Description

Technical Field

[0001] The utility model relates to the technical field of motor processing devices, in particular to a stator core PCB installation system. Background Art

[0002] A servo motor is an engine that controls the operation of mechanical components in a servo system. It is an auxiliary motor indirect speed change device. It can convert voltage signals into torque and speed to drive the control object. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. It has the characteristics of small electromechanical time constant, high linearity, and starting voltage. Its working principle can be simply summarized as: input control signal → servo controller → servo motor → output motion. The servo system consists of a servo motor, a servo controller, and a feedback device. When the servo motor receives a pulse signal, it will rotate an angle corresponding to a pulse to achieve displacement.

[0003] The structure of a servo motor is mainly composed of stators, rotors, encoders and other components. The stator of a servo motor is usually made of laminated silicon steel sheets, and two-phase or three-phase windings are embedded in the surface slots. These windings are used to generate a rotating magnetic field. The rotor is the rotating part of the servo motor, and its structure is related to the type of motor. For permanent magnet servo motors, the rotor is usually composed of permanent magnets, which rotate in the magnetic field generated by the stator.
