Single phase electric motor for vehicle`s electromagnetic actuator, has one half-shell with teeth having rectangular shape different from trapezoidal shape teeth of another half-shell, and having width equal to that of rotor poles

摘要

The motor has a rotor (4) housed inside a stator in a free space delimited by a housing formed by teeth (10, 11), and a magnetic circuit with two half-shells (8, 9). The rotor turns outside the stator, opposite to an outer wall formed by the teeth. Each half-shell (8 or 9) has the teeth (10, 11) extending towards the other half-shell, respectively along a direction parallel to a shaft (5) of the rotor. The teeth (10) of the half-shell (8) have a rectangular shape different from the teeth (11) having trapezoidal shape, and have an angular width equal to that of magnetic poles of the rotor.
