Embodiment 1

[0016] A new type of rotor, such as Figure 1-3 As shown, it includes an end cover 1, an end ring 3, a guide bar 4 and a rotor core 5. The rotor core 5 is provided with an end ring 3 and a guide bar 4. The end ring 3 and the guide bar 4 are integrally formed. The end cover 1 is connected with the end ring 3, the end cover 1 is a steel end cover 1, the end ring 3 is a pure aluminum end ring 3, the guide bar 4 is a pure aluminum guide bar 4; the end cover 1 is provided with a shaft sleeve 6. There is a rotating shaft inside the sleeve 6, and the rotating shaft drives the rotor to rotate through the sleeve 6 on the end cover 1. Since the end cover 1 is made of steel, the end cover 1 can withstand the rotation of the rotor. Since the end ring 3 and the guide bar 4 are pure Made of aluminum, pure aluminum has the effect of improving motor efficiency and reducing motor loss compared with traditional silicon aluminum.

Embodiment 2

[0020] Same as embodiment 1, the difference is that the end cover 1 is made of silicon aluminum. Since the end cover 1 is made of silicon aluminum, the end cover 1 can withstand the rotation of the rotor, and the number of riveting columns 2 is 6. The number of riveting holes 7 is 6, the inner diameter of the end ring 3 is 60 mm, and the outer diameter of the end ring 3 is 75 mm.

Embodiment 3

[0022] Same as embodiment 1, the difference is that the number of riveting posts 2 is 12, the number of riveting holes 7 is 12, the inner diameter of the end ring 3 is 150 mm, and the outer diameter of the end ring 3 is 210 mm.

Abstract

The invention relates to the field of motor, and discloses a novel rotor which includes an end cover (1), an end ring (3), a conducting bar (4) and a rotor iron core (5). The rotor iron core (5) is provided with the end ring (3) and the conducting bar (4) thereon. The end ring (3) and the conducting bar (4) are formed integrally. The end cover (1) is connected with the end ring (3). The end cover (1) is a steel end cover (1) or a silicon-aluminum end cover (1). The end ring (3) is a pure aluminum end ring (3). The conducting bar (4) is a pure aluminum conducting bar (4). The end cover (1) is provided with a shaft sleeve (6) thereon. The rotor of the invention has the advantages of being capable of stably maintaining the rotation of the rotor, improving the motor efficiency and avoiding the deformation of the rotor.

Description

technical field [0001] The invention relates to the field of motors, in particular to a novel rotor. Background technique [0002] The external rotor motor is composed of a stator and a rotor. For a general external rotor motor, the conductor part of the rotor (guide bar and end ring) and the end cover are generally made of silicon-aluminum materials. In recent years, as the requirements for motor efficiency have become higher and higher, Because pure aluminum can improve the efficiency of motors, many manufacturers have begun to use pure aluminum to manufacture rotors. However, due to the soft material and insufficient strength of pure aluminum, the end cover as a support in the rotor cannot withstand the rotation of the rotor. After long-term use, it cooperates with the shaft. The pure aluminum part is prone to deformation, which will lead to unexpected situations such as unstable rotor rotation and uneven air gap. Manufacturers also use silicon-aluminum instead of pure a...
