About A Textbook of Electrical Technology: Volume 2 AC and DC Machines: AC and DC Machines – Volume 2 Author: B.L. Working of DC Machine. Taylor, "Direct Current Machines", Pitman Pub. 2) An alternating current (AC) is a current that varies with time. Electric Machines General • When a machine is converting electrical energy into mechanical form, it is operating in the MOTORING mode • When a machine converts mechanical energy into electrical form, it is operating in the GENERATING mode • Mechanically, all machines consist of two main parts: STATOR and ROTOR. Download A Textbook of Electrical Technology: Volume 2 AC and DC Machines: AC and DC Machines – Volume 2 in pdf free. The working principle and operation of a DC machine is based on an effect when a current carrying conductor coils laying in a magnetic field, the magnetic field produces a mechanical force on it known as torque which rotates the conductor coils in magnetic field. In fact, the same dc machine can be used interchangeably as a generator or as a motor. BASIC ELECTRICAL AND ELECTRONICS ENGINEERING LECTURE NOTES (AEE018) Prepared By: ... DC MACHINES Principle of operation DC Generator, EMF equation, types, DC motor types, torque equation ... A direct current (DC) is a current that remains constant with time. Say & E.O. Covering electrical technology, the book contains various sections of electrical engineering such as basic electrical engineering, electronics, control systems, devices and communication systems. • The stator is the stationary (non-rotating) part of a machine.
