors
We’ve seen that BLDC motors offer high efficiency and controllability, and that they have a long operating life. They are widely used in devices that run continuously. They have long been used in washing machines, air conditioners, and other consumer electronics; and more recently, they are appearing in fans, where their high efficiency has contributed to a significant reduction in power consumption.
They are also being used to drive vacuum machines. In one case, a change in the control program resulted in a large jump in rotational speed—an example of the superlative controllability offered by these motors.
BLDC motors are also being used to spin hard disc drives, where their durability keeps the drives operating dependably over the long term, while their power efficiency contributes to energy reduction in an area where this is becoming increasingly important.
