ABSTRACT

In this fast growing age of science and technology we want make a projects which is advantageable, beneficial in todays life with having a low cost.
Before selecting this project collection of technical data and market survey should be done by market survey we make it sure that all the components of this project are easily available in the market.
Now a day in industries, windings of motor is wounded manually. It is too much time consuming process and all required high skilled workers. In our Project, we are going to design a machine which can automatically wound stator coils of motors. There are various types of motors are used in market. So there are different types of winding to be wounded.
One has to design such a machine which can be used for different types of winding. In this Project, servo motor will be used to rotate bobbins. In this motor, no. of revolution can be controlled easily. Use of automatic wound machine will reduce time consumption of manufacturing process of motor. So it will increase rate of production and also maintain quality standards.

1. Introduction

In Industries, Old Conventional method is used for winding of motor. This process has too much time consumption. In this process, high skilled manpower is also required. But still its efficiency and quality is low. And for different types of motors, windings are different also. So our team is going to make such a machine which can wound coils automatically on bobbins.
This is a relatively new but highly upgraded machine because in industries, many types of motors are available and all these motors have different type of windings. So our machine can be used for any type of winding of any motor.
In this machine, we are going to use servo motor as main motor. Reason for choosing servomotor is its accuracy and smooth revolution control. Servo motor Gives smooth speed control and also gives smooth revolution control. This Motor is reliable so we are going to use this motor.
This servo motor will be used for rotating bobbins. Stepper motor is used for horizontal displacement of coil selecting unit.
PLC logic will be used for this project. PLC unit will receive input digital data. PLC will perform output on this input data. PLC will Control all the units.
HMI Unit will be used for input data. HMI will give data to PLC and then PLC will Execute Program as per input and we will get output

3.1 Servo Motor
A servomotor is closed-loop servomechanism that uses position feedback to control its motion and final position. The input to its control is some signal, either analogue or digital, representing the position commanded for the output shaft.
The motor is paired with some type of encoder to provide position and speed feedback. In the simplest case, only the position is measured. The measured position of the output is compared to the command position, the external input to the controller. If the output position differs from that required, an error signal is generated which then causes the motor to rotate in either direction, as needed to bring the output shaft to the appropriate position. As the positions approach, the error signal reduces to zero and the motor stops.
The very simplest servomotors use position-only sensing via a potentiometer and bang-bang control of their motor; the motor always rotates at full speed (or is stopped). This type of servomotor is not widely used in industrial motion control, but it forms the basis of the simple and cheap servos used for radio-controlled models.
More sophisticated servomotors use optical rotary encoders to measure the speed of the output shaft and a variable-speed drive to control the motor speed. Both of these enhancements, usually in combination with a PID control algorithm, allow the servomotor to be brought to its commanded position more quickly and more precisely, with less overshooting

3.1 Stepper Motor
A stepper motor or step motor or stepping motor is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor’s position can then be commanded to move and hold at one of these steps without any feedback sensor (an open-loop controller), as long as the motor is carefully sized to the application in respect to torque and speed.
Switched reluctance motors are very large stepping motors with a reduced pole count, and generally are closed-loop commutated.DC brushed motors rotate continuously when DC voltage is applied to their terminals. The stepper motor is known by its property to convert a train of input pulses (typically square wave pulses) into a precisely defined increment in the shaft position. Each pulse moves the shaft through a fixed angle.
Stepper motors effectively have multiple “toothed” electromagnets arranged around a central gear-shaped piece of iron. The electromagnets are energized by an external driver circuit or a micro controller. To make the motor shaft turn, first, one electromagnet is given power, which magnetically attracts the gear’s teeth. When the gear’s teeth are aligned to the first electromagnet, they are slightly offset from the next electromagnet. This means that when the next electromagnet is turned on and the first is turned off, the gear rotates slightly to align with the next one. From there the process is repeated. Each of those rotations is called a “step”, with an integer number of steps making a full rotation. In that way, the motor can be turned by a precise angle

3.1 HMI
The human–machine interface is the part of the machine that handles the human–machine interaction. Membrane switches, rubber keypads and touchscreens are examples of the physical parts of the Human Machine Interfaces which we can see and touch.
In complex systems, the human–machine interface is typically computerized. The term human–computer interface refers to this kind of system. In the context of computing the term typically extends as well to the software dedicated to control the physical elements used for human-computer interaction.
The engineering of the humans–machines interfaces is enhanced by considering ergonomics. The corresponding disciplines are human factors engineering and usability engineering which is part of systems engineerings.
Tool used for incorporatings human factors in the interface design are developed based on knowledge of computer science, such as computer graphics, operating systems, and programming languages. Nowadays, we use the expression graphicals user interface.
