applied to the output of an 8-steps/revolution motor will result in a 256 step motor. A gear train will also increase the torque of the motor. Some tiny geared steppers are capable of impressive torque. But the tradeoff of course is speed. Geared stepper motors are generally limited to low RPM applications. Backlash is another issue with geared ...

a) Discuss basic principle of diffusion process and its applications in chemical process industry. b) Explain in brief : i) Knudsen diffusion ii) Maxwell's law of diffusion. c) The coefficient of diffusion of HCl gas in air is 0.145 cm2/sec. at 20°C and 1 atm.

The guts of a servo motor (L) and an assembled servo (R) Servos are controlled by sending an electrical pulse of variable width, or pulse width modulation (PWM), through the control wire. There is a minimum pulse, a maximum pulse, and a repetition rate. A servo motor can usually only turn 90° in either direction for a total of 180° movement.

A synchronous motor is designed to develop 2500 hp at 1200 rpm when fed at 60 Hz with a power factor of unity. Considering internal ventilation with an ambient temperature of 40 °C and class H insulation, the temperature rise is, according to Sections I.E and III.C, ϑ w = 90 °C. According to Eq. (41) the bore diameter is

Stainless steel deep groove ball bearings are corrosion resistant when exposed to moisture and several other media.They are available capped (with seals or shields) or open. Open bearings that are also available capped may have recesses in the ring side faces ().These bearings have a lower load carrying capacity than same-sized bearings made of high chromium steel.

Today we will learn about water jet machining and abrasive water jet machining principle, working, equipment's, application, advantages and disadvantages with its diagram. It is one of the most famous non-traditional machining process because it is environment friendly. It uses water jet working as a tool to cut the metal.

The stress intensity and the number of stress events determine the specific energy to achieve a certain product fineness. The number of stress events is a function of mill operating parameters such as grind time, stirrer speed, percent solids and media size. The relationship between stress intensity and specific energy was shown by Kwade as indicated in Figure 10.10.

The applications of Eddy Currents are as follows: 1. Braking Mechanism in Trains. Trains have metal wheels that run over the metallic tracks. When brakes are applied, the metal wheels of the trains get exposed to a magnetic field which induced eddy currents in the wheels. Thus, the trains slow down due to the magnetic interaction between the ...

This manual may be used in a number of ways. For a complete background regarding the application of Hall effect sensors, start with Chapter 1 and read straight through. If a sensing application exists and to determine the applicability of the Hall effect, Chapter 7 might be a good place to start.

the op amp's place in the world of analog electronics. Chapter 2 reviews some basic phys-ics and develops the fundamental circuit equations that are used throughout the book. Similar equations have been developed in other books, but the presentation here empha-sizes material required for speedy op amp design. The ideal op amp equations are devel-

Principle of Operation. The principle of operation of chopper can be understood from the circuit diagram below. The circuit consists of a semiconductor diode, resistor, and a load. For all type of chopper circuit, the output voltage value is controlled by periodic closing and opening of the switches used in the circuit.

Working Principle of LDR. This resistor works on the principle of photo conductivity. It is nothing but, when the light falls on its surface, then the material conductivity reduces and also the electrons in the valence band of the device are excited to the conduction band.

Analog electric meters (i.e., galvanometer, ammeter, voltmeter) operate on the motor principle. Electric motors are an important application of the motor principle. Construction. An electric motor consists of a permanent external field magnet (stator) and a coiled conducting ammeter (rotor) which is free to rotate within the field magnet.
