1
00:00:01,160 --> 00:00:07,000
What is a step, Emoter, and how does it work, this lecture will cope with these questions.

2
00:00:09,000 --> 00:00:14,250
Like other types of matters, the supermoto consists of two main parts.

3
00:00:15,430 --> 00:00:24,250
Stator and wrote, The stator consists of individual sets of coils in contrast to other types of motors,

4
00:00:25,000 --> 00:00:29,170
the rotor in a step motor rotates in the steps.

5
00:00:29,410 --> 00:00:32,890
After each step, the rotor holds itself in position.

6
00:00:34,190 --> 00:00:40,730
These discrete steps are controlled by a proper sequence of pulses on this data calls.

7
00:00:42,460 --> 00:00:49,660
In other words, the stepper motor converts electrical pulses into discrete mechanical movements.

8
00:00:50,930 --> 00:00:55,220
The input pulses determine the number of steps and their directions.

9
00:00:56,420 --> 00:00:59,960
Then with pulse frequency defines the rotation speed.

10
00:01:03,820 --> 00:01:09,820
That's the promoter is usually used to make electronically controlled, precise movements.

11
00:01:10,720 --> 00:01:19,150
It has several applications, especially in DVD players, printers, S.A.C. machines, robotic arms,

12
00:01:19,570 --> 00:01:20,470
just to name a few.

13
00:01:25,650 --> 00:01:29,910
The number of calls will differ based on the type of motor.

14
00:01:31,300 --> 00:01:37,840
But for now, it is enough to understand that in a supermoto there, altor consists of metal poles and

15
00:01:37,840 --> 00:01:41,230
each pole will be attracted by a set of calls in the state.

16
00:01:43,830 --> 00:01:51,780
If you take a look at the coals on the stator, they are arranged in terms of coal powers like A, an

17
00:01:51,780 --> 00:01:54,780
apron B and B and so on.

18
00:01:55,860 --> 00:01:59,850
So each of these coil powers for electromagnets.

19
00:02:02,070 --> 00:02:10,080
When a call gets energized, it acts as a magnet and the Ron Paul gets aligned to it when the rotor

20
00:02:10,080 --> 00:02:13,680
rotates to adjust itself to align with the stator.

21
00:02:15,000 --> 00:02:16,590
It is called one step.

22
00:02:22,010 --> 00:02:28,250
There are mainly three types of a stepper motors based on the rotor construction variable reluctance

23
00:02:28,280 --> 00:02:31,340
supermoto, they have an iron core rotor.

24
00:02:32,370 --> 00:02:34,260
Permanent magnet, the supermoto.

25
00:02:35,250 --> 00:02:40,200
They have a permanent magnet rotor, hybrid, synchronous stepper motor.

26
00:02:41,220 --> 00:02:46,440
They are a combination of variable reluctance and permanent magnets, the promoters.

27
00:02:48,020 --> 00:02:55,400
We can also classify the promoters as unipolar and bipolar based on the type of stator call wiring.

28
00:02:59,080 --> 00:03:06,300
The bipolar stepper motor consists of two sets of coils and usually has four wires, two wires per copy.

29
00:03:11,290 --> 00:03:12,790
The unipolar stepper motor.

30
00:03:13,920 --> 00:03:17,790
Also consists of two couples, but each coil has a center to.

31
00:03:19,050 --> 00:03:26,610
Unipolar supermoto can have six connections, but they often have five as the two center types are tied

32
00:03:26,610 --> 00:03:27,070
together.

33
00:03:31,000 --> 00:03:39,160
We are using the Dash 24 B YJ forty eight, a dash, twenty five, a supermoto in this project, it

34
00:03:39,160 --> 00:03:45,040
is a unipolar stepper motor with five wires, A, B, C, D, and Andersens.

35
00:03:45,910 --> 00:03:48,460
This figure shows the color code of the wires.

36
00:03:50,420 --> 00:03:57,860
The coins should be connected to the firewall quality and they should be driven with zero volts to get

37
00:03:57,860 --> 00:03:58,580
energized.

