Small DC Frame Sizes

  • 550, 775, 895 - etc frame sizes - [1]
  • Ex. 775 motor - 150W - [2]

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

  • $100/kW - [3]
  • 1kW is $150 - [4]

220 AC

Best price per kW for motors - $70/kW

  • 5 hp compressor motor - $180 - $60/kW - [5]
  • 5 hp/ 3kW compressor - continuous duty - $215 - [6]

Weird

  • 3hp AC - $30 - [7]
