שאלה לגבי כוח ומהירות במנוע DC עם גיר+פוטנציומטר.

[The arctic wolf]

תודה אלי,
אין כמו הרצאה של איש מכניקה !





אנדריי.

[RoyZ]

אחלה, תודה רבה לכולם על המידע!

אלי, סבבה, אם יש לך תגיד לי.

[RoyZ]

אוקיי, סידרתם לי קצת את הקופסא,

אז אני צריך מייצב מהירות, כזה עם PWM..

משהו כזה:
http://www.electronickits.com/kit/complete/motor/CANUK1102.htm



אז שני דברים..
1. עכשיו אני יכול לקנות את זה משם ובטח יעלה לי הרבה כסף משלוח, לא הצלחתי למצוא משהו דומה לזה אפילו בארץ וגם אם אני אמצא זה בטח יעלה בסוף אותו דבר..
אם מישהו יודע איפה אני יכול למצוא כזה בארץ אני אשמח לדעת..

2. יש מצב שאני יכול לבנות כזה בעצמי נכון? יש שרטוטים של כאלה ברשת כמו זה:


עריכה: מצאתי גם את הרשימה של הרכיבים:
U1: LM324N quad op-amp
U2: 78L12 12 volt regulator
Q1: IRF521 N channel MOSFET
D1: 1N4004 silicon diode
LED1 Red LED
C1: 0.01uF ceramic disc capacitor, 25V
C2-C5: 0.1uF ceramic disk capacitor, 50V
R1-R4: 100K 1/4W resistor
R5: 47K 1/4W resistor
R6-R7: 3.3K 1/4W resistor
R8: 2.7K 1/4W resistor
R9: 470 ohm 1/4W resistor
VR1: 10K linear potentiometer
F1: 3 Amp, 28V DC fast blow fuse
S1: toggle switch, 5 Amps

ופה יש סרטון מעניין של אחד כזה שהוא עובר על הרכיבים גם..
http://www.youtube.com/watch?v=AsMnwAKz2mM

ועל זה יש לי כמה שאלות של מתחיל ואני אשמח אם תעזרו לי, חלק מהן יראו לכם דביליות
אז תסלחו לי..

א. אם לא היתה לי את הרשימה של הרכיבים, יש סיכוי שהייתי מצליח להבין מהם
ומה הערכים שלהם מהשרטוט בלבד? לא.. נכון?


ב. אם אני אצליח להבין מהם כל החלקים שאני צריך (לא אלה בהכרח) ואני אקנה אותם,
נראה לכם שאני אוכל לבנות את זה בעצמי?
יש לי ידע בסיסי באלקטרוניקה ובהלחמות והכל.. למרות שאני מאמין שאני מסוגל לעשות את זה
גם אם אני אצטרך ללמוד קצת על איך לזהות ולחבר את הרכיבים.. (יכול להיות נחמד דווקא)

ג ואחרון. המעגל שמוכרים בא על לוח מודפס אז אני מתאר לעצמי שזה הרבה יותר "נקי"
מלקחת לוח פיתוח ולחבר את כל הרכיבים ושמתחתיו יהיו מלא מלא חיווטים, נכון?
יש דרך אחרת "נקיה" לעשות את זה עם פחות חוטים? לוח פיתוח מסוג מסוים שאני לא יודע עליו
או משהו כזה?

תודה רבה רבה לכולם..

רועי.

[The arctic wolf]

רועי שלום.

א. לפעמים כן אפשר, אם יש מספיק מידע בשרטוט.
ואז אתה פשוט מחפש רכיבים עם ערכים ותכונות מתאימים.

ב. ללא ספק אתה יכול לבנות בעצמך אבל התכונן להשקיע בזה אנרגיה,
לא תמיד הכל עובד כמו שצריך מהפעם הראשונה.

ג.אתה יכול לעשות לוח מודפס בעצמך,חפש במחסן הכלים הודעה של אמנון בנושא,
וגם פה תצתרך להשקיע אנרגייה מאותה הסיבה כמו קודם.

בהצלחה וכל הכבוד על ההשקעה!
אנדריי.
