Small DC Frame Sizes
No Gearbox
- 550, 775, 895 - etc frame sizes - [1]
- Ex. 775 motor - 150W - [2]
- Ex 895 motor - 360W - $17 - 12000 RPM - [3]
Geared
Using Existing Drills
- Corded drills may be used as a power source.
NEMA Motor Sizes
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 - [8]
