Short Definition

A type of Direct Current Motor

A type of Direct Current motor, which is different in construction than that of the usual can motor. Instead of a large rotating iron armature, it is made from lightweight material with the magnet wire wound around it. They are designed for rapid acceleration.

These motors should not be used on a DCC system without a decoder installed. They will overheat when operated in zero stretching modes. This is due in part to their low impedance/inductance, which makes them look almost like a short circuit to a high frequency signal such as the DCC waveform. This will allow a lot of current to flow. The excessive current will result in the destruction of the motor, very quickly.
