MotorLeroy Somer 4KW old model, 4 poles, aluminium, 30 KG 3-Phase AC
We bought this ancient motor in a junkyard and rewound it to
48VAC. It works like a champ! Got about 20HP peak power, but we
think it could provide much more with higher voltage.
DrivetrainChain transmission, direct. 11:45 ratio
ControllerCurtis 1236
Batteries24 Sinopoly 60Ah, 0.00 Volt, Lithium Iron Phosphate
About 40 KG of LiFePo
System Voltage72 Volts
Charger Unknown Chinese 600W charger plus BMS (external)
We built the BMS externally, using a plug, in order to avoid it
charge/discharge limits.
DC/DC Converter Unknown, Chinese. Two fo them, 10A each
Top Speed37 MPH (59 KPH)
It has no gears and voltage is low; torque ends abruptly at 2100
rpm (aprox).
Acceleration0-20 mph: 2 seconds
0-30 mph: 7 seconds
Range20 Miles (32 Kilometers)
Not really sure; maybe 20 miles of forest paths. About 1-2 hours,
depending on driving.
Seating Capacity2 adults
Curb Weight480 Pounds (218 Kilograms)
We tried to keep close to the original weight (420 lbs).
Conversion TimeAbout 1 year and a half. Tried different components along the
Conversion CostProbably around $4000, mostly battery+controller
Electric Mojave rules!
