Abstract: The presented paper is concerned with the speed controlling of dc motor by using embedded system, which is easy to use and provide us very high accuracy. Here we have compared the different type of techniques which are used to control the speed of DC motor. We have used CMOS 8-bit microcontroller with 8K bytes in system programmable flash AT895S2. The most important advantage of a DC motor is that we can vary the relationship of speed-torque as per our requirement & for that purpose we have use a simple technique which is known as Pulse Width Modulation, which is used to produce low and high pulses. The pulses produce is the cause of changing speed of motor. Therefore to achieve this we have use a microcontroller (AT89S52), which can be programmable to set the speed by changing the time period of duty cycle in the code. Keywords: embedded, microcontroller, Pulse Width Modulation (PWM), speed-torque, CMOS.

Speed Control of Direct Current Motors
Zenodo (CERN European Organization for Nuclear Research), 2022
Direct current (DC) motors are used in variable-speed drives to produce a high starting torque, and provide speed control over a wide range of speed. Controlled rectifiers are popularly employed in the speed control of DC motors. In this paper, the speed control of separately excited dc motor, using single-phase, full-wave, fully-controlled rectifier was investigated. Controlled rectifiers were used to produce variable DC output voltages from a fixed alternating current (AC) voltage. Since the armature voltage (Va) of a DC motor is the output of a single-phase controlled rectifier, it was varied by varying the delay or firing angle (αa) of the rectifier. The field circuit also requires a rectifier to control the field current (If) or flux by varying the firing angle (αf). In this paper, the motor speed equations were derived. The output equations of the rectifiers were also derived and incorporated into the motor speed equations. The graphs generated from these equations show clearly how the speed of the DC motor varies with the output voltage or current of the controlled rectifiers. Thus, motor speed, being a function of the armature voltage (Va), or the field current (If) was controlled. This paper demonstrates the control strategies of a separately excited dc motor, using singlephase controlled rectifiers.
