Abstract
The invention provides a method for producing machine winding magnetic teeth. A magnetic-inductive component is made of soft magnetic composite material which consists of straight iron powder, an insulating compound and a lubricant. The insulating compound is high-temperature magnetic epoxy powder; the lubricant is zinc stearate. The weight percentage of each component is that the straight iron powder is 90 percent, the high-temperature magnetic epoxy powder is 7 percent and the zinc stearate is 3 percent; the straight iron power, the high-temperature magnetic epoxy powder and the zinc stearate are mixed according to the weight percentage; the mix obtained is pressed to have a needed magnetic tooth shape one time and is sintered for two or three hours in a heating furnace between 1200 DEG C and 1300 DEG C, and the magnetic-inductive component is produced after being cooled. The soft magnetic composite materials are pressed into winding magnetic teeth one time and are assembled. The invention has the advantages that the filling coefficient of the machine winding is high, the resistance of copper wires is decreased, the machine thermoresistance is decreased, the machine torque is increased and the cost is low.
Description
Technical field
