Description

technical field

[0001] This invention relates to rotors and, more particularly, to the assembly of rotor rods and end rings for induction motors.

[0002] In addition, the present invention relates to an induction motor to which such a rotor rod and end ring assembly structure is applied.

[0003] In addition, the present invention relates to a method of manufacturing such a rotor rod and end ring assembly. Background technique

[0004] The rotor of the induction motor is composed of electrical steel plates, rotor rods and end rings. Generally speaking, a copper rotor rod is used. In this case, the copper rotor rod matching the shape of the electrical steel plate is made and inserted into the electrical steel plate, and the upper / lower copper rotor rod and the end ring are connected by welding.

[0005] It is easiest to make the end ring shape into a ring shape to connect with the copper rotor rod, which is shown in figure 1 , refer to figure 1 It is composed of a stator...
