NEMA Motor Sizes
- See NEMA
Basic
- This page explores sourcing for various electric motors
- Summary: 4 hp treadmill motors (high voltage DC) are the cheapest replicable source of motors per horsepower - at $20 per horsepower. Next is 5 hp compressor motors for $180, or $60/kW. Interesting, the surplus treadmill motors are a win. Since they are 130VDC, you could rectify regular wall power or use batteries
BLDC Hub Motors
220 AC
Best price per kW for motors - $70/kW
Weird
- 3hp AC - $30 - [6]
