Brushless DC Motors Overview

Brushless DC Motor ConstructionMade possible by the development of solid-state electronics in the 1960s, the brushless DC motor, or BLDC motor, is a type of synchronous electric motor that a DC power source powers. Conventional BLDC motors are available in a variety of configurations. Among the most popular are those that look like brush-type motors. The difference is that brushless motors use a wound stator that surrounds a permanent-magnet rotor—an arrangement that’s inverse from that found in brush motors. In BLDC motors, stator windings are commutated electronically instead of using a conventional commutator and brushes.

Windshield wipers, CD players and power windows in vehicles all use BLDC motors. More recently, the desire for alternative-fueled vehicles has breathed new life into the design and availability of hybrid and electric vehicles, as well as the high-tech motors that power them. Brushless DC motors are commonly used in electric vehicles of all types because of:

  • Their high efficiency
  • Low maintenance
  • Operating speeds
  • Lack of sparking
  • Compact size
  • Quick response

HVAC and Refrigeration

In the HVAC and refrigeration industries, BLDC motors are becoming the norm over the typical AC motor. The top reason for the switch is the reduction in the power required to operate the motor. HVAC and refrigeration engineers also like how brushless motors add to a system’s overall efficiency and install them in many fans.

Manufacturing & Industrial Engineering

Manufacturers use BLDC motors for positioning, actuation systems and more. The motor is considered ideal for several manufacturing application and is commonly used industrial automation design.

A few of the motor’s aspects that manufacturing companies and engineers praise include its:

  • Power density
  • Good speed-torque characteristics
  • Speed ranges
  • Ease of maintenance

Motion Control Systems

BLDC motors are often preferred in motion-control applications as their benefits outweigh potentially higher costs. When it comes to energy-, maintenance- and downtime-related costs, brushless DC motors may cost less than brush types in some applications.
