996 Electrical Technology 29.1. Motor Principle An Electric motor is a machine which converts electric energy into mechanical energy. Its action is based on the principle that when a current-carrying conductor is placed in a magnetic field, it experiences a mechanical force whose direction is given by Fleming’s Left-hand Rule and whose
3 maj 2019 · 1- Most of the electrical machines in service are AC types. 2- DC machine are of considerable industrial importance. 3- DC machine mainly used as DC motors and the DC generators are...
Basic DC Motors • The most simplest DC motor has a stationary set of magnetic poles. This is called the stator. The stator can use permanent magnets or electro-magnets which creates a stationary magnetic field. The stator can have multiple magnetic fields. • The DC motor has a rotating set of electro-magnetic poles called the rotor.
When a d.c. motor is used in driving system, its basic operational characteristics are determined by both the values of the resisting torque TL created by the load, and the electromechanical properties of the motor itself. In the steady-state operation of the drive, it has been shown in Chapter Ten, Section, that the value of the torque Tm.
DC Motors book - Free download as PDF File (.pdf), Text File (.txt) or read online for free. The document discusses direct current (DC) motors. It describes how back electromotive force (EMF) regulates the current in a DC motor to meet load requirements.
theory, terminology, and application. The handbook includes information on alternating current (AC) and direct current (DC) theory, circuits, motors, and generators; AC power and reactive components; batteries; AC and DC voltage regulators; transformers; and electrical .
Whenever a machine converts electrical energy which is DC in nature, into mechanical energy, it is called a DC Motor. EE. Faraday’s Laws of Electro magnetic Induction. Whenever a conductor cuts the flux of a magnetic field, an emf is produced in the conductor.
