Communication servo motor

The structure of the stator of an AC servo motor is basically similar to that of a capacitor phase separated single-phase asynchronous motor The stator is equipped with two windings located 90 ° apart from each other, one of which is the excitation winding Rf, which is always connected to the AC voltage Uf; The other is to control winding L and connect the control signal voltage Uc. Therefore, AC servo motors are also known as two servo motors.

The rotor of an AC servo motor is usually designed as a squirrel cage, but in order to provide the servo motor with a wide speed range, linear mechanical characteristics, no "self rotation" phenomenon, and fast response performance, it should have two characteristics compared to ordinary motors: high rotor resistance and low moment of inertia. There are currently two types of rotor structures that are widely used: one is a squirrel cage rotor made of high resistivity conductive materials with high resistivity bars. In order to reduce the rotational inertia of the rotor, the rotor is made slender; Another type is a hollow cup-shaped rotor made of aluminum alloy, with a very thin cup wall of only 0.2-0.3mm. In order to reduce the magnetic resistance of the magnetic circuit, a fixed internal stator needs to be placed inside the hollow cup-shaped rotor Hollow cup-shaped rotors have a small moment of inertia, rapid response, and smooth operation, making them widely used.

When there is no control voltage, only the pulsating magnetic field generated by the excitation winding is present in the stator of the AC servo motor, and the rotor remains stationary. When there is a control voltage, a rotating magnetic field is generated inside the stator, and the rotor rotates in the direction of the rotating magnetic field. Under constant load, the speed of the motor varies with the magnitude of the control voltage. When the phase of the control voltage is opposite, the servo motor will reverse.

Permanent magnet AC servo motor

Since the 1980s, with the development of integrated circuits, power electronics technology, and AC variable speed drive technology, permanent magnet AC servo drive technology has made outstanding progress. Famous electrical manufacturers in various countries have successively launched their own AC servo motor and servo drive series products and continuously updated them. The communication servo system has become the main development direction of contemporary high-performance servo systems, which poses a crisis of phasing out the original DC servo. After the 1990s, the commercialized AC servo systems in various countries around the world were driven by sine wave motors with fully digital control. The development of communication servo drive devices in the field of transmission is advancing rapidly.

The main advantages of permanent magnet AC servo motors compared to DC servo motors are:

⑴ Without electric brushes and commutators, it works reliably and requires low maintenance and upkeep.

⑵ The heat dissipation of the stator winding is relatively convenient.

⑶ Small inertia, easy to improve the system's speed.

⑷ Suitable for high-speed and high torque working conditions.

⑸ Under the same power, it has a smaller volume and weight.
