Problems solved by technology

In addition, in order to reduce the reluctance of the magnetic circuit in the traditional motor, silicon steel sheets with high magnetic permeability are laminated to make the iron core, and the existence of the iron core leads to problems such as large volume, heavy weight, large loss, and large vibration noise of the motor.

Embodiment Construction

[0015] Such as figure 1 As shown, the AC disc coreless permanent magnet synchronous motor based on the Halbach array of the present invention includes an outer rotor 1, a stator armature 2, a magnetic steel disc 3, a bracket 4, a rotating shaft 5, and a stator lead 6. The motor is a double outer rotor Structure, the outer rotor 1 and the rotating shaft 5 are connected by bearings, the magnetic steel disc 3 is glued to the inner wall of the rotor 1, and the magnetic steel disc 3 adopts figure 2 The Halbach-type permanent magnet array structure shown generates an axial magnetic field. The stator armature 2 adopts a coreless structure and is directly formed by injection molding of windings. The stator armature 2 is fixed on the shaft 5 through a bracket 4; the double outer rotor 1 and the stator The armature 2 forms a double-sided air gap. The stator lead 6 passes through the center of the rotating shaft 5.

Abstract

An iron core free permanent magnetic and synchronous motor of AC disc type based on Halbach array is prepared as applying double external rotator structure, binding magnetic steel disc at inner wall of external rotator, applying Halbach permanent magnet array structure for magnetic steel disc to generate axial magnetic field, utilizing iron core free structure for stator armature being formed by winding injection directly, using double rotators and stator armature to form air gap at two sides. The prepared motor is suitable to be used at occasion of applying large torque and direct driving.

Description

Technical field [0001] The invention relates to the technical field of motors, in particular to an AC disc coreless permanent magnet synchronous motor based on a Halbach array. Background technique [0002] As a modern high-performance servo motor and a high-torque direct drive motor, the disk-type permanent magnet synchronous motor has developed rapidly at home and abroad in recent years. With the rise of high-tech products such as CNC machine tools, industrial robots, computers, and the demand for some special application systems, higher performance indicators and thin installation requirements are put forward for servo drive motors, and disk permanent magnet synchronous motors are gradually replacing Traditional servo motor products. High power, high functionality and miniaturization are the current development directions of permanent magnet motors, and high energy density and high efficiency are the common requirements for the design of various permanent magnet motors. Consid...
