A rotor for a rotating electric machine includes a rotor winding arranged for conjoint rotation on a rotor shaft, and a slip ring body arranged on an axial end of the rotor shaft and having an end face on an axial end of the slip ring body opposite to the rotor winding. The slip ring body includes connection adapters which project axially beyond the end face of the slip ring body for connection of line ends of the rotor winding. A driver unit for a rotary encoder is fastened to the end face of the slip ring body and/or to the axial end of the rotor shaft and electrically insulated from the connection adapters. A centrifugal force support ring is arranged on the end face of the slip ring body such that the connection adapters and the driver unit are arranged in a through-opening of the centrifugal force support ring.

The present invention is a structure of an electrical connection portion formed by thermal bonding of a terminal 53 of a current-carrying component 50 of a motor and a winding wire 30. The terminal 53 includes a lock portion 53a positioned on a base end side and a fusion portion 53b positioned on a distal end side. The winding wire 30 includes a binding portion 31 wound around the lock portion 53a and has a one end portion 36 coupled to a molten ball 55 generated at the fusion portion 53b; and a coupling wire portion 33 tightly stretched from a main winding wire portion 34 of the motor disposed in a wound state and continuous to the other end portion of the binding portion 31. The one end portion 36 of the binding portion 31 is in a state where tension pulling the coupling wire portion 33 to the main winding wire portion 34 side does not act.

The present invention provides an electric machine with a stator (1) and a rotor (21) mounted movable relative to the stator, wherein the stator comprises a plurality of slots (2) for receiving a stator winding. Exactly one conductor portion (3) of the stator winding is inserted into each slot. The conductor portions (3) are short-circuited with one another in a short-circuiting element on a first side (5) of the stator and are integrally formed with said short-circuiting element. On a second side (6) of the stator, the conductor portions (3) are connected to in each case one terminal of a power supply unit (8) which supplies adequate phase currents.
