Currently widely used in the field of mechanical manufacturing mobile jig, mainly hydraulic or pneumatic transmission jig. These two types of fixture energy route, the intermediate links, the more energy loss is bigger. In addition, the hydraulic transmission also the environmental pollution caused by oil volatilization and leaking. Below small make up and share brushless dc gear motor controller drives the green fixture systems analysis of knowledge. (1)For brushless dc gear motor controller technique and fixture of self-locking mechanism has carried on the system analysis, for its application in different fixture in the choice to provide necessary information; (2)Series combination proposed self-locking strengthening institutions and deceleration motor controller are combined, resolved stepper motor controller output force is insufficient and not sports d force to maintain sustained technical problems, cracked the key problems of the application of gear motor controller in the fixture; (3)Of reinforcing mechanism and series combination force self-locking mechanism systematically research and innovation design, and presents a mechanical calculation formula of different institutions, in order to provide the reference for the researchers in the field of engineering technology; (4)Design a variety of gear motor controller as the driver of self-locking mechanism of based on clamping device, explains their working principle and technical characteristics, so the technology popularization and application in the field of machinery manufacturing. Study of driven gear motor controller clamping device, is a kind of clamping technology of greening, has the following advantages: (1)There is no pollution of the environment; (2)Direct use of electricity, energy transfer route short, less energy conversion device, high energy efficiency, and overall cost greatly reduced; (3)Clamping device in the process of machining, gear motor controller to stop working, and no longer consumes energy; (4)Compared with the hydraulic or pneumatic clamping device, compact structure, low manufacture cost. Above is today we are going to introduce you to all of the contents of the brushless dc gear motor controller, if you have any questions, you can call contact us, also can personally to the company, will provide the high quality service for you.
