The performance of the brushless dc motor controller is able to fully play out, the key is it to pray for the heat treatment of a role, heat treatment equipment is actually metal material is placed within the certain medium heat, heat preservation, cooling, by changing the material surface or internal crystal phase structure, to change a thermal processing equipment performance, the specific the equipment using heat treatment? The following knowledge will be detailed introduction. 1, remove stress annealing treatment: the purpose is to eliminate the casting force, improve the mechanical performance and machining performance. 2, graphitizing annealing: if the brushless dc motor controller the section size of the difference is bigger, in thin cross section of easy to form the white, it must be for graphitizing annealing, the purpose is to eliminate chilling. 3, other materials: there are aluminum alloy of brushless dc motor controller, of as cast iron, heat treatment goal is similar, but important in order to improve the mechanical properties of aluminium alloy parts need to be solid solution treatment time. 4, homogenizing annealing: the more important of the brushless dc motor controller or other cast iron materials of brushless dc motor controller, in order to improve the mechanical properties, the need for homogenizing annealing, formed in the casting process because of the many chemical composition segregation, its purpose is to uniform organization, ensure each section mechanical performance, improve the mechanical properties. We in the casting of the brushless dc motor controller, master the knowledge is more important, in this way, can let a equipment to better play its role performance, but also will further reduce the equipment failure, why not?
