A dual-channel servo motor

Abstract

The present invention provides a dual-channel servo motor belonging to the technical field of special motors and comprising stator cores, field windings, rotor cores, stator isolation blocks, bearings and shafts. The stator cores are fixed on the shafts, and the rotor cores can rotate around the shafts under the action of the bearings. The rotor cores are provided with 16 uniformly distributed convex rotor poles; and there are nine fan-shaped stator cores, and each of the stator cores is provided with two convex stator poles. The outer side of the stator fixing block between every two stator cores is provided with an armature slot; and an excitation slot is arranged at the outer side between the two stator poles of the same stator core, and the field windings and armature windings are embedded in the excitation slot at the outer side; the inner side of each stator core is provided with an inner-side excitation slot and the inner-side excitation slots are embedded with the excitation windings; each stator pole is wound with concentrated-type armature windings, and the adjacent armature windings are wound oppositely. The stator cores of the present invention are independent from each other, and the excitation windings on each stator core are energized to generate a magnetic field, and the magnetic circuits are isolated from each other, thereby improving the efficiency and the reliability of the motor.

Description

technical field [0001] The invention relates to a dual-channel servo motor, which belongs to the technical field of special motors. Background technique [0002] Whether in daily life or in industrial production, you will see servo motors. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an actuator to convert the received electrical signal into an angular displacement or angular velocity output on the motor shaft. Among them, the electric excitation servo motor is a kind of servo motor. The difference between it and the permanent magnet servo motor is that the electric excitation servo motor generates magnetic flux by energizing the excitation winding instead of using permanent magnets to provide magnetic flux, thus solving the problem of permanent magnet The problem that the magnetic field of the servo motor cannot be adjusted. [0003] At present, there are not many invention pat...
