The type described above would be termed a ztaj speed resolver; that is, the output signal goes through only one sine wave as the rotor goes through mechanical degrees. This change is directly proportional to the angle which the rotor has been moved through. Gain, therefore is a measure of the amplification of the input signal. The encoder’s shaft is rotated and an output signal results which is proportional to distance i. Because of the strong field on one side of the coil and the weak field on the other side, the coil will be pushed into the weaker field and, because the armature coil is free to rotate, it will rotate.

If the induction motor ran at synchronous speed, there would be no relative motion and no torque would be produced. This is an example of a “closed loop” drive.

In addition, increasing gain adds components, cost, complexity. During this period, defense spending in regions such as the Middle East, the Gulf and the Caspian, which are very important in our operations, maintained their rapid upward trend.


The aswlsan channel version provides a signal relationship to obtain motion direction i. A low torque to inertia ratio limits this motor type to less demanding incrementing start-stop applications. This type of speed control is adequate for many applications If smoother speed is desired, an electronic network may be introduced. Ripple may be termed voltage ripple or tachometer ripple.

Staj sresince yrtlen almalar With PWM techniques, power is regulated by applying pulses of variable width, i. However, one major difference is the synchronous motor uses a permanent magnet rotor and the induction motor uses iron bars arranged to resemble a squirrel cage.

Published on Nov View wselsan Download 9. A reference signal is applied onto the primary the rotorthen via transformer action this is coupled to the secondary. The first assumption is that power is applied onto the motor and the second is that the motor shaft is free to rotate.

For very rapid start-stop positioning applications, a larger motor would be used to keep temperatures within design limits.

The main topics on our agenda in will be to increase efficiency in order to ensure sustainable growth, to expand our product range in our existing fields of activities, to focus on new areas of activity, to raise the share of exports in our total sales, to further exploit our know-how in civil areas, to enable the continuity of our investments and to pursue investment opportunities abroad.

A command signal which is issued from the user’s interface panel comes into the servo’s “positioning aselaan.

But suppose the first car slows down. In the summer practice program the students put their theoretical values learned in previous courses into practice by the help of engineers and technicians who are respons responsibl iblee from from the process processes es in the organi’ organi’ati ation.

Vector control is implemented using a microprocessor based system that has a mathematical model of the motor in memory and a position transducer on the motor to indicate rotor. This power is supplied to the servo control amplifier from the “power supply” which simply converts AC power into the required DC level. As implied earlier, in order for a voltage to be induced into a conductor, there must be a relative motion between the conductor and the magnetic lines of flux.

Especi Especially ally for the product production ion techni ues the summer practice program is much more useful.

The faster the shaft is aselasn, the larger the aselsam of voltage developed i. This other “device” is either a tachometer, resolver or encoder providing a signal which is “sent back” to the controller.

While the synchronous motor may start a high rsporu load, it may not be able to accelerate the load enough to pull it into synchronism. In the following, each of these devices will be defined and the basics explored. Thus for the linear type of control, power is delivered constantly, not in discrete pulses like the SCR control.

And in order that the machine will perform without excessive overshoot, settle within adequate time periods, and have minimum steady state sta, the servo must be adjusted or compensated. Also the polarity of the electro magnet can easily be reversed. As we apply a load, the rotor begins to slow down which creates slip. Internally, a “signal” winding rotor revolves inside a fixed stator.

One type of semiconductor is the SCR silicon controller rectifier which will be connected to the AC line voltage. On the side of the coil where the lines of flux oppose each other, the magnetic field will be made weaker.
