Targets (500 cc methanol powered):
- Power: 40 kW (54 hp)
- Torque: 50 Nm (37 ft lbs)
- Weight: 80 kg (frame = 40 kg, motor + exhaust etc = ~40kg)
- Volume: ?
Actual (with 2 inch wide 2 magnet row motor, rated 6000 RPM, peak 10,000 RPM):
- Power: 50 kW (67 hp)
- Torque: 80 Nm
- Weight: 19 kg
- Volume: ?
Electrical Specs:
Controller:
- 330Vdc(nom) / 300Arms(3ph)
- liquid cooled (may not need active cooling for short bursts)
- 7.5kg
Battery:
- A123 cylindrical. 2.3Ah, 3.2V, 0.070kg, 70A 180Wcont - 2 minute run time.
- Option(1) 100cells (1p) - 320V, 18kWcont, 7kg (starter/junior pack) up to 30kW/10sec
- Option(2) 200cells (2p) - 320V, 36kWcont, 14kg (race pack) up to 60kW/10sec
Motor:
- 50kW over 5800-10000rpm
- 23 cm diameter, 16 cm long
- 19 kg
Power balance:
- 50kW mech
- Vdc 320V nom
- Idc - 180A
Weight
- Controller ~7kg
- Battery ~20kg, 150x150x750
- Motor ~19kg
- Total - should come out at around 45kg.
Summary:
- Due to Cell Voltage sag, peak available power will drop at higher motor RPMs.
- Motor slightly oversize
- Torque controller limited, power is battery limited
