What is a step, Emoter, and how does it work, this lecture will cope with these questions.
Like other types of matters, the supermoto consists of two main parts.
Stator and wrote, The stator consists of individual sets of coils in contrast to other types of motors,
the rotor in a step motor rotates in the steps.
After each step, the rotor holds itself in position.
These discrete steps are controlled by a proper sequence of pulses on this data calls.
In other words, the stepper motor converts electrical pulses into discrete mechanical movements.
The input pulses determine the number of steps and their directions.
Then with pulse frequency defines the rotation speed.
That's the promoter is usually used to make electronically controlled, precise movements.
It has several applications, especially in DVD players, printers, S.A.C. machines, robotic arms,
just to name a few.
The number of calls will differ based on the type of motor.
But for now, it is enough to understand that in a supermoto there, altor consists of metal poles and
each pole will be attracted by a set of calls in the state.
If you take a look at the coals on the stator, they are arranged in terms of coal powers like A, an
apron B and B and so on.
So each of these coil powers for electromagnets.
When a call gets energized, it acts as a magnet and the Ron Paul gets aligned to it when the rotor
rotates to adjust itself to align with the stator.
It is called one step.
There are mainly three types of a stepper motors based on the rotor construction variable reluctance
supermoto, they have an iron core rotor.
Permanent magnet, the supermoto.
They have a permanent magnet rotor, hybrid, synchronous stepper motor.
They are a combination of variable reluctance and permanent magnets, the promoters.
We can also classify the promoters as unipolar and bipolar based on the type of stator call wiring.
The bipolar stepper motor consists of two sets of coils and usually has four wires, two wires per copy.
The unipolar stepper motor.
Also consists of two couples, but each coil has a center to.
Unipolar supermoto can have six connections, but they often have five as the two center types are tied
together.
We are using the Dash 24 B YJ forty eight, a dash, twenty five, a supermoto in this project, it
is a unipolar stepper motor with five wires, A, B, C, D, and Andersens.
This figure shows the color code of the wires.
The coins should be connected to the firewall quality and they should be driven with zero volts to get
energized.
Instead of transistors, provide the voltage and current for the court's.
There are four different right methods for a supermodel's.
One phase on stepping off by stepping up.
To phase one full step one to phase on half a step, and finally, McQuiston.
Here, I will explain the first three methods to explain these methods, I have simplified the multistage.
In the illustration, each 90 degree turn is representing zero point 45 degree of the rotor rotation
in our remote.
The first method called one phase on stepping or waves stepping in this method, only a single phase
is activated at the time.
When we energize the phase, it attracts Thorold.
We turn off a and turn on the rotor rotates 90 degree.
And so each time only one phase is Energis.
The driver of a form as a forest, that electrical sequence, Toora, Daytrotter.
In the two phase, unmetered.
Two phases are always energized.
Once again, in the illustration below, every 90 degree represents zero point forty five degree rotation.
If most phases A and B are energized, the rotor will be equally attracted to both poles and line up
directly in the middle in sequence.
As the phases are energized, the rotor will rotate to line up between the two energized poles.
The two phase one method has a forest of electrical sequence to rotate the route.
They want to phase one method or half a stepping combines the two previous methods, in this case,
he energized a phase.
There are still lines up at this point.
We keep to a phase and energize the phase.
Now, the Roter is equally attracted to both lines.
In this figure, the router has rotate 45 degree or zero point two hundred and twenty five degree in
the actual mode.
Now we turn off phase A, but leave on phase be.
The motor makes another step.
So on and so forth, we have cut the this angle in half by alternating between one face on and two face
off, half a step, both has an eight step electrical sequence.
How can we implement the one phase on the stepping in the next lecture will cope with this question.
These are our takeaway messages, a stop, a water is usually used to make electronically controlled,
precise movements in this course, we consider three different drive methods for a supermodel's one
phase, unstrapping to phase on a stabbing and one to phase on a stabbing.
Now, the police question.
Which is supermoto driving method provides more accurate control.
