3-Phase AC Induction Motors and Horsepower
by Jason Conroy
My 3-Phase AC Induction Motor Has How Many Horses?
You mention that the 3-Phase AC induction motor is probably the best choice, and I would like to know more.
Where can you purchase one?
How much do they cost?
What is their weight?
How much horsepower do they have?
Hi, Jason -
Two places to buy these motors: Metric Mind and Electro Automotive, both in the US.
Take advantage of our weak dollar, will you?; )
Cost: The prices will vary, so check the websites for current prices.
Weight: 85 lbs. for a motor that will move a Porsche 914 along at a brisk clip; 235 lbs. for a motor that will push the SUV.
Horsepower: Forget horsepower, think kilowatts instead. That 3-phase AC induction motor that will move a Porsche 914 along at 100 mph has a rating of 43 kw peak, 14 kw continuous.
2011 Update: There's a new AC electric vehicle motor on the market now that will drive your Porsche at 100 mph for about $4600 for the motor/controller combination.
