0-5000 ohms, with microswitch
1000 Amps: The Soliton1 can deliver 1000A at all duty cycles at up to 300V (slight derating above 300V). If liquid cooling is used that is
a continuous current rating! Even with just the built-in fans/heatsink you can get 1000A for 15-20 seconds every 90-120!
300 Volts: The Soliton1 can operate on 10V minimum to 342V maximum.
600 Volt IGBT modules: Rugged design based on industrial IGBT modules, not lots of little IGBTs or MOSFETs in parallel.
Cutting Edge Input Capacitor: Ultra low loss polypropylene film capacitor. No electrolytics to overheat and fail!
High Efficiency: 1.5V max. drop at 1000A (0.8V typical).
Superior Electrical Layout: Internal laminated bus structure minimizes spikes and noise emissions.
CAD/CAM/CNC: Computer designed and CNC machined out of cast aluminum.
Rugged Enclosure: Anodized and silkscreened with epoxy ink for water resistance and durability.
Fan & Liquid Cooled Heatsink: Awesome heat-dissipation as-is; liquid cooling loops add even more.
Dedicated high power connections: Separate terminals (1/2") for the battery and motor connections. Makes for a clean and safe
Battery pack protection: both maximum current and minimum voltage on the battery side are programmable - protect your pack from
abuse while extracting the maximum performance and range from your pack.
Motor protection: motor voltage, current and total power can be limited; with separate limits for when in reverse.
Adjustable switching frequency: Losses in any controller go up with switching frequency; the Soliton1 lets you choose between higher
performance and efficiency (8kHz) or guaranteed silence at all current levels (14kHz).
Smooth starts: Dithering is used at low motor currents to maintain precise control and eliminate jerky starts without resorting to a huge
drop in switching frequency.
Idle: A world's first for EVs! Makes converting vehicles with automatic transmissions, power steering, A/C, etc. much easier!
Adjustable acceleration rate: The rate at which motor current is allowed to rise is adjustable from a tortoise-like 100A per second to a
tire-boiling 25,000A/s (functions essentially like traction control).
Built-in Main Contactor w/ Auto-Pre-Charge: Precharge management and main contactors are inside the controller.
Protected against wiring errors: All input terminals protected against reverse and over-voltage. All output terminals protected against
short-circuit and inductive kickback (diodes recommended across all coils anyway). Even the battery pack terminals are protected
against reverse polarity and overvoltage!
3-wire throttle input: Accepts a 0-5V signal from a pot, automotive TPS or Hall effect pedal, etc.. The range is calibrated and "off" can be
compensated for drift. Polarity can be inverted and a broken throttle wire detected.
Tachometer input/ouput: Compatible with industrial proximity sensors (1, 2, 4, 6 per turn) to protect against motor over-speed and
necessary for idle. Tach output drives a 4cyl or 6cyl tachometer gauge regardless of input pulses/turn.
Brake input: inhibits the throttle when active for additional safety
Three programmable inputs: Reverse and motor over-temp so far, with sport/econo mode and cell-level low voltage cutoff coming soon
Three programmable outputs: Meter drivers to display motor and battery amps, power, etc. Switching twin motors between
series/parallel (coming soon).
Error light output: for reporting errors to the driver via the existing "Check Engine" light or other 12V indicator.
Web browser interface: Access all settings and update the firmware with an ordinary web browser!
Data acquisition: Performance data is continuously streamed to the Ethernet port (UDP format) at 0.1s intervals. A basic logging
program is available and the data format is open source.
Firmware upgrades: new features can be added to the Soliton1 without removing it from the vehicle - just upload the encrypted
firmware through the web interface (or optional "speed updating" program) and reboot!
We are now selling the SOLITON 1 and SOLITON JR high
performance controllers by EVnetics llc- the controller is now no

NetGain Controls WarP-Drive Liquid Cooling Kit
WarP-Drive Hall-Effect Pedal Assembly
This Speed Sensor was designed in the USA specifically for the WarP series of motors with a tailshaft diameter of .875" and replaces the Zolox
Speed Sensor. However, the kit could fit any motor with an exposed tail shaft.
To install the sensor, slide the exciter ring over the tailshaft of the motor, then using the included stainless steel mounting plate, situate the sensor
shaft can also be used to power a compressor or other device requiring shaft input.
To install the sensor to a tachometer gauge, use the included adapter harness. Hook the wires on the adapter directly to the corresponding wires
on the tachometer, and then plug the adapter's connector into the sensor cable's.
