Electric Vehicle Conversion Kit for VW Frame
Conversion Kit VW Bug Frame
This is an electric vehicle conversion kit with the essential
parts needed to make your car run on electricity. This kit can be installed in
one day if you have a little mechanical experience. It is designed to work on a
VW bug standard transmission, and will work with any air cooled VW based frame
or kit car from 1952 to 1979. Automatic VWs are not recommended with use of this
kit. This kit is designed to be clutchless with the VW, but you still do shift
by just letting off of the throttle pedal when shifting. After installed, the VW will get top speeds of 45-55 MPH once the batteries
and motor are worn in and will get a range of 15-40 miles according to driving
habits, etc. Average range would be 25 to 30 miles on a charge once everything
is worn in, but this all depends on what batteries you use and how many, etc.
The parts included in this auction are: (#1) Permanent Magnet DC motor measuring
8 in diameter x 7.42 inches long. (#2) An adaptor
plate that matches the VW standard transmission to the series motor. (#3) A splined shaft coupler that couples the electric motor the transmission output
shaft. (#4) A motor controller by Alltrax model # 7245 (72 volts 450 amps) (#5 )
A throttle box that attaches to the gas pedal throttle cable. (0-5k PB-5)
#1 Permanent Magnet DC Motor
The ME1003 has a double brush set to handle 200 amps continuous. This ME1003
is a Brush-Type, Permanent Magnet DC motor with very high efficiency. For
voltages from 12 to 72 VDC input and 200 amps continuous (500 amps for 1 minute)
@ 72 Volts. It is rated at fifteen Horse-Power continuous and thirty HP Peak at
72 VDC. Electric cars are driven by large electric motors usually rated between
3.5 and 28 horsepower. For those accustomed to gas engines, this may not seem
like much power, but the rating systems used for gas engines and electric motors
are so different that the numbering system is almost meaningless. Gas engines
are rated at their peak hp, electric motors are rated at their continuous hp.
The peak hp of an electric motor is usually 8 to 10 times its continuous rating.
A 30 hp electric motor will generally perform like a 50-75 hp gasoline engine in
a same weight vehicle. This kit has no clutch so it can simply be driven just
like an automatic transmission.
Power 11.5KW continuous,
23KW Peak for 1 minute @ 72Volts
Voltage 12-72 Volts
Speed 3050 rpm at 72V Unloaded
Size 8" OD, 7.42" long (w/o shaft)
Shaft 7/8"x 1-5/8", 3/16" key
Weight 36 Lb.
#2 Adaptor Plate
The adaptor plate is bolted to the electric motor with four
1" x 3/8 " bolts. It matches the bell housing of the VW standard transmission.
It’s made from mig welding 1/4" steel plate.
shaft coupler is what slides onto the electric motor which uses your clutch disc
from your VW. Your clutch disc, which is your splined piece, is bolted to this
coupler with 8 hardened allen screws provided. This is what then slides onto
your transmission shaft of your VW. Depending on whether you rivet holes are
large enough on your clutch disc (different brands) will determine if you have
to drill them bigger or not for attaching it to your shaft coupler. When the
motor, adaptor plate and coupler are assembled together, the unit can then be
slid onto the transmission, with four bolts to the transmission housing, and the
mechanical work is finished. This part can literally be done in a few minutes.
There is a 3/16 keyway that is 2 ½" long with a 1/4" allen set screw on the
coupler. These couplers are machined in a lathe made with industrial grade
Included in this kit is a state-of-the-art PWM (pulse width
modulation) MOSFET (metal oxide semiconductor field effect transistor). These
model # SPM-72400, are made by Alltrax and are fully
programmable. You can even monitor the motor parameters while driving using a
laptop computer. For more information and software see their website.
#5 Throttle Box
Also included in this kit is the 0-5k ohm throttle box that
is design to work with the Alltrax controller. This is PB-5 type and will need
to be mounted
in the engine compartment and connected to the foot pedal throttle cable.
General assembly instructions and wiring
diagrams for this kit is included with this auction. We have built many electric cars, so any or all questions are welcomed.
