Problems solved by technology

During the working process, it is often necessary to connect a cooling fan on one side of the rotor end ring, while the conventional cooling fan not only occupies a large space, but also easily wears out with the rotor end ring during the working process, resulting in damage to the fan; in addition, the rotor end ring The fixation with the rotor often depends on driving the aluminum guide bar into the groove on the rotor, which also has certain potential safety hazards

Abstract

The present invention relates to a rotor end ring including a circular ring. The rotor end ring is characterized in that: the circular ring is provided with a plurality of circular through holes, the surface of the circular ring between two adjacent through holes is provided with a rotor fan blade respectively, the rotor fan blade is triangular prism shaped, the interior circumference of the circular ring is provided with a circular platform raised outwards, and the circular ring and the inner surface of the circular platform are provided with recessed rotor clamping grooves evenly. The rotor fan blade of the rotor end ring can achieve a better heat dissipation effect when the rotor turns, the circular ring is convenient to fix the rotor end ring, and the recessed rotor clamping grooves enable the rotor end ring to preferably cooperate with the rotor for working.

Description

technical field [0001] The invention relates to the field of motor manufacturing, in particular to a rotor end ring. Background technique [0002] The cast aluminum rotor of the motor is generally composed of rotor core, guide bar and end ring. The aluminum guide bar is driven into the groove on the rotor, and the rotor core is exposed at both ends. The two ends of the aluminum guide bar are respectively cast and connected with cast aluminum end ring. During the working process, it is often necessary to connect a cooling fan on one side of the rotor end ring, while the conventional cooling fan not only occupies a large space, but also easily wears out with the rotor end ring during the working process, causing damage to the fan; in addition, the rotor end ring The fixation with the rotor often depends on driving the aluminum guide bar into the groove on the rotor, which also has certain potential safety hazards. [0003] Therefore, based on these problems, it is of great p...
