Software for servo sizing:
Sigma Select
Nicer and more powerfull, but without calculation in doc
Signa Size
etter for initial calculations at least for me…

Induction motors (asinhroni motori)
Good introductory video from Yaskawa, and slides can be found in next video and PDF.
 Servo motor… This is not induction motor |  This is single phase AC motor |
 This is AC motor plate with aditional data on gear box |  I beleive that this is taho but not sure, anyway not a motor plate… |
Now about drives…
Options
- J vs V vs A
- Vector vs VF
- Wiring
- Parametars
Pitanja koja bi mogli da pokrijemo:
Yaskawa is reliable under heavy industrial conditions
Vector controll theory
200/400V naponi i ucestanosti na ulazu

Even Fibonacci numbers – Problem2
Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be:
1, 2, 3, 5, 8, 13, 21, 34, 55, 89, …
By considering the terms in the Fibonacci sequence whose values do not exceed four million, find the sum of the even-valued terms.
program language (python)
In Python :
suma,sumaPre,konačanSuma = 3,2,0
while(sumaPre<4000000):
suma+=sumaPre
sumaPre=suma-sumaPre
if suma % 2 == 0:
konačanSuma+=suma
print (konačanSuma + 2)
second problem is done 🙂 .
problem 3
The prime factors of 13195 are 5, 7, 13 and 29.
What is the largest prime factor of the number 600851475143 ?
thank you for watching.

Multiples of 3 and 5 Problem 1
If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23.Find the sum of all the multiples.
program language (c++,python)
in c++:
int zbir = 0;
int b = 8456;
int i;
int m;
int n;
void setup() {
// put your setup code here, to run onc
Serial.begin(115200);
}
void loop() {
// put your main code here, to run repeatedly:
long suma=0;
Serial.println (i);
for (i =0;i<b;i=i+3) {
suma+=i;
}
for (m =0;m<b;m=m+5) {
suma+=m;
}
for (n =15;n<b;n+=15) {
suma-=n;
}
Serial.println (suma);
Serial.readString();
}
in python:
suma,tri,pet = 0,0,0
b=1000
for i in range (1,b):
if i % 3 == 0:
suma+=i
for m in range (1,b):
if m % 5 == 0:
suma+=m
for n in range (1,b):
if n % 15 == 0:
suma-=n
print (suma)
first problem is done 🙂 .
