# Converting a DCM Motor

Schematic Diagrams      Comments Off on Converting a DCM Motor

We recently bought a train set made by a renowned company and just couldn’t resist looking inside the locomotive. Although it did have an electronic decoder, the DCM motor was already available 35 (!) years ago. It is most likely that this motor is used due to financial constraints, because… Read more »

# Circuit Diagram for DC Motor Control by A. Collins

Schematic Diagrams      Comments Off on Circuit Diagram for DC Motor Control by A. Collins

A DC motor is an electric motor that runs on direct current (DC) electricity. Every DC motor has six basic parts — axle, rotor (a.k.a., armature), stator, commutator, field magnet(s), and brushes. The geometry of the brushes, commutator contacts, and rotor windings are such that when power is applied, the… Read more »

To wire a DC Motor, you will need following parts: a DC motor which should be rated for 6 to 9v and 100 to 500 mA; one 0.1 uF capacitor which will be attached close to the motor terminals and helps smooth out electrical fluctuations generated by the motor; one… Read more »

# Permanent Magnet DC Motor Equivalent Circuit Diagram

Schematic Diagrams      Comments Off on Permanent Magnet DC Motor Equivalent Circuit Diagram

A permanent magnet DC (PMDC) motor consists of a permanent magnet stator and armature windings in the rotor. The armature winding is supplied with a DC voltage that causes a DC current to flow in the windings. Interaction between the magnetic field produced by the armature current and that of… Read more »
