This utility model discloses a slotless AC motor structure based on a reduced-core design, comprising a housing, a stator module, a partial core module, and a rotor module. The housing includes a main body and a base plate. The stator module is built into the housing and includes an annular non-magnetic frame and coils. The partial core module includes several cores, which are mounted one-to-one on a core mounting bracket, with air gaps between adjacent cores. This slotless AC motor structure aims to solve problems such as significant cogging effect, excessive core weight, and inflexible magnetic circuit in traditional motor structures. The motor eliminates the traditional slotted stator structure, adopting a combination design of slotless coils and a partial magnetic core. While ensuring effective control of the magnetic flux path, it significantly reduces motor weight, manufacturing complexity, and improves dynamic response performance.
