Camosun College Mechanical/Electronics Engineering Technology project.
MotorBaldor 3-Phase AC
Originally 10HP/230VAC rewound to 30VAC
Drivetrain10HP 3 phase AC rewound to 30VAC. Chain final drive.
Nominal 48VDC to 30VAC inverter. Stellaris Luminary LM3S9B96 microcontroller, Intersil HIP4086 3 phase driver chip and 24 100V/180A MOSFET transistors on a custom aluminum heatsink.
Batteries4 Optima SC31DM, 12.00 Volt, Lead-Acid, AGM
Thanks to Interstate Batteries in Victoria BC for their awesome support.
System Voltage48 Volts
Batteries are currently charged individually. Custom charger is next year's project...
HeaterThe Sun.
InstrumentationMechanical speedometer driven by front wheel. RS-232 output from CPU to future data-logger and onboard LCD realtime display.
Top Speed55 MPH (88 KPH)
TBD. 60Hz should make about 90kmh on level highway.
Range30 Miles (48 Kilometers)
Well, hopefully 30 miles. I guess we'll see...
Seating Capacity2 adults
Conversion TimeOne quarter (three months) for mechanical conversion and proof of concept (complete). Freshly rewound low voltage motor is installed and Electronics Technology students are developing new inverter software for a new realtime processor and new snubber circuitry.
Conversion CostOriginal bike $2500 but I rode it for a couple of years. dsPIC development system with IDC2 programmer $700. Motor & rewind $1400. Batteries, cables, switches, relays, breakers, drive chain & sprocket, various electronics like FETs, optocouplers, DCDC converters and drivers, etc... about $3000. New stuff the students will want ??? I really don't want to add that up.
This was a Camosun College design project completed by four Mechanical Engineering Technology students during one quarter (three months) in 2008. See our live TV interview (60MB) at: WebPage

The original design used transformers to drive a 460VAC motor but losses were FAR too high... A 230V/10HP motor has been rewound for 30VAC and is now installed in the bike.

Two Camosun College Electronics Technology students are completing the electronics design and implementation and I'm currently looking at a charger/battery management system. We're hoping to drive it around the College parking lot early this Summer (2010).
