Abstract

The electric machines have been applied to the industrial and commercial areas for several decades. The high performance of control and fast dynamic response of electric machines can be achieved via motor drive because of high development of semiconductors such as the microcontroller and power transistors. Brushless DC motor (BLDC) and permanent magnet AC synchronous motors drives have many advantages such as high efficiency, small size, less rotor losses, and fast torque response over the induction motor drives. Therefore, this chapter will focus on the design and implementation of a motor drive as well as its realization of control algorithm. At the beginning of chapter, the fundamental of energy conversion for electric machines is introduced. The dynamic model for brushless dc motor is derived and explained in detail in section two. The 120° conduction and 180° conduction of switching device for an inverter are also described and illustrated. The control design of a speed-controlled motor drive is described in section three. The hardware and software design of a motor drive based on a microcontroller is given in section four. The experimental results are also presented and discussed. Finally, a conclusion is made in section five.

27. The design and implementation of windowing interface arm strength training machine.

Author

Abstract

Most of the conventional exercise apparatus use the iron or aluminum for weight lifting. Without assistance of professional trainer or qualified rehabilitation therapist, physical injury could be occurred when exercises or rehabilitation therapy improperly proceed. This paper presents a friendly windowing interface for an arm strength training machine based on the ARM controller, in such a way to reduce the occurrence of improper operation of exercise machine by real time monitoring. The system hardware consists of a LCD touch panel, universal asynchronous receiver and transmitter (UART) communication, ADC converter, Cortex-M3 controller, and a PMSM motor drive which is basically realized by a microcontroller for simulating the weight stack. The system software for windowing interface is developed under Cortex M3 development environment and written in C language. It is helpful to implant and expand the whole system to mobile phone in the future because most of the mobile telecommunication products are based on the ARM core structure. The firmware of motor drive is programmed based on the MPLAB integrated development environment tool by Microchip technology incorporate. Finally, a prototype of windowing interface arm strength training machine is realized and demonstrated. The experimental results show the feasibility and fidelity of the complete designed system.

28. The design and implementation of the BLDC motor drive for a washing machine.

Author

Ho, Tze-Yee, Mu-Song Chen, Jia-Shen Lin, and Po-Hung Chen

Abstract

This paper presents the brushless DC (BLDC) motor drive with direct torque control (DTC) for a washing machine over variable speed range. The system hardware and software programming are analyzed and designed. The flux controller and torque controller are derived and realized accordingly. A prototype of BLDC motor drive based on the DSP controller with DTC control is implemented and validated by the exhibition of waveforms measurement for currents, torque, flux linkage, and speed. The performance of the BLDC motor drive employing DTC is compared with that of BLDC utilizing the PI current control. The simulations are carried out prior to realization of the system implementation. The experimental results not only verify the feasibility of designed system but also demonstrate that BLDC with DTC control has superior characteristics than that with PI current control.
