Motor guide bar and preparation method thereof

Abstract

The invention discloses a motor conducting bar which comprises the following components in parts by weight: 3-5 parts of zinc, 0.1-0.3 part of chromium, 0.0015-0.00152 part of arsenic, 0.0015-0.00152 part of antimony, 0.0005-0.00051 part of bismuth, 0.0025-0.00253 part of iron, 0.0010-0.00101 part of tin, 0.0020-0.00202 part of nickel, 0.0025-0.00253 part of sulfur, 0.001-0.00101 part of phosphorus and the balance of copper, totaling 100 parts. The invention also discloses a method for preparing the motor conducting bar. The used material is simple and readily available, the preparation method is simple, and the cost is low; and a proper amount of chromium is added into the prepared motor conducting bar, so that the performance of the motor conducting bar is improved.

Description

technical field [0001] The present invention relates to metal materials, in particular to motor bars, and to a method for preparing such motor bars. Background technique [0002] Conventional motor guide bars are made of pure copper and brass. However, they have poor electrical conductivity, easy oxidation, and low tensile strength, which will affect the performance of the motor. With the acceleration of industrialization, energy issues have become the focus of contemporary society, and research on energy-saving materials has become an important aspect of materials research. As one of the important basic components of various types of machinery, the efficiency of the motor has a major impact on energy conservation and even the sustainable development of the economy. More importantly, in new motors such as high-performance self-starting permanent magnet motors and railway high-speed traction motors, there are some new requirements for the performance of the guide bar, such a...
