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.

    1. Historically, PMs could not be made to retain high flux if they were disassembled; field windings were more practical to obtain the needed amount of flux.

    2. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current flow in part of the motor. A characteristic of series motors is the motor develops a large amount of starting torque.

    3. A DC motor is any of a class of rotary electrical machines that converts direct current electrical energy into mechanical energy. Brijmohan Paliwal Apr 09,

    4. For simplicity of explanation, the stator is represented by permanent magnets in the following illustration.
