Abstract

The invention relates to an integer-slot bilayer ring-winding linear electric motor, belonging to the technical field of motors, and solving a problem that an insulation technique of each phase winding is complex and the manufacturing cost is increased as the end part of each phase winding exposed out of an iron-core teeth is longer in a traditional bilateral flat three-phase linear permanent magnetic synchronous motor. The integer-slot bilayer ring-winding linear electric motor mainly consists of a primary unit, a secondary unit and air gaps, wherein the primary unit mainly consists of a primary iron core and a primary winding, the primary iron core is in a shape of a flat, a left air gap side plane and a right air gap side plane of the primary iron core are symmetrically provided with coil slots of 2km vertical to the motion direction, m is a phase number of a motor, k is a positive integer, q is the number of each electrode and each phase of the motor, a coil forming a winding is rectangular, two effectively sides of each coil are embedded in left and right symmetrical slots of the primary iron core, two coil sides are embedded in each slot, coil slots of two sides of the primary iron core are mutually related, the secondary unit is of a bilateral structure and is provided with the air gaps with the primary unit. The invention is suitable for annular winding linear motors.

Description

technical field [0001] The invention relates to an integer-slot double-layer circular winding linear motor, which belongs to the technical field of motors. Background technique [0002] The armature core tooth pitch τ of the traditional two-sided flat three-phase linear permanent magnet synchronous motor t The pole distance τ from the permanent magnet p Satisfy the relation 3τ t =τ p , a coil side is embedded in each slot, and the coil pitch is equal to the pole pitch. This winding structure is called an integer slot single-layer winding. The winding of the motor is as Figure 10 As shown, the coil of the A-phase winding is wound in the first slot and the fourth slot, while crossing the second and third slots, and the coil of the C-phase winding is wound in the second and fifth slots. Wraps inside the slot, while crossing the third and fourth slots, and so on. The main problem of this type of winding is that the ends of the winding coils of each phase exposed outside th...
