Brushed dc coreless motors have air core armatures, so they can reach high speeds in a matter of only milliseconds with about 90% efficiency.
Compared to conventional iron-core, brush-type dc motors, the ironless types have no iron losses, low friction, and acceptable thermal dissipation, which make them extremely efficient. The design of the low-inertia rotor is the key to rapid acceleration and fast reaction time. In addition, their linear torque-speed characteristics fit well with simple drive circuits. They should be especially considered when designing low-power, battery-operated equipment, such as pagers, model trains, and hand-held tools.






The name coreless (or ironless) refers to the motor construction. These motors, unlike most other types of motors, have no iron core-armature in the rotor. Special skewed or honeycomb patterns are used to wind the rotor coils to ensure mechanical strength and evenly distribute the magnetic flux for all coils in the rotor winding. This results in maximum torque and smooth rotation. Because it has no iron core to support the windings, they are typically held together by epoxy. Some designs use a plastic frame. Depending on the rotor geometry, ironless motors can be cylindrical or disc shaped. The stator is often made of samarium-cobalt, or Neodymium magnets.
