Section 4 The Starting System - Autoshop 101
www.autoshop101.comArmature coil wires - The coil wires in a PS starter armature are square in cross-section. •More compact winding than round cross-section wires •Greater output torque Surface commutator - The square shape of the armature conductors allow the surface of the armature to act as a commutator. Field coils - Conventional starters use field coils.

pages.mtu.eduThe rotor contains the armature winding, which is the high-power winding of the DC machine. The slots in the lamination provide space for the armature coil. When operating as a generator, the armature winding is rotated through the field, generating a DC voltage that is delivered to the load. For motor operation, the armature winding

AC Generators - EandM
www.eandm.comAn armature is any number of conductive wires wound in loops which rotates through the magnetic field. For simplicity, one loop is shown. When a conductor is moved through a magnetic field, a voltage is induced in the conductor. As the armature rotates through the magnetic field, a voltage is generated in the armature which causes current to flow.
DC Motors
dept.ru.ac.bdwinding is connected in series with the armature. Therefore, series field winding carries the armature current. Since the current passing through a series field winding is the same as the armature current, series field windings must be designed with much fewer turns than shunt field windings for the same mmf.
Open Circuit Characteristics Of A DC Generator Aim 1 Theory
www.ee.iitb.ac.inIf the armature terminals are left open and the armature is rotated at constant speed, then the induced emf in the armature is given by E= K 1˚ (1) where K 1 is a constant. In other words the induced emf is directly proportional to the airgap ux. Flux depends on the magneto-motive force (MMF) provided by the current in the eld winding. That is ...
II. Synchronous Generators
www.uotechnology.edu.iqArmature Reaction in Synchronous Machines . Armature reaction. refers to • the influence on the magnetic field in the air gap when the phase windings a, b, and c on the stator are connected across a load. • The flux produced by the armature winding reacts with the flux set up by the poles on the rotor, causing the total flux to change.

Synchronous Machines
www.courses.ece.vt.eduAs the rotor moves within the stator, the field induces voltage in the armature winding of the machine. This voltage is called the generated voltage in a generator and the back EMF in a motor. Its magnitude is directly proportional to the speed of the rotor, the strength of the field, and the effective turns of the armature.
Synchronous Machines
www.iitp.ac.inIStator (armature) is connected to a three phase AC supply. IRotor ( eld winding) is connected to a DC supply. Unlike three phase induction motors and DC motors, synchronous motors are not self-starting. let us consider a 4-pole synchronous machine.

www.brown.eduwell the armature winding of a generator is cooled has a significant influence on the overall size of a synchronous generator. The cooling of the armature winding is dependent on a number of factors: cooling medium (air, hydrogen, water); insulation thickness; and overall electrical losses (1 2 R + load loss). As Figure 5 illustrates,
