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:
  • Weight:
  • 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

Advertised specs:

  • 50kW(66hp) 10,000rpm Electric Motor drive
  • 80Nm+ INSANE TORQUE!
  • 1500Wh 330V Battery (designed for 2min race runtime)
  • 15min Fast Charge
