يعرض القسم النظري مبدأ عمل دارة تحكم بالموقع باستخدام محرك تيار
المستمر نظرا لأن المحرك المستمر هو العنصر الأساسي الذي يقوم بدوران
بزاوية معينة و بالتالي نقل الحركة إلى علبة السرعة التي تقوم بتخفيض سرعة
دوران المحرك للتحكم بالمقاومة المتغيرة التي تقوم بضبط التوتر Vb لكي
يصبح مساويا للتوتر Vr .

The theoretical section presents the principle of
operation of an on-site control circuit using a DC
motor, as the continuous motor is the main element
that rotates at certain angle and thus moves the
action to the gearbox which reduces the engine's
rotational speed to control the variable resistance
which adjusts the voltage Vb to be equal to the
voltage Vr
The Practical section displays the results.

This research aims to study the effect of rotation speed and armature
current density or load current of micro dc motors on the commutation
current, especially on the final phase where electrical spark occurs on the
motor collector. A relationship
The consumption of power in the industrial field almost reaches approximately 40%
of the total generated power. One kind of useless consumption of power is the losses in the
electrical motors starting. The impact of the losing power might be ignore
A lot of researches studies robot arms and the ability of controlling it to track targets
which depends on the type of motors used, DC motors or servo motors. In addition to
response time that DC and motor can give as a physical structure.
