Abstract

The invention discloses a small-size rotary transformer for optimizing tooth socket fit and a winding. The small-size rotary transformer for optimizing the tooth socket fit and the winding mainly comprises a stator and a rotor. The stator is composed of 13 slot cores which are distributed uniformly and sinusoidally distributed two-phase orthogonal stator windings; the rotor is composed of rotor cores which are distributed uniformly and equal-pitch and equal-turns windings. The small-size rotary transformer with optimized tooth socket fit and winding has advantages that the fundamental wave winding coefficient is high while the harmonic winding coefficient is low, the winding is reasonable in form and is convenient to wind, the rotor winding with the power of N to 2 (1, 2, 4, 8) pole pairs is formed easily, the rotor winding with 3, 5 or 7 pole pairs is convenient to form, the pitch of the rotor winding is maintained, the number of turns of each group of elements is maintained, and the miniaturization, universalization and serialization are realized conveniently.

Description

technical field [0001] The invention relates to the technical field of angular position sensors based on the principle of electromagnetic induction, in particular to a small-sized rotary transformer with optimized cog fit and winding. Background technique [0002] In principle, the resolver can be classified as a motor, which belongs to the principle of electromagnetic induction. However, the resolver is not connected with power and torque like a motor, but as a sensing component, it outputs electrical signals (accurate two-phase quadrature positive and cosine voltage signals related to the rotation angle) to sense, or measure angle. Therefore the accuracy of the signal is very important. In order to improve the accuracy, it is usually achieved through the following aspects: ①Precise machining; ②Selecting a reasonable number of slots for the stator and rotor; The winding coefficient of the wave; ④ Increase the size and increase the number of slots, in order to improve the...