38
00:03:59,570 --> 00:04:04,040
Instead of transistors, provide the voltage and current for the court's.

39
00:04:08,890 --> 00:04:11,830
There are four different right methods for a supermodel's.

40
00:04:13,160 --> 00:04:16,610
One phase on stepping off by stepping up.

41
00:04:18,070 --> 00:04:24,150
To phase one full step one to phase on half a step, and finally, McQuiston.

42
00:04:25,300 --> 00:04:33,700
Here, I will explain the first three methods to explain these methods, I have simplified the multistage.

43
00:04:34,940 --> 00:04:42,800
In the illustration, each 90 degree turn is representing zero point 45 degree of the rotor rotation

44
00:04:42,920 --> 00:04:43,760
in our remote.

45
00:04:46,710 --> 00:04:54,510
The first method called one phase on stepping or waves stepping in this method, only a single phase

46
00:04:54,510 --> 00:04:55,910
is activated at the time.

47
00:04:56,900 --> 00:05:00,260
When we energize the phase, it attracts Thorold.

48
00:05:01,630 --> 00:05:06,340
We turn off a and turn on the rotor rotates 90 degree.

49
00:05:07,330 --> 00:05:11,440
And so each time only one phase is Energis.

50
00:05:12,570 --> 00:05:18,450
The driver of a form as a forest, that electrical sequence, Toora, Daytrotter.

51
00:05:22,870 --> 00:05:24,610
In the two phase, unmetered.

52
00:05:26,410 --> 00:05:28,840
Two phases are always energized.

53
00:05:30,720 --> 00:05:38,070
Once again, in the illustration below, every 90 degree represents zero point forty five degree rotation.

54
00:05:38,910 --> 00:05:47,400
If most phases A and B are energized, the rotor will be equally attracted to both poles and line up

55
00:05:47,400 --> 00:05:50,010
directly in the middle in sequence.

56
00:05:50,250 --> 00:05:57,180
As the phases are energized, the rotor will rotate to line up between the two energized poles.

57
00:05:57,990 --> 00:06:04,140
The two phase one method has a forest of electrical sequence to rotate the route.

58
00:06:10,800 --> 00:06:18,120
They want to phase one method or half a stepping combines the two previous methods, in this case,

59
00:06:18,250 --> 00:06:19,690
he energized a phase.

60
00:06:20,130 --> 00:06:22,430
There are still lines up at this point.

61
00:06:22,560 --> 00:06:25,620
We keep to a phase and energize the phase.

62
00:06:26,250 --> 00:06:29,850
Now, the Roter is equally attracted to both lines.

63
00:06:29,850 --> 00:06:38,100
In this figure, the router has rotate 45 degree or zero point two hundred and twenty five degree in

64
00:06:38,100 --> 00:06:38,890
the actual mode.

65
00:06:39,840 --> 00:06:43,920
Now we turn off phase A, but leave on phase be.

66
00:06:44,370 --> 00:06:46,230
The motor makes another step.

67
00:06:47,250 --> 00:06:55,380
So on and so forth, we have cut the this angle in half by alternating between one face on and two face

68
00:06:55,380 --> 00:06:59,670
off, half a step, both has an eight step electrical sequence.

69
00:07:03,760 --> 00:07:09,430
How can we implement the one phase on the stepping in the next lecture will cope with this question.

70
00:07:13,980 --> 00:07:20,490
These are our takeaway messages, a stop, a water is usually used to make electronically controlled,

71
00:07:20,490 --> 00:07:27,630
precise movements in this course, we consider three different drive methods for a supermodel's one

72
00:07:27,630 --> 00:07:34,560
phase, unstrapping to phase on a stabbing and one to phase on a stabbing.

73
00:07:37,990 --> 00:07:39,160
Now, the police question.

74
00:07:41,400 --> 00:07:45,560
Which is supermoto driving method provides more accurate control.
