Printed alternating-current motor

Abstract

The invention discloses a printed alternating-current motor, and is suitable for being used in the field of industrial micro-type equipment. The printed alternating-current motor comprises a stator iron core, insulating paper, a stator printed board, a rotor, a bearing, a rotating shaft and the like, wherein the rotor can be a permanent magnet synchronous machine rotor and can also be an asynchronous machine rotor. The permanent magnet synchronous machine rotor is arranged by attaching a permanent magnet onto a rotor iron core, and the asynchronous machine rotor is arranged by fixing the stator printed board onto the rotor iron core. The stator printed board and a rotor printed board are printed circuit boards respectively, wherein the multi-layer stator printed board adopts a wavy winding, the rotor printed board adopts a cage winding, and the rotor iron core and the stator iron core are formed by laminating silicon steel sheets respectively. Due to the fact that the printed alternating-current motor stator adopts the printed board, the volume of the motor is greatly reduced, so that the motor is lighter and thinner, the trouble of ordinary motor winding is reduced, and the printed alternating-current motor is convenient for large-scale production. Moreover, a Hall sensor is integrated on the stator printed board of the printed alternating-current motor, so that the printed alternating-current motor is convenient to use together with a controller.

AI Technical Summary

Benefits of technology

This patented technology allows for smaller motors with fewer parts while still maintaining their high efficiency compared to traditional designs that use multiple coils or windings. It also improves on conventional methods by allowing more circuits within one part instead of requiring separate connections between different components. Additionally, it includes an improved method called Multiplexed Structure (MCS) where multiple printed circuitboards connect together at once through interconnections made up of noncrossable metal foil strips. Overall, this new design makes manufacturing these types of machines faster and easier than previous techniques.

Problems solved by technology

This technical problem addressed by this patented describes how current methods used for creating high-density printing circuits involve complex processes involving multiple steps such as wire bond connections or insulation between different parts of an inductive device's core material. Additionally, there may also exist limitations on available space due to lack of sensory feedback from the printed circuitry itself that can help estimate its location within the machine housing without adding extra components like switches.
