Abstract
The invention relates to a procedure for preparing the windings for an electric motor. The magnetic core (20) of the stator and/or rotor of the motor is provided with slots (24,25) in which winding coils (2; 5,7;15,17) can be fitted. According to the invention, the winding coils (2) are wound from winding wire and shaped substantially into their final form, the cross-section of the coil sides (15,17) corresponding to the space reserved in the slot (24,25) for the coil. The winding coils (15,17) are fitted in place in the slots (24,25) provided in the magnetic core.
Claims13
A method for preparing the windings for an electric motor, the magnetic core of the stator and/or rotor of said electric motor being provided with slots in which winding coils can be fitted, said method comprising the steps of:
- winding the winding coils from winding wire by a random winding method;
- shaping the winding coils substantially into their final form by winding the winding coils around trough shaped formers;
- and
- fitting the winding coils in place in the slots provided in the magnetic core, after the step of shaping is completed.
