Not the same as the motors in electric cars but impressive anyway. 200 horsepower 480 volt 3 phase electric motor. Height 5 ft weight estimate 1000 lbs. This is a very efficient motor that is speed controlled by a vfd. Produces 100 percent available torque at zero rpm. This monster fills a 20" water pipe. What are they using in the new electric cars?Electric motor vs. Gas engine

Re: Electric motor vs. Gas engine
About 10% of all power generated in the US goes towards pumping water. You should've seen the monsters I've dealt with at power plants and water treatment facilities. They feed 6' diameter pipes.
LOL, according to the post count I'm an "expert." The only thing I'm an expert at is asking questions.
Re: Electric motor vs. Gas engine
No porting to do.
We had some big uns in the paper mill I worked at too.
Couple thousand HP DC drive to pump up to 43000 gal./min.
5000 HP on vacuum pumps, dimmed the lights a bit when you hit the start button on those.

I am sure they dimmed the lights in the whole area!

Re: Electric motor vs. Gas engine
I had a career as a construction election and worked in all sorts of plants and factories... When a 400 HP motor starts the inrush of current makes the wires in the conduits stand up... but....To be in the generator room of a huge hospital during the test run of four Cat Diesel V12 engine powered generators....the engine run up against the governor and then the load is transferred , the engines bog just a touch before taking on the load with full rated HP... At an air show seeing the start up of 2000 plus cubic inch radial engines.....Dressed in animals hides clinging to a naked frame motorcycle propelled by fire at high speeds....The intense idle of a fine tuned V8.....Internal combustion is sight sound and feel...And unrefined in a world of molded plastic....

Re: Electric motor vs. Gas engine
I got to see these years ago before they were shut down.
Northwest Steel and Wire, Sterling, IL.
"By 1968 NWSW installed a massive 250 ton furnace but it was during the 1970s that the scale of the furnaces at the Sterling plant became truly enormous. In 1971 and 1976 two 400 ton Electro-Melt furnaces were put in place, by George F Reitzel Electric. Those were the largest furnaces in the world at the time. A third furnace was converted to 400 ton capacity in 1979. In the same year NWSW employed 4,678 people, the highest number it ever employed as Whiteside County's largest industry."
I was told that when these kicked in, the north part of IL dimmed!!

I have run gen tests for a hospital and those things scream.

Re: Electric motor vs. Gas engine
They claim this system added 400 lb. ft. of torque to your existing engine. The electric motor installs between the transmission an rear axle (using a shorter drive shaft) and can be used as a stand alone electric system or in conjunction with the vehicles engine.

Re: Electric motor vs. Gas engine
The electric motors in electric cars aren't quite that big (LOL), they're typically liquid-cooled because of the power density, and they spin faster.
Anyone who has not had a ride in a Tesla Model S - preferably a P85D or P90D, the high performance all wheel drive version ... you owe it to yourself to give one a go. They are most impressive.

Re: Electric motor vs. Gas engine
Here is a cross section of our MAN B&W 12S90ME-C Mark 9.2 engine type.
The 12 cylinder two-stroke diesel engine is rated at 105,720 hp @ 84 rpm and powers this 19,000 TEU container ship which is currently the largest in the world:

Re: Electric motor vs. Gas engine
Just for fun I'll weigh in. When I worked at NASA Ames in the early 60s the Unitary Wind Tunnel had 180,000 hp worth of electric motors driving the compressor to just under sonic speed at the tips of the compressor section blades. It was later upgraded to 240,000 hp.
It took coordination with the electric utility to be able to run the beast. The original 40x80 tunnel that begat the larger test section tunnel mentioned above is a wimp power wise, it always was. Big though...
