Abstract

In a stator (1) for a three-phase electric motor, in which three coils (U1 - U3, V1 - V3, W1 - W3) of each phase (U, V, W) are arranged distributed over the circumference and are connected in series, with the phases (U, V, W) being delta-connected, the coils (V1 - V3) of one of the phases (V) are connected with the opposite direction of rotation with respect to the coils (U1 - U3, W1 - W3) of the other phases (U, W). Contact points (4 - 6) for simultaneously making contact with two phases (U, V, W) are arranged between mutually adjacent coils (W4, U1; V4, W1; U4, V1). The stator (1) can thus be manufactured particularly inexpensively.
