Abstract
As China's science and technology and rapid economic development and accession to WTO which makes the internationalization of China's economy, China's Zhejiang Province, in particular, has quickly become the world's major production base. However, due to production efficiency, product quality, energy consumption and environmental pollution constraints, in China the increase in total production is not entirely brought about by the simultaneous increase in economic benefits, including the quality of the product can not be ignored but also a factor. Especially in the Zhejiang Province in China, in order to make the quality of mechanical products relatively large improvements in production and maintenance of all types of machinery and the widespread use of corporate induction bearing heater, and reality becomes all the more pressing.
In this paper, bearing heaters designed to convenience, stability, security as a design concept, will be a complex circuit design over the past simplistic, easy processing and maintenance, while the use of modern materials as the core of the new, as well as to meet the conditions of "cold generation of heat, "the orientation of the development, design. For heating small bearings more convenient and safe.
Keywords： Bearing heater, transformer design, the electromagnetic parameters, the soft magnetic materials
