We also sell the complete line of NetGain Motors, Inc. WarP,
ImPulse, and TransWarP DC series wound motors designed
specifically for EV's !  Check below for complete details and
pricing on each model motor. Any special requests, please
e-mail to us!
WarP 11 ™ Motor

It is a 11.45" diameter, series wound DC motor with a double ended shaft. Our
WarP 11 ™ motor  comes set with advanced timing CCWDE. Of the most notable
changes, we have a very large com and utilize the large style, very high quality
brushes.
The com bars are more securely attached to the arbor, so they will be less likely to
lift. The drive shaft is bored for a pilot bearing and drilled & tapped for a 5/16 - 18
bolt. The tail shaft also has a 1/4 - 20 bolt hole to mount tach sensors or secure
couplers and accessories. Again, we have duplicated the ADC 9" mounting bolt
pattern allowing clients to use preexisting mounting adapters. Class "H" insulation is
used throughout the motor. The drive shaft and tail shaft have standard keyways
cut into them.
ImPulse 9 ™ Motor

This is a 9.25" diameter, series wound DC motor with a double ended shaft and is
pre-drilled to allow for fixed brush timing advance in either the Neutral, CWDE or
CCWDE(default) position. Our ImPulse 9 ™ Motor shares many of the internal
components of our WarP 9 ™ Motor, but has the mounting pattern and pilot to
match 8" motors (Model 00-08259 & Model 00-08269). Model 00-08269 is the
single ended shaft version of this motor, and Model 00-08259 is the double-ended
shaft version.
The ImPulse 9 Motors have almost 30% greater brush area than 8" motors, larger
bearings, and more commutator area. The commutator bars are more securely
attached to the arbor, so they will be less likely to lift. The drive shaft is bored for a
pilot bearing and drilled & tapped for a 5/16 - 18 bolt. The tail shaft also has a 1/4 -
20 bolt hole to mount tach sensors or secure couplers and accessories. Again, we
have duplicated the ADC 8" mounting bolt pattern allowing clients to use
preexisting mounting adapters. Class "H" insulation is used throughout the motor.
The drive shaft and tail shaft have standard keyways cut into them.

TransWarP 9 ™ Motor

This motor has an 9.25" diameter. It is a series wound DC motor with a double ended
shaft. Our TransWarP 9 ™ motor has been designed to ease the conversion process
for people who want dual motor and/or direct drive applications. It has many unique
features that set it apart from any other EV motor currently manufactured.
fitted to the drive end-bell (may be ordered with or without housing!) This is because
the drive end shaft is not the typical 1.125" single-keyed type, but rather a hefty
1.370", 32-tooth involute spline that is identical to the tail shaft spline of a Turbo 400
transmission. In other words, this motor was designed to replace a transmission and
couple directly to a drive shaft!
We have added double wide bearings on the drive end, added grease fittings (as you
now have a slip-yoke assembly...). We use the industry standard 1350 universal, so
you can easily adapt it to any manufacturers drive shaft! The motor also has brush
wear indicators and a temperature snap switch. It has the same high efficiency fan
and massive commutator and brushes as the WarP 9 motor. We even made the
commutator end shaft the same diameter as the drive end of a typical WarP 9 - just in
case you wanted to connect 2, 9" motors together!
We also provide 2 lifting holes.
Motor does not include slip yoke or tailshaft housing--order below!
TransWarp11

