DC Equipment Construction Summary

DC EQUIPMENT CONSTRUCTION DC Generators Stator The stator is the part of a motor or generator that is stationary (refer to Figure 2). In DC machines, the purpose of the stator is to provide the magnetic field. The stator in Figure 2 is provided by a permanent magnet. Field The purpose of the field in a DC machine is to provide a magnetic field for producing either a voltage (generator) or a torque (motor) (refer to Figure 2). The field in a DC machine is produced by either a permanent magnet or an electromagnet. Normally, electromagnets are used because they have an increased magnetic strength, and the magnetic strength is more easily varied using external devices. In Figure 2, the field is provided by the stator. Summary The construction of DC equipment is summarized below. DC Equipment Construction Summary The purpose of the armature is to provide the energy conversion in a DC machine. The purpose of the rotor is to provide the rotating element in a DC machine. In DC machines, the purpose of the stator is to provide the field. The purpose of the field in a DC machine is to provide a magnetic field for producing either a voltage or a torque.
