Electric machine and method for manufacturing it

摘要

A method for making a rotary electric machine comprises the steps of: preparing a core (18) having a plurality of pole expansions and a plurality of windings (100, 200, 300) made of electrically conductive material on the pole expansions, where at least a part of the windings (100, 200, 300) is made from a conductor wire having a free end (14) that can be connected electrically to a mains power supply; stably coupling to each other at least two free ends (14) of different windings (100, 200, 300) so as to connect them to a single power supply terminal; twisting the coupled ends (14) together to form a single electrical termination (5, 6, 7) twisted along a principal line of extension of the electrical termination (5, 6, 7).

主权项

1. A stator for an electric machine, the stator comprising:
a core having a plurality of pole expansions and a plurality of windings made of electrically conductive material on the pole expansions, where at least a part of the windings is made from a conductor wire having a pair of free ends that can be connected electrically to a mains power supply; and two or more electric terminations electrically connectable to respective electrical power supply terminals; characterized in that at least one of the electric terminations is formed by two free ends of respective different conductor wires and has a twisted form created by twisting the ends along a principal line of extension of the ends, an eye being formed, for each electric termination, by the respective conductor wires at the base of the twisted part, the electric terminations also comprising a flexible portion which is movable towards the core and away from the core.
