Some of these are given special names. A machine is a piece of equipment which uses electricity or some other form of power to perform a particular task. Definition: Electric motor is the electro-mechanical machine which converts the electrical energy into mechanical energy. We use dozens of devices in which electric motors are used, such as, refrigerators, mixers, fans, washing machines, computers, etc. This simple rule is called Fleming’s right-hand rule.”. A galvanometer is an instrument that is used to detect the presence of a current in a circuit. This is called the motor effect. DC Motor Operation This is an active graphic. In a DC motor, the input electrical energy is the direct current which is transformed into the mechanical rotation. Motion that changes the orientation of a body is called rotation. Based on the objects in contact we give these contact forces different names. Basic Mechanics. Fleming’s right-hand rule states that “Stretch the thumb, forefinger and middle finger of right hand so that they are perpendicular to each other (see the image given below). All considerations of motion are addressed by mechanics, as well as the transmission of forces through the use of simple machines. Physics Notes for UPSC IAS Prelims (Part I).
