Abstract

The present invention relates to an electromotive part of an elevator drive, comprising a rotor (24) and a stator (10, 22), wherein windings of the stator and/or the rotor (24) are provided as single tooth windings. An electromotive part of an elevator drive, is provided as an internal rotor motor, and includes a rotor and a stator. Windings of the stator and/or the rotor are provided as single tooth windings, the windings are, at least in part, encapsulated, and the windings are provided as two-layer windings. A method for winding-up windings of an electromotive part of an elevator drive with two-layer windings, includes inserting the windings of individual phases as alternating upper and lower layers.
