Drum collector motor

As drum commutator motors designate model railroaders a classical three-pole Märklin- round motors with spur gear that it is both universal motor as well as a DC motor are. The conversion between the two types of motor is carried out simply by exchanging the pole bracket. Drum collector motors from Märklin each have two carbon brushes in an angular design.

The drum collector was used in most of the locomotive models built between the mid- 1970s and the end of the 1990s . In addition, Märklin converted some of the older models that were previously supplied with disc collectors to the drum collector motor.

The Swiss manufacturer HAG also uses very similarly constructed engines .

In addition, the drum collector motor is also available in a special form with a five-pole armature, which is referred to as a "high-performance motor" and is used in regulated digital models. Märklin offers conversion kits for older models with the classic three-pole drum and disc collectors in order to convert them to the high-performance drive. In addition to the new engine parts, the conversion kits also contain a digital decoder. The high-performance motors are only available with permanent magnets.

Another special form existed for a limited period of time under the designation "5-star drive", in which a five-pole armature was also used, but the field coil was retained, so the motor remained an all-current motor . However, this design found limited use, not least because of the short construction time, and was then replaced by the high-performance engine.

Other standard motor types from Märklin are the disc collector motor and the C-sine motor .
