IMPROVING OF STEPPER MOTOR BEHAVIOUR USED ON CINEMATIC CHAIN OF MACHINE-TOOLS FOR ELECTRICAL DISCHARGE MACHINING
2013 Romanian Association of Nonconventional Technologies Romania
In this paper is presented the design of a power interface for stepper motor control, used in electrode tool displacement system for Electrical Discharge Machining and Industrial Robots. Using the current limiting technique, for high torque bipolar stepper motor, a reduction of the current rise time and the fall time was obtained. In this case, for full step mode, the maximum speed of stepper motor was increased significantly. The project was developed around a 16 bit modern microcontroller.fatcat:5z3fovmnlzafrl44rh6zhf37gu
