Abstract
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.
