A direct current (DC) motor is a fairly simple electric motor that uses electricity and amagnetic field to produce torque‚ which turns the motor. At its most simple‚ a DC motorrequires two magnets of opposite polarity and an electric coil‚ which acts as an electromagnet. The repellent and attractive electromagnetic forces of the magnets provide the torque that causes the DC motor to turn. If you’ve ever played with magnets‚ you know that they are polarized‚ with a positive and a negative side. The

CHAPTER 1: INTRODUCTION 1. Magnetic Abrasive Finishing (MAF) Surface roughness of parts produced by conventional machine tools‚ depends n the machine tool system and the cutting process. It is difficult to produce a smooth surface on complicated profiles at an economic cost by using conventional machining processes. This and the advent of new ‘ difficult-to-machine’ materials like hardened steel‚ nickel‚ cobalt‚ titanium alloys‚ ceramics‚ glass‚ etc.‚ have necessitated the need for

The Physics Of Soccer Soccer is a sport that’s very challenging and during the course I’ve found physics can also be described as challenging. As far as I was concerned soccer and physics were both challenging and that was all they had in common‚ consequently upon researching them both this I found that I was wrong. For me this was nothing new because I’ve found that physics isn’t a subject that can be skimmed‚ but rather it has to be studied to the finest detail. Those small details if missed can

TLE Electron The electron (symbol: e−) is a subatomic particle with a negative elementary electric charge. An electron has no known components or substructure. It is generally thought to be an elementary particle.[2] An electron has a mass that is approximately 1/1836 that of the proton. The intrinsic angular momentum (spin) of the electron is a half-integer value in units of ħ‚ which means that it is a fermion. The antiparticle of the electron is called the positron; it is identical to the

equilibrium is achieved by means of one or more control loops. The use of control loop for maintaining the gap between the shaft and bearing differentiate the active magnetic bearings (AMB) from passive ones. They are in service in such industrial applications as electric power generation‚ petroleum refining‚ machine tool operation and natural gas pipelines BASI C OPERATI ON The typical AMB system diagram is illustrated in above figure.
