● The blue color iIndicates the same direction of operation as the motor, while the others are in the opposlte direction.

The speed is calculated by dividing the rated speed of the motor by the reduction ratio,and the actual speed wll be reduced by about 2%-20% wilth the change of load size.

Dimension:

57mm bldc motor with 2GN normal gear size drawing

Feature:

  • Wide power range from 5W to 20KW
  • Wide speed range

Speed from 1r/min to 1000r/min match with gearbox; 1000r/min to 10000r/min without gearbox.

  • Wide torque range

Brushless DC motor works with gearbox (normal gearbox, planetary gearbox, worm gearbox) allows for a versatile and efficient power transmission system, catering to a wide range of applications with varying torque and speed requirements.

  • High efficiency and energy-saving

The rotor of the brushless motor is used for the permanent, which can reduce the second loss of the rotor.

  • Good control effect

BLDC motor works with matching controller may achieve simple to complex control, turn from CW to CCW, and meet various communication requirements. BLDC driver can be controlled through 0-5VDC analog signal to adjust the speed.

  • Long service life

With fewer mechanical parts prone to wear and tear, brushless motors generally have a longer operational lifespan.

  • Compact and Lightweight

BLDC motors use of permanent magnet brushless motor rotor. It can achieve higher power density, providing more power in a smaller size.

  • Low noise and smooth operation

Brushless DC motor has no brushes, no sparks will be generated during operation, which greatly reduces friction.
