Problems solved by technology

However, the use of fasteners is limited by the potential difference between the composite material and the fastener
In addition, the number of components used increases, which is contrary to a stable and simple design

Embodiment Construction

[0024] From Figure 7 to 9 As can be seen, such as generators and / or motors having a rotor of the motor 2, the rotor 2 rotates in the operation of the motor. The rotor 2 has a plurality of grooves 3, the introduction of electrical conductors (not shown) in these grooves. Two end faces of the electrical conductors present in the outer rotor 2, and an end portion constituting the winding. The rotor 2 has a winding end ring 1, the winding end portion of the outer ring radially contracted at a winding end portion. Winding the end loop 1 has a shape memory material.

[0025] Figure 5 with Figure 7 to 9 Shows the winding ends of the ring 2 contracts in the rotor 2, so that the winding ends of the ring 2 along the protruding direction of the rotor axis 4 of the rotor 2. From Figure 5 As can be seen, the end portion of the winding ring 26 has a step at a radially inner surface, the step 26 abuts against the end surface of the rotor 2. Thus, the axial position of the winding end portion ...

Abstract

The invention relates to a rotor for an electric machine, comprising a winding end and a winding end ring (1), which is shrunk on the winding end radially on the outside and has a shape-memory material.

Description

Technical field [0001] The present invention relates to a method for the rotor of the motor, and a method of assembling a rotor for a method for the removal of rotor. Background technique [0002] An electric motor such as a motor or generator having a stator and a rotor. The stator and rotor each having a winding end portion of the electrical conductor. In particular, the winding end of the rotor tends to vibrate in operation of the motor. Vibration can cause the end winding shorten motor life. A motor having a rotor cover typically, the cover is disposed around the rotor end winding and the winding end portion of the reinforcement, so that the end of the winding operation of the motor are less prone to vibration. [0003] For example, the rotor cover may be made of a metal. To rotor cover mounted on an end portion of the winding, the rotor cover is heated and shrunk by cooling at the end of the winding portion, so that the rotor cover is not detachably secured to the winding en...
