The invention relates to a brushless, electronically commuted motor, more particularly one used as drive motor for a ventilator drive mechanism in an automobile, comprising a permanent magnetic outer rotor ( ), in which a stator ( ) with three winding wires staggered at 120&deg; el is mounted, in addition to several winding coils for each winding wire. The pitch of the coil of the winding coils ( ) is s smaller than the pitch of the pole and 0.5 coils are wound per pole and wire ( ). A flat, compact, light-weight, silent and efficient EC motor ( ) is obtained due to the fact that each winding wire consists of several parallel-connected windings, the outer rotor ( ) has at least p&equals;3 pole pairs and a control plate with conductor rails is provided to connect the individual winding coils.
