Description
Technical Field
The invention belongs to the field of hollow cup coil processing, and particularly relates to a manufacturing method of a spliced hollow cup coil.
Background
A miniature motor is a type of motor that is small in volume and capacity, with an output power typically below several hundred watts. It mainly consists of stator, rotor and other accessories. The stator is typically composed of a core and windings. The existing miniature motor has the problems that the occupied space of the iron core is large, the winding on the iron core is difficult, and the size is difficult to achieve small. Based on this, there is a coreless motor based on coreless coils in the market, and the windings of such motors are coreless coils, without the need for an iron core, enabling a reduction in the size of the motor.
Existing methods of winding hollow cup coils generally include single layer winding and multi-layer winding.
The single-layer winding method is to wind the turns of the air-core coil on the outer surface of the insulating pipeline in a single-layer mode, and the single-layer winding method is divided into indirect winding and tight winding, wherein the indirect winding is generally used in some high-frequency resonance circuits, and the winding method in the mode can reduce the capacitance of the high-frequency resonance line diagram and stabilize some characteristics. The tight winding is based on coils with a relatively small range of resonant coils.
The multilayer winding method is to wind a coil in a multilayer manner, and the inductance of the coil is relatively large. The multi-layer winding method comprises two types of closely wound winding and honeycomb winding, the closely wound winding is arranged in a relatively tight manner, a layer-by-layer distribution is needed, the capacitance generated by the winding coil is relatively large, the honeycomb winding is arranged at a certain angle, the arrangement is not very flat, but compared with the closely wound method, the capacitance is relatively small. Some high-voltage resonance circuits need to meet the current value and the voltage resistance between coils when winding the air-core coils, and consider the heat condition of the coils when winding the air-core coils.
The coil is formed by one-time winding in a single-layer winding method or a multi-layer winding method, the winding difficulty is high, the middle cannot be interrupted, and the requirement on the continuity of the production process is high.