WarP Motor Speed Sensor Kit
With over a half-megawatt of power output capability
and its professional quality, this silent powerhouse is the
new controller of choice! Designed with ruggedness in
mind, and ease of use, it is the perfect controller for
hobbyists and OEMs alike. The WarP-Drive has the
quality you would expect from a NetGain product, at a
price you can afford.
The base unit comes programmed for 1000A continuous
rated output at 160V, and is user-upgradeable to 1200
and 1400 amps and 260 and 360 volts. The WarP-Drive
comes from the factory with CANbus connectivity, which
gives it endless capabilities to operate in conjunction
with already-in-development third-party hardware
A single WarP-Drive unit can be configured to output up to 1400 amps. The
base unit starts out at 1000 amps with 200 amp upgrades available up to
The input and output current can be set to whatever limits you want using
the NetGain Controls Interface Module. This feature can be used to protect
your batteries, while providing you with the most power output possible.
Variable Current Input/Output
The unit can be initially purchased with 160, 260, or 360V nominal
limits. Customers can purchase upgrades at any time that allow the
end-user to perform the upgrade. This versatility allows customers to start
with a feature-packed controller, and scale to higher pack voltages as
The output voltage (motor voltage) can be configured using the NetGain
Controls Interface Module to limit the voltage that the motor sees. This is
especially useful for higher pack voltages used with motors that are
limited (such as the NetGain WarP, ImPulse, and TransWarP, which
have a limit of 160-170V).
Variable DC Voltage Input/Output
When you show off your new electric vehicle, you don't want the on-lookers thinking they are at a middle-school science fair! The WarP-Drive takes
several steps to provide factory quality, with a "show-off" flair! Waterproof automotive connectors and its water-resistant case make it suitable for
installation under the hood. The flame-proof polycarbonate cover reveals the internals, displaying what it takes to dish out all that power. Use of the
industry-standard communications protocol "CANbus" make it compatible with hardware of the future that hasn't even been developed yet.
The best controllers on the market use liquid cooling to wick away the heat produced. The WarP-Drive uses precision machined liquid chill plates.
Connecting to the chill plate is extremely easy! No fiddling with hose clamps - simply "plug" a 3/8" OD vinyl hose into the quick connections and
you're done! We also carry a custom cooling kit for the WarP-Drive. This kit can be installed in under an hour.
For a price of $1950, a base controller (160V, 1000A) can be purchased today. A few thousand miles later, when you're ready and can afford more
power, firmware upgrades can be purchased to allow more power or a larger battery pack.
Hall Effect Pedal Input
The WarP-Drive exclusively uses a Hall-effect throttle input (no 0-5K ohm "potboxes"!). NetGain Controls provides two types of throttle assemblies.
One is a complete pedal unit (HEPA). And for those who have used a pot-box in the past or those simply not wanting to change out the original
accelerator pedal, a unit is available that can connect to the existing throttle cable (HETA).
Safe, Durable Connections
Consumer safety was of utmost priority when designing the WarP-Drive. As such, the high voltage terminals on the controller were placed on top, with
generous distances separating them. When connecting terminals are outfitted with protective boots, this setup decreases the chance of a dropped
tool arcing across terminals. Connecting and disconnecting the main power cables is much safer, as a single hand can be used.
Throttle, precharging, and data output terminals on the controller's front are automotive quality, waterproof connectors. Although the controller
should be located away from frequent direct exposure to liquids, it can take splashings without any problems.
External Construction Optimized for Size, Weight, Function, and Durability
The WarP-Drive weighs in at just under 16.5lbs (7.5kg)! It is approximately 6 " high (to top of capscrews), 9" wide, and 10.75" long. All core
functionality is built into the single unit, eliminating the need to mount multiple enclosures.
The WarP-Drive's base plate and side plates are made of anodized aluminum. These plates are not only visually appealing, they also act as an extra
heat sink to wick away heat.
The clear plastic cover is made of the highest flammability rated polycarbonate (UL94V-0). Besides resisting burning, the cover also resists warping
due to sun exposure. At about 1/8" thick, the cover is almost impervious to shattering or denting.
Designed for any temperature situation, the WarP-Drive internally protects itself from overheating. When using the available cooling kits, temperatures
can usually be limited to below 55C. However, some situations can arise causing the temperatures to rise above this (e.g. a pump failure). At 55C,
maximum power output capability is decreased. At 80 Celsius, the controller begins to more aggressively reduce power output. At 100C, the
amp-output capability hits zero.
The Quality You'd Expect From NetGain
The WarP-Drive controller by NetGain Controls, Inc., has the quality you would expect from the NetGain name. The unit is built with the highest
quality components, and assembled in a professional electronics assembly facility.
