This paper proposes a novel hybrid-type permanent magnet motor (HPMM) that simultaneously applies ferrite-PM (Fe-PM) to reduce the amount of NdFeB (Nd-PM) used in electric vehicle traction motors. Conventional HPMM can be divided into parallel type (P-HPMM) and series (S-HPMM). P-HPMM is advantageous for PM torque improvement because it obtain high flux linkage, but there problem Fe-PM demagnet...

IBM PCs with parallel printer ports are widely available in teaching and research laboratories. This paper describes a novel system for controlling any equipment in general, positioning with stepping motors in particular via the parallel Centronics printer port of an IBM PC or compatible. Techniques are presented for exploring the unused parallel port or exploiting the Centronics printer port f...

In this paper we present the development and implementation of an intravenous inf~ision controller system based on fpga’s. The system receives irEformation of an infision drop sensor and controls the drop flow by giving the direction and number of steps of a stepper motor, which compress the drip-feed hose. The system consists of a mixed implementation of sofnvare and hardware. The software was...

Motion control plays a vital role in industrial atomization. Different types of motors AC, DC, SERVO or stepper are used depending upon the application; of these DC motors are widely used because of easier controlling. Among the different control methods for DC motor armature voltage control method using pulse width modulation (PWM) is best one. We can realize the PWM using H-bridge built with ...

This paper shows the potential system benefits of simple tracking solar system using a stepper motor and light sensor. This method is increasing power collection efficiency by developing a device that tracks the sun to keep the panel at a right angle to its rays. A solar tracking system is designed, implemented and experimentally tested. The design details and the experimental results are shown...

The stepper motor is a unit of control system to achieve the goal convenient use and precise control, which greatly facilitates our life improves level modern high-tech industry. In particular, multiple motors may be joined in work together with remote-control program, flexibility applicability equipment. real life, are used more often. For example, 3D printer, using three stepping at same time...

A microprocessor based solar tracking controller is designed and fabricated . In addition to tracking , the controller is capable acquiring photovoltaic and metereological data from a photovoltaic system and controlling battery / load . These features are extremely useful in autonomous PV system installed in remote areas for system control and monitoring. Solar tracking can be achieved in close...

The design idea to implement multi-subdividing drive system for stepping motor based on FieldProgrammable Gate Array chip was proposed in this paper. On a piece of EPF10K10LC84-15, the system module was accomplished using Very-High-Speed Integrated Circuit Hardware Description Language and graph editor. The simulation results were shown on the platform MAX+plus . This method could control the s...
