DES-YZ01 DC Traction Motor |
|
The motor is developed from the traction motor for Beijing metro vehicle controlled by DC chopper method. Some advanced technology and processes from Japan are adopted in design and manufacture. The armature coils are simplex lap windings and set in cross and upright which result in reducing leakage of permeance and potential of reactance. It main pole coils are arc-pressed and wound on edge and its stator connections are silver-braze soldered. The insulation structure is integrative and its brush holders are fixed on frame head by screws which are not able to be adjusted so that the operation reliability of the motor can be achieved. The motor can also be used for Iran Tehran metro vehicle.
