MotorNelco N200ML012 Separately Excited DC
Monster 385lb Sepex motor (with interpoles) and both internal and
external forced air cooling. I've never seen the motor get warm enough
for the external fan to kick on. Power rated at 80+HP (60kw) and 238 ft.
lbs. (Nm) torque continuous. Peak power unknown, but I'm sure quite
DrivetrainG-Van drive train, Sep EX Nelco motor and a Chloride Controller, Phil
S. Described it nicly for his G-Van:
The rear axle is "flipped" so the drive spline faces aft and where the
fuel tank normally would live, there is a stubby little drive shaft that
feeds into a custom-built transfer case. The electric motor is mounted
longitudinally on the passenger side and connected into the transfer
case. The whole assembly is mounted on rubber mounts to a subframe
that bolts up into the van. The drive ratio of the transfer case is 1.85:1
and the axle is 4.875:1. In the transfer case, They have an electronic
speed pick up and a parking pawl lock system just like an automatic.
It's nicely built, but can "whine" a lot during regen. (much like the way a
standard transmission does in reverse)
ControllerChloride Mark 5-A
A nice description again from Phil S.:
High Frequency PWM based on a single massive 500A Darlington
power block and a smaller (300A) one for Regen. There is also a
smaller 4-quadrant PWM drive circuit for the SepEx field. Two 600 amp
contactors break both positive AND negative pack voltage. All control
circuits are optically isolated from everything else. Completing the unit
is a 40A @ 14v DC-DC converter. Built on a massive cast heat-sink
with a fiberglass top cover
Batteries36 Saft STM 180, 6.00 Volt, Nickel-Cadmium, Flooded
System Voltage216 Volts
ChargerManzanita Micro PFC 20
HeaterDiesel fueled hot water
DC/DC ConverterBelktronix 60 amp
This is in addition to the 40 amp DC to DC in the chloride controller
InstrumentationLink 10 and custom panel and gauges
Top Speed60 MPH (96 KPH)
AccelerationBest described as "stately", Hey, it weighs over 7000 lbs, but it keeps
up with traffic nicely, plus it is more aerodynamic than my G-Van
Range60 Miles (96 Kilometers)

often refered to as a 22 foot long black hole to pour money into :-)
Additional FeaturesWith vacuum brakes and MR2 electric power steering, instead of the old G-vans continuous hydrolic
pump, requiring a continuous 5 amp draw, overall effcincy has inproved. Air conditioning uses a 3
phase compressor driven with an inverter from the pack consuming up to 6 amps. Due to the sepex
DC motor regen is excellent, up to 150 amps!
Just turned 6020 EVmiles! with new paint. many more small details to work out.
Many thanks to John Jessie for his skillfull metal fab, welding, fabrication and powder coating of the
battery racks and other assemblies so motor and batteries could installed under the deck. Without
Johns help this project would not have been possible, If you need similar high quality work he can be
reached at:jjj(at)775.net

To begain this project I was fortunate to acquire a second G-Van with a beat up body, but good
running gear as a parts donor. The '73 Hearse came from Santa Rosa Ca. with 9500 original miles,
engine trouble, and some rust from salty air. Now painting is all done ,front carpet and music installed. I
am in process of replacing the rear deck inside as to be faithful to the original and still provide easy
access to batteries and motor. More Photos coming asap.
