Abstract
The servo motor includes a casing, a stator, a rotor and a circuit board. The casing has a hollow body, a first bearing and a second bearing. The hollow body is mounted between the first bearing and the second bearing. The stator is disposed inside the hollow body, and surrounds an axial hollow portion. The rotor is disposed inside the stator. A shaft passes through the rotor in an axial direction, and two ends of the shaft are respectively mounted on the first bearing and the second bearing. The circuit board is disposed inside the hollow body and interposed between the stator and the first bearing, the periphery of the circuit board has a plurality of solder pads electrically connected to the stator. An outer surface of the circuit board has a protection layer, which covers the region of the solder pads near the outer edge of the periphery.
