Abstract

This invention discloses a direct-drive low speed magnetic synchronous wind generator with a sectional module stator structure including a stator core set in sections, in which, the internal circle of the core is divided into k1 fan zone sets uniformly and three phases of A, B and C in each set are in three fan zones in same area, each zone belongs to one phase, K2 teeth are set on the stator core of a zone uniformly, a groove is opened between adjacent two teeth, the teeth distance of which is a pole distance, a holddown is set between the two adjacent stator cores and a full-pitched centralized coil is winded on each tooth of the stator cores, the winding coefficient of the motor is 1, the end of the stator winding is short and easy to be winded mechanically and continuously, the core sections are independent to each other on the base and easy to be exchanged.

Description

technical field [0001] The invention belongs to the technical field of electrical engineering, and relates to a segmented modular stator structure, in particular to a direct-drive low-speed permanent magnet synchronous wind power generator. Background technique [0002] With the development of human economy and society, the demand for energy is increasing, and energy is the basic material guarantee for human production and life. With the increasing shortage of conventional fossil energy and the improvement of public awareness of environmental protection, human beings pay more and more attention to the development and utilization of renewable energy. As an important item in the new energy strategic planning, wind power has been widely and fruitfully developed all over the world. Generator, as an important part of wind power system to convert wind energy into electric energy, is a research hotspot in wind power technology. In the last 20 years, wind power generators have con...
