General
- Use 5hp compressor motor, 220AC - see Electric Motors, 3450 running RPM
- Calculations - from Hydraulic Calculations- have hp to drive a pump = PSI*GPM/1714 => GPM=hp*1714/PSI=5*1714/3000=2.86 gal
- In order to not burn out motor - overload protection on motor? Yes, compressor motors typically have it.
- Pump to get - [1] but cw or ccw? Motor is CCW, so pump must be CW.
18650 Case
- Take a form factor comparable to common power tool batteries, say at 20V - 6 AH - $22 [2].
- For 10kW for 6 minutes - need 1 kWhr. 4 AH at 20v gives 80W for 1hr (year right).
- Realistic for good cells: 8 WH for 1 cell [3] at 2C discharge.
