However, large PMs are costly, as well as dangerous and difficult to assemble; this favors wound fields for large machines. Advantages of a brushed DC motor include low initial cost, high reliability, and simple control of motor speed. The sequence of turning a particular coil on or off dictates what direction the effective electromagnetic fields are pointed. Delmar, Cengage Learning, Which type are these and what is the difference. Disadvantages are high maintenance and low life-span for high intensity uses. Very small brushes may rely on sliding contact with a metal brush holder to carry current into the brush, or may rely on a contact spring pressing on the end of the brush. In diesel electric locomotives they also use their DC motors as generators to slow down but dissipate the energy in resistor stacks. Namespaces Article Talk. A DC motor is any of a class of rotary electrical machines that converts direct current electrical energy into mechanical energy.
There are 3 main types of DC motor that are available: Series, Shunt and Compound.
These terms relate to the type of connection of the field windings with. Before variable-voltage supplies became readily available, most d.c.

The shunt-connected motor offers good speed regulation. DC Motor Characteristics As you already know, there are two electrical elements of a DC motor, the field windings and the armature.
Coupled with a DC drive, they. Series wound DC motors are best for applications that require high of compound wound DC motors, depending on whether the shunt field. 6 days ago A SIMPLE explanation of the different types of DC Motors. Shunt wound DC motor; Series wound DC motor; Compound wound DC motor.
Delmar, Cengage Learning, An advantage to a separately excited shunt field is the ability of a variable speed drive to provide independent control of the armature and field. Covariant formulation Electromagnetic tensor stress—energy tensor Four-current Electromagnetic four-potential.
