Embodiment Construction

[0013] The invention will be further described below with reference to the accompanying drawings and in combination with specific embodiments, so that those skilled in the art can implement it by referring to the description, and the protection scope of the present invention is not limited to the specific embodiments.

[0014] The invention relates to a two-phase fractional slot air-core compensation pulse generator, which includes a stator and a rotor, and the stator includes two-phase armature windings, such as figure 1 As shown, the two-phase armature windings are A-phase armature winding 1 and B-phase armature winding 2, and there is a 90° electrical angle difference between A-phase armature winding 1 and B-phase armature winding 2. The armature winding 1 is composed of two coils (A1 coil and A2 coil), and the B-phase armature winding 2 is composed of two coils (B1 coil and B2 coil), that is, the two-phase winding has a total of four coils, and these four coils are Concent...

Abstract

A two-phase fractional slot air core compensation pulse generator including stator and rotor, the stator comprises a two-phase armature winding, A 90 DEG electric angle difference exists between thattwo-phase armature winding, the two-phase armature winding consists of two coils, All coils of the two-phase winding are concentric centralized windings, all the coils of the two-phase winding are uniformly distributed in the stator space, the coils of different phases are staggered, and there is no gap between two adjacent coils, A rotor includes an excitation winding, the excitation winding consists of six excitation coils, the above-mentioned pulse generator is a pulse generator with two phases, Four-slot, six-poles, and satisfies the slot pole number combination constraint condition of fractional slot winding with pitch of 1, thus avoiding the cross-overlap problem of the ends of different phase coils of the traditional distributed winding, greatly reducing the manufacturing difficultyof the stator winding of the air-core pulse generator, and the discharge output capability of the motor can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a two-phase fractional slot air-core compensation pulse generator. Background technique [0002] In existing air-core compensation pulse generators, composite materials with a high strength / density ratio are used to replace traditional ferromagnetic materials, thereby increasing the energy density and power density of the motor. Due to the non-magnetic conductivity and poor processability of composite materials, the motor is usually designed as a slotless structure. The stator armature winding is generally processed into a concentric racetrack shape. The overall volume is large, and it is bonded to the inner wall of the stator with epoxy resin. For motors with two-phase armature winding structure, the existing integer-slot distributed winding design structure inevitably has overlapping overlaps at the ends of the two-phase windings. big difficulty.
