Motors

• TSINY TRS-775W - spec sheet [1] - study spec sheet for peak vs stall power
  • At max efficiency, TRS-775W has 135 mN-m torque = 0.14 N-m torque = 0.014 kg-m force.
  • 220W output power, 17A at 17V for max efficiency. 2.4 no load.
  • 12V no load 1.4A. Take 1.4/2.4 * 17A = 10A - or 120W at 12V. Just about right.
  • .75*120=90W. That is about right - for
• RSRS-550s 18v - [2]
  • 150W-180W energy use (not output power)
• Jameco - 0.6 kg cm torque at max eff - $5 -
• Jameco - 0.6 kg cm torque 78% max eff - $3 - [3]
