Overview of Direct Current Machines • Direct-current (DC) machines are divided into dc generators and dc motors. • Most DC machines are similar to AC machines: i.e. they have AC voltages and current within them. • DC machines have DC outputs just because they have a mechanism converting AC voltages to DC voltages at their terminals. • This mechanism is called a commutator; therefore

2000-1-6  Construction of dc Machines: The rotor in a dc machine is called an armature. The armature has cylindrical steel core that is composed of a stack of slotted laminations. Slots in laminations are aligned axially along rotor or shaft. Armature windings are placed in slots. The stator in a dc machine is the field part of the machine.

What is a DC Machine? Basic structure & Equivalent

Although the battery is an important source of DC electric power, it can only supply limited power to any machines. There are some applications where large quantities of DC power are required, such as electroplating, electrolysis, etc. Hence, at such places, DC generators are used to deliver power. Basic Structure of Electrical Machines

Construction of a DC Generator explanation of its

A DC Generator is an electrical device which converts mechanical energy into electrical energy. It mainly consists of three main parts, i.e. magnetic field system, armature and commutator and brush gear. The other parts of a DC Generator are magnetic frame and yoke, pole core and pole shoes, field or exciting coils, armature core and windings, brushes, end housings, bearings and shafts.

2011-4-17  The simplest type of winding construction used in modern DC machines is the simplex lap winding. A simplex lap winding is a rotor (armature) winding consisting of coils containing one or more turns of wire with the two end of each coil coming out at adjacent commutator segments fig. (1.5). The number of current paths in a machine is :

2005-3-9  • DC machines can develop rated torque at all speeds from standstill (locked-rotor) to rated speed. DC machines are easier to analyze than their AC counterparts, although their construction is made rather complex by the fact that they need a commutator, which reverses the direction of currents and fluxes to produce a net torque. • DC motors

Classifications of DC machines : (DC Motors and DC

2021-5-5  Each DC machine can act as a generator or a motor. Hence, this classification is valid for both: DC generators and DC motors. DC machines are usually classified on the basis of their field excitation method. This makes two broad categories of dc machines

Small DC machines (fractional horsepower rat ing) are used primarily as control device-such as tachogenerators for speed s ensing and servomotors for position and tracking, and used in Robots.

AC Motors vs. DC Motors What's the Difference?

2021-5-12  Brushless DC motors are more efficient than those with brushes, but the efficiency gains are primarily at the low-load or no-load areas of the motor performance curve. Other Considerations. For a given amount of mechanical work output, AC motors are usually larger than DC motors, with brushless DC designs being the smallest.
