Three phase traction motor type 6 FRA 6068 is used on WAG9/ WAP7 class of locomotives. It is an asynchronous 6 pole squirrel cage rotor motor which operates by a three phase supply fed by 3 phase converter. It is forced air cooled through a vent in the non-drive end housing. The traction motor blower supplies filtered air to cool the traction motor. The flexible bellows connect the traction motor vent and the air outlet of the blowers on the locomotive under frame. The rotational force from the traction motor is transmitted to the gear box by a pinion drive coupling. The opposite end of rotor shaft is enclosed by an end plate.
