TeraTorq® High Performance Motors and Generators
 Designed for long life use in harsh environments –
rugged, sealed, and highly shock tolerant
 Patented, propriety designs provide as much as 5X
reductions in size and weight compared to motors
and generators from other vendors
 Low rotor inertia enables unmatched, precise control
 High efficiency
 Customizations for your system may include -
mounting, shaft interface, housing material,
pressure compensation, and cable entries
 TeraTorq ® motors can be powered and controlled
by third party drives via SSI or RS485, or a custom
interface, but in a few slides you can read about
our TIM-270 modules, which have many
advantages over other drive solutions
TeraTorq® motors have been deployed in subsea applications for military use since 2003, and on drill rigs since 2004. TeraTorq® motors and
generators have logged millions of hours of rugged field use.

9. Variable Speed Generator (VSG) Operation
 Eliminate need for synchronization
equipment and processes
 System power can be independently
regulated from multiple generators
running at different speeds and
voltages
 Boost rectifiers convert output to
regulated DC for drive lineup, so
frequency doesn’t matter
 Built-in fault protection
 Reduce engine wear and maintenance
 Reduce size and weight
 Reduce fuel consumption and
emissions

10. The Most Advanced Modular Drive System
The image on the right
features multiple racks of
TIM-270s, or TIMs
(TeraTorq® Inverter
Modules).
Page 10Comprehensive Power Proprietary

11. TIMs
 200kW / 250Hp power, 9”x9”x25” modules,
typically deployed in arrays
 TIM-270 modules are fully interchangeable with
each other, reducing the number of spare parts
needed to stock. Any TIM can automatically
perform:
 AC/DC Rectification
 DC/AC Inversion
 DC/DC Power Balancing
 TIMs are used to:
 Drive motors
 Transfer power from a generator or other
source
 Transfer power to/from a switchboard or a
battery bank
Page 11Comprehensive Power Proprietary

12. Theory of Operation - TIMs
 Each module has 6 power terminals
 DC plus, minus and ground
 3 AC (input / output) phases
 Connected to DC by IGBT switches
 Current can flow in any direction based on switch control
 IGBTs switch rapidly with Pulse Width Modulation (PWM) control
 Output is smoothed by phase inductors
 Harmonics are actively controlled and reduced
 AC voltage is between DC plus and minus
 AC phases provide or draw current on command, at any
frequency from DC to 1,000 Hz
 Modules automatically balance loads when connected in parallel
 Can draw power from lower AC voltages with active power factor
correction

13. Motor Terminal Voltage with TIMs
 Phase inductors in
each TIM locally
filter and contain
the high frequency
 Eliminates many of
the problems seen
with inverter
driven motors
 Eliminates the
need for special
cables and
shielding

14. TIMs
 Designed for continuous “always on” redundant, fail-
safe system operation
 The unlikely event of a failure of a TIM-270 in a
multiple TIM system only decreases the system power
proportionately
 Such a failure will still yield continued system operation
and avoid emergency equipment shutdown
 TIM-270 modules can safely and easily be swapped or
replaced by anyone; no factory certification or special
training is required. Replacing a TIM-270 is a simple
“plug and play” operation.

15. TFMs (TeraTorq® Frame Modules)
 Modular, expandable drive mounting system
 Power
 Liquid cooling
 Control
 TFMs hold up to 4 TIMs
 About 49” tall, 30.5” deep, 10” wide
 All module connections are blind mate quick
disconnect for safe and foolproof operation
Page 15Comprehensive Power Proprietary

16. TCM (TeraTorq® Control Module)
 Controls the operation of TIM lineups,
which may be connected to motors,
generators, renewable energy sources,
batteries, ultracaps, switchboards, etc
 Provides information to/from a system
controller via the Modbus Application
Protocol (MBAP) over an Ethernet
TCP/IP connection
 Support for web based data collection,
troubleshooting, and preventative
maintenance programs

18. FAQs
 Can I use TIM drive lineups with motors or generators
that are not manufactured by Comprehensive Power?
 Yes you can (although we would like you to consider all
of our equipment, including our motors and generators,
our drives are compatible with products from other
manufacturers).
 Can a TIM really be replaced by non-factory personnel?
 Yes. After following your defined safe lockout procedure
for the drive line, just push a button and pull the handle
to remove, and then slide a replacement in.
 Can I use my own housing for my TIMs, TFMs, and TCMs?
 Yes. we will assist your design efforts and support the
deployment of the equipment within your own housing.
 Also we sell rack systems and cabinets, and we can
recommend partners who also sell racks and cabinets for
our power electronics.
Page 18Comprehensive Power Proprietary

19. FAQs (con’d)
 If a TIM fails, does my system stop operating?
 No. In the unlikely event of a TIM failure, the
remaining TIMs will continue to operate, and the drive
lineup will have proportional power available.
 Does a TIM need to be programmed or require a hardware
modification to perform an AC/DC conversion or another
function?
 No. Any TIM can perform any function, and any TIM
can be placed in any TFM slot. The TIM’s function is
controlled by a TCM which is part of the drive lineup.
 Can this drive and power electronics system function as a
Microgrid?
 Yes. TIM systems support power being supplied from
one or multiple sources, including transformers,
switchboards, grid connections, generators and battery
banks. Power can be distributed to multiple loads,
including hotel loads, MCCs, motors and battery banks.
