The DES-ZDY101 motor acts as traction motor for DK20 metro vehicle. The magnet frame is rolling formed and welded with Q235-A steel plate. At the commutator end, there are windows at the each side of the frame, so serviceman can check the working conditions of brushes and commutator, replace the brushes and maintenance the commutator. At the other end, there are outlets, an aluminum casting alloy centrifugal fan is equipped on the armature shaft. The magnetic pole coils are integrative structure.
