Advantages of Brushless DC Motors

  • High performance and efficiency - BLDCs are broadly more efficient than their brushed counterparts. They use electronic capabilities, allowing for fast and precise control of the speed and position of a motor.
  • Durability - There are fewer moving parts that control brushless motors than PMDC, making them more resistant to wear and impact. They're not prone to burnout due to sparking that brushed motors often encounter, making their lifespan significantly better.
  • Low noise - BLDC motors operate more quietly because they don't have brushes that constantly make contact with other components.
  • Higher efficiency and power density than induction motors (approx. 35% volume and weight reduction with the same output)
  • Long service life and quiet running thanks to precision ball bearings
  • Wide speed range with full motor output due to linear torque curve
  • Reduced electrical interference emission
  • Mechanically exchangeable with stepper motors, hence less construction expense and greater parts variety

DongHui Brushless DC Motors Overview

DongHui offers a comprehensive selection of high performance brushless motors and servomotors used in a wide variety of applications, including medical, office automation, packaging, industrial, aerospace and defense.
