Introduction of the DC brushless motor

Summarize of the DC brushless motor

This product adopts the new generation frame design of no slots which boasts the advantages of good timing ability, high reliability, no maintenance, no exchanging direction sparkle and so on. Furthermore, it dispels the domino effects of alveolus and it has little vibration of torque, clam operation, low noise, small armature inductance and orientation interfere moment etc. Here are the advantages:

1.The shell of the motor adopts high technology aviation aluminium material; light weight, good ability of giving out heat at the same mechanism intensity.

2.Adopting frame design, no alveolus effects, high efficiency, little volume.

3.The permanent magnet adopts high capability neodymium iron boron, so it minishes the volume and weight greatly at the same output power.

4.The stator adopts import silicon steel, good pulling on magnetism, high efficiency, so it lasts the aviation time.

5.It adopts import high speed bearing at forward and backward respectively; low noise; long life time.

      NOTE: Use only when the special controller (electronic throttle) suits to the brushless motor.

Introduction of installing the DC motor electric for use in model

     The circuit connecting of brushless motor: three lines of (u.. v. w ) can connect with the controller freely, not suit to the color necessary. The motor will reverse by changing two of the three lines (u. v. w ).
