hub gear motor

  • With the cover lid unscrewed we can push out the source of rotary motion and discover a small circular board behind the rear cover of the motor.

  • Besides distributing power it also has three sensors (every fourth coil) for measuring the speed.

  • 12 coils on the outer ring make the 10 magnets on the center spindle go round and round–260 times per minute. The motor has a continuous output power of 180W and 7.3 Nm of torque.

  • The three gears on the flip side are made of plastic to keep abrasion to a minimum.

轮轴齿轮电机

拧下盖子后，我们可以推出旋转运动的源头，并发现电机后盖后面的一个小圆形板。

除了分配功率，它还具有用于（每四个线圈）测量速度的三个传感器。

外圈上12个线圈使中心主轴上的10个磁铁260次/分钟的转动。电机的连续输出功率为180 W，扭矩为7.3 N*m。

翻转侧的三个齿轮由塑料制成，以将磨损保持在最小。