This motor has an 11.45" diameter. It is a series wound DC motor with a double
ended shaft. Our TransWarP 11 ™ Motor has been designed to ease the conversion
process for people who want direct drive applications. It has many unique features
that set it apart from any other EV motor currently manufactured.
This motor has a "shorty" tail shaft housing from a Chevrolet Turbo 400 transmission
fitted to the drive end-bell (may be ordered with or without housing!) This is because
the drive end shaft is not the typical 1.125" single-keyed type, but rather a hefty
1.370", 32-tooth involute spline that is identical to the tail shaft spline of a Turbo 400
transmission. In other words, this motor was designed to replace a transmission and
couple directly to a drive shaft!
But we didn't stop there! We added double wide bearings on the drive end, added
grease fittings (as you now have a slip-yoke assembly...). We chose the industry
standard 1350 universal, so you can easily adapt it to any manufacturers drive shaft!
We moved the terminals to the side of the motor to avoid road hazard damage, and
to allow more clearance above and below. The motor also has brush wear indicators
and a temperature snap switch. It has the same high efficiency fan and massive
commutator and brushes as the WarP 11 motor. We even made the commutator end
shaft the same diameter as the drive end of a typical WarP 11 - just in case you
wanted to connect 2, 11" motors together!
If that wasn't enough, we also provide a lifting ring and 8 threaded mounting holes in
the commutator end bell. This way you will find it easier to mount, as well as having a
method of easily attaching a speed sensor, alternator, air conditioner, etc.
Motor does not include slip yoke or tailshaft housing--order below!
NetGain Supplied Slip Yokes  
NetGain uses only the finest 1350 slip-yokes for our patent pending EMIS technology
solutions. These slip yokes are manufactured by Spicer/DANA. They are 1350 series
universals, allowing for connection to almost any manufacturers driveshaft. We have
personally used these slip-yokes on vehicles that have produced almost 3,000 ft. lbs. of
torque. These slip-yokes are also the ones we recommend for use with our TransWarP
motors!
If you plan on using one of our exclusive TransWarP Motors, be sure to specify that you
also want one of these slip yokes! We cannot guarentee that other manufacturers slip
yokes will match the specifications of these slip yokes, so the use of other slip yokes
could damage your TransWarP Motor
NetGain tail shaft housing
The tail shaft housings that NetGain Motors, Inc. utilizes have been remanufactured to
better than original quality . These tail shaft housings have been extensively reworked to
fit the TransWarP ™Motors they are designed to match. TransWarP ™ Motors must
utilize a tail shaft housing, and we do not guarantee the use of any tail shaft housings
other than the ones we sell.

NEW ITEMS
Our WarP 9 ™ motor is similar to the ADC 9" motor, but with numerous improvements. It is a
9.25" diameter, series wound DC motor with a double ended shaft Of the most notable changes, we
have a larger com and utilize the large style brushes. Beginning with motors being manufactured in
July, 2010 numerous enhacements have been added to our entire line of motors, some of which
include: 1/2-13 diameter terminal studs: Increased from 3/8 diameter - bigger is better! New brush
composition: Handles higher voltages and currents improves motor efficiency New brush design:
split brush with pad design handles higher voltages and currents improves motor efficiency
Increased spring pressure: Spring pressure has been increased to allow improved commutation
(note: This does NOT increase brush-commutator wear as might be suspected)! Higher spring
pressures allow for increased commutation which improves commutator wear over bouncing
brushes. Addition of optical RPM sensor hole: A 1/2-20 hole is drilled and tapped into the DE for easy
insertion and use of an RPM sensor. (further information will be provided on appropriate sensors and
gauges (RPM, temperature) in the near future.) Addition of temperature thermistor: This will allow the
motor temperature to be be monitored.


. Improved fan: Increased air flow will allow the motors to run cooler and more efficiently. The 15-
blade fan is a new casting that will make using the RPM sensor easier as well. Drive End mounting
holes changed from blind holes to thru holes. If the wrong length bolts were used it could damage
the DE head. Care must still be exercised to ensure that the mounting bolts do not hit the fan blades!
Temperature snap switch and thermistor plug will use the same black plug that was previously used
for the brush wear indicators and accepts 1/4, flat spade connectors, but it will now be counterbored.
All of the above changes are being phased into production across ALL motors
The com bars are more securely attached to the arbor, so they will be less likely to lift. The drive shaft
is bored for a pilot bearing and drilled & tapped for a 5/16 - 18 bolt. The tail shaft also has a 1/4 - 20
bolt hole to mount tach sensors or secure couplers and accessories. Again, we have duplicated the
ADC 9" mounting bolt pattern allowing clients to use preexisting mounting adapters. Class "H"
insulation is used throughout the motor. The drive shaft and tail shaft have standard keyways cut into
them.
