Brushless DC Motor

What is brushless dc motor?

A brushless direct current motor (BLDC) is a small but powerful type of electric motor that uses direct current as its power source. Because of their size and efficiency, BLDCs are increasing in their popularity and the number of applications they're used for.

 

BesFoc offers a wide range of brushless DC motor products featuring:

  • Output Power from 15 W (1/50 HP) up to 3000 W (4 HP)
  • Motor size from 28mm to 110mm ( Nema 11 to Nema 42)
  • Integrated brushless servo motor (pulse / RS485 / CANopen) options
  • Many different shaft kinds available
    • Spur gearbox, worm gearbox, planetary gearbox available
  • Electromagnetic Brake / Encoder options
  • AC or DC Input Drivers

BesFoc Brushless DC Motors has the following main advantages:

(1) With good mechanical characteristics and regulating characteristics, can replace the DC brush motor speed regulation, frequency conversion motor speed regulation, induction motor plus reducer speed regulation. 
(2) Can run at low speed and high power, save the reducer, and directly drive the large load. 
(3) It has many advantages of the traditional DC brush motor, but also eliminates the brush and collector ring structure. 
(4) Excellent torque performance, medium, and low-speed torque performance start torque is large, start current is small. 
(5) Step-less speed regulation, wide speed range, strong overload capacity. 
(6) Small volume, light weight, large output. 
(7) Soft start, soft stop, and good braking characteristics can leave out the original mechanical or electromagnetic device. 
(8) The motor itself has no excitation loss and brush loss, high efficiency, and a good comprehensive power-saving effect. 
(9) High reliability, good stability, strong adaptability, and simple repair and maintenance. 
(10) Vibration resistance, low noise, small vibration, smooth operation, and long life. 
(11) No spark, especially suitable for public places, anti-interference, good safety performance.

 

Brushless dc motor application:

Medical equipment, logistics transportation, industrial automation, textile machinery, laser, drawing, traditional Chinese medicine ingredient industry, etc
BesFoc has officially launched its new three-phase BLDC products, which are designed to benefit customers with optimized designs for noise reduction, vibration reduction, and longer working life. BLDC motors can be widely used in FA, pumps, valves, solar energy, automotive, and other fields.
