Brush DC motor Basics
Construction of Portescap motors with
iron less rotor DC motors
All DC motors, including the ironless rotor motors, are composed of three principle sub assemblies:
The stator consists of the central, cylindrical permanent magnet, the core which supports the bearings, and the steel tube
which completes the magnetic circuit. All three of these parts are held together by the motor front plate, or the mounting
plate. The magnetic core is magnetized diametrically after it has been mounted in the magnetic system
The Brush Holder Endcap is made of a plastic material. Depending on the intended use of the motor, the brush could be
of two different types:
•
•
Of the three sub-assemblies, the one that is most characteristic of this type of motor is the ironless, bell-shaped rotor.
There are primarily four different methods of fabricating these ironless armatures utilized in present-day technology.
A — In the conventional way, the various sections of the armature are wound separately, then shaped and assembled
to form a cylindrical shell which is glass yarn reinforced, epoxy resin coated, and cured. It is of interest to note the
relatively large coil heads which do not participate in the creation of any torque.
