Servo motors usually wrap a three-pole rotor with a thin copper wire. When current flows through the coil, a magnetic field is generated, which repels the magnets around the rotor and generates a rotating force. According to the laws of physics, the moment of inertia of an object is proportional to its mass, so the greater the mass, the greater the force required to turn it. In order to find the servo with high speed and low energy consumption, the thin copper wire is then wound into a very thin hollow cylinder,

伺服电机通常用一根细铜线缠绕三极转子。当电流流过线圈时，会产生磁场，磁场会排斥转子外围的磁体，产生旋转力。根据物理定律，一个物体的惯性矩与它的质量成正比，所以质量越大，转动它所需要的力就越大。为了找到舵机的速度快,能耗小,然后将细铜线缠绕成一个非常薄的空心圆柱体，

The servomotor is usually wound with a thin copper wire around the three pole rotor. When the current flows through the coil, there will be a magnetic field, which will repel the magnets around the rotor and generate a rotating force. According to the laws of physics, the moment of inertia of an object is directly proportional to its mass, so the larger the mass, the greater the force required to rotate it. In order to find the steering gear with high speed and low energy consumption, the thin copper wire is wound into a very thin hollow cylinder,
