The intention of this paper is providing an efficient and simple method for control speed of DC motor using pulse width modulation technique. The modulation of pulse is obtained from the LabVIEW - NI ELVIS combination. There are several methods for controlling the speed of DC motors. One simple method is to add series res istance using a rheostat. As considerable power is consumed in the rheostat, this method is not economical. Another method is to use a series switch that can be closed or opened rapidly. This type of control is termed as chopper control. The PWM based chop per circuit smoothly controls the speed of general - purpose DC motors. We used the LabVIEW software and NI ELVIS II DAQ card to control the duty cycle precisely.
