First of all it’s a 6 pole, 650 KW, DC traction motor termed as TMHS15250A. Secondly the test being shown in the video is called “Wheeler Test” which is generally a no load test. Purpose of this test is to observe any abnormal noise if there is any and to check bearing temperature rise which should not exceed over 40 deg C. The input supply to the traction motor is generally < 100 Vdc. Kindly correct for the same in description of the video.
These traction motors runs on 750V DC and 900A continuous power delivery and yes it's a HS15250A traction motor used in WAP4 locos and many other older loco from before 1999
Informative little video. But 25kv as you have in description is not correct. Traction motors dont run at such a high voltage. At 25kv motor winding insulation will very likely fail. These motors usually run at less than 1kv. Thank you.
The 25kv AC supply is stepped down. The traction motor shown in the video runs on 750V DC supply. They are used in the WAP 1,WAP4 and WAM series and many old locomotives. From the 2000 onwards AC traction motors are used in indian railways which works on 2180V supply. Still the remaining Wap4's traction motors runs on 750v DC supply.
Curios why they tested with dry gears, they run in an oil bath, and the new locomotives use AC traction motors that weigh around 15,000# pounds, the DC motors are a bit lighter at 10,000#
@@amritmahotsav3378 why would they go from DC to AC, back to DC, I was the crane tech for the KCS Shreveport engine shop, they were just starting to get AC motors in, and were overloading the crane and one guy lost a thumb over it...
Well it is a DC Traction motor because in any locomotive the AC is converted to DC using a rectifier. In electric loco the high voltage AC is first stepped down to low voltage AC using a step down transformer which is then converted to DC using a rectifier. So the DC finally drives the DC motor and in modern locos we also have inverters which convert the current into 3 phase DC for the 3 phase DC motor. So calling it an AC traction motor is wrong because it is a DC traction motor.
Is there such a thing as a 3 phase DC traction motor though? And I also heard that railways nowadays are starting to use 3 phase AC induction motor for traction purpose.
@@wanfahim3583 Not really, but I think someone was referring to the driving circuitry that nowadays allows for driving 3-phase engines with 3-phase rotational current by generating it on the train. I'm not sure how common the method of doing it like that still is these days because the trains we have with that type of technique since the beginning of the 90's were so noisy (because the technology capable of doing what the trains required for the engine was new) that they got extra sound insulation measures installed after being put into service for the first time. Nowadays I think the type of engine circuitry is more based on pulse-length variation, but I could be wrong and it just sounds like that while it in fact isn't. In The Netherlands most of the trains run on 1500VDC.

IIRC, they don't..at least not in America. There's a shroud that covers those gears and they're well greased with GL. Running a set like that under actual load would give you about 10 minutes of proper operation before it turned itself into a welded mess. In fact, I'm sorta perplexed as to why they're running them bare at all.
Under normal circumstances, they're encased in a shroud, and below is a belly reservoir of oil whichs level is sufficiently touching the axle drivegear, providing the neccessary lubrication needed to prevent the gears running dry as seen in the video. That avoids the clanging sound heard, and dampens the gear whine and locomotive screaming through town.

Short term testing. The actual loco bogie will have the protective casing, gearbox with forced or bath type lubrication, and the blower fan to keep the motor cool, and there will be several more bogies with motors
Not required. The back wheels most of the time have less use of power, since the RPM contribution to the rear wheel is done by the front wheel. That is the reason the engine is at the front of the train and in every boggie you have small motor just to keep up with the rpm at high speeds. That's it
@@depression_plusplus6120 Some trains in The Netherlands have multiple engines of the same strength under each car (usually at each connection between cars, some trains have stopped using a wheelset on each end and instead share one with the joint resting on it). As for making sure there's an equal amount of rotation: electricity is a great thing, it won't produce more RPM than it requests, unless a wheel slips on the tracks. In the more modern trains sensors will typically try to prevent slipping by monitoring current draw (an engine at speed will consume less current) and a more or less expected type of speed increase, which, with something like slipping wheels provides a very characteristic deviation in rotational movement and current draw. Some systems will then automatically limit power to that wheelset or the train as a whole to prevent damage to tracks and wheels, and others will notify the driver who can use best judgement to reduce power or not.
Those are not AC tractor motors.... 4 wire is DC series wound motor, 2 for armature, 2 for rotor. If it was AC there'd be only 3 wires for the stator winding.
Maybe that was part of the test and it produced that sound purely because something is not right. But it can be anything, from a broken/worn out bearing to the gears running without their lubrication seal (and, practically dry as a result).
There was a proposal for running diesel locomotives on overhead power lines of electric locomotive.Will some one throw some light on progress of this project.
You can't just modify a Diesel Locomotive to run electric using existing Overhead Wires. You'd need to add a Transformer which is really heavy and takes up a lot of Space, plus all the other Electric Equipment but that is nowhere near as bulky as the Transformer. There are dual Power Locomotives but they have been designed like that all the Way back from the Factory.
Both actually, Diesel trains provide electric current to the motor from turning a generator using Diesel engine and electric train takes it directly from wires above.
Way more than 20kw. I don't know how much power specifically as I don't know what this is off, but if an EMU probably several hundred kilowatts, if off a locomotive - I'm guessing it is based on it's size - it could be several thousand kilowatts. I would assume it's air-cooled based on the screens next to the output shaft, possibly fans mounted on the shaft to blow or draw air through the rotor and stator windings.
@@mrb7931 Thanks for that info. What is this from, what locomotive? If it's a 1350 hp motor I could assume most likely the locomotive is either 5,400 hp if four axle or 8,100 hp if six-axle.
