摘要： An AC motor having loop windings is provided, which is able to reduce unbalance of three-phase impedance to enhance the motor efficiency. Three loop windings of the three phases are interlinked with magnetic fluxes Φu, Φv and Φw of the respective phases to provide magnetic paths of the three phases. The magnetic paths of the three phases are connected to the respective stator poles of the three phases to configure the motor. The magnetic path of each of the three phases is formed by processing an electromagnetic steel plate using bending to provide a motor configuration having multiple stator poles. Magnetic fluxes of two or more stator poles of the same phase are collected to a single magnetic path to form a three-dimensional three-phase magnetic path without allowing close contact with a magnetic path of a different phase.

A three-phase alternating voltage is applied to the respective phase windings and the junction point to allow the stator to have an electromagnetic action thereby drivably rotating a rotor.

摘要： A brushless AC motor has a rotor, N stator pole group, and plural loop-configuration stator windings. The rotor has magnetic poles with alternating N poles and S poles circumferentially disposed at equal interval. The stator has plural stator poles divided to N stator pole groups. Each group is formed circumferentially on the stator with each of adjacent pairs of the groups mutually differing in circumferential position by a desired amount. The stator windings are formed circumferentially on the stator, with each winding disposed immediately adjacent to a corresponding one of the stator pole groups, with respect to a rotor axis direction. As an example, the stator pole has an approximate parallelogram shape in which a top side and a base side of the stator pole in axis direction of the stator has an approximately same width in rotational direction, and the positions of the top side and the base side is shifted in rotational direction to each other.
