5M2A Traction Motor

5M2A electric traction motor

The motor is ventilated by air which is drawn through the machine by means of a fan at the pinion end; part of the air passes through the armature core ducts, the remainder passing over the surface of the armature and between the poles. The air inlet is at the cummutator end of the motor where a flange is provided for a flexible connection to the body of the vehicle. Air is expelled from the motor at the pinion end through openings in the endshield. These openings are protected by grilles and are shielded by a splash-guard bolted onto the motor frame. On later versions of the motor, the fan is omitted.

8M Traction Motor

 

rotating electric motor 8m

There are eight traction motors fitted to the EMU. The traction motors are identical in construction and operation. The traction motr has 2 main field , namely the automatic variable field coil and the series wound coils. The commutator field is in series with the armature.

The turning force of the motor is fed via the pinion gear and axle gear that reduces the turning speed to the wheel that provide traction for the EMU. The motor is colled by means of forced ventilation from the blower through the air duct.
