7. TeraTorq® High Performance Motors and Generators
 Designed for long life use on drilling rigs and other
harsh environments – rugged, sealed, and highly
shock tolerant
 Optional hollow shaft facilitates compact coaxial
deployment
 Propriety design provides as much as 5X reductions
in size and weight compared to Motors and drives
from other vendors
 Low rotor inertia enables unmatched precision
 High efficiency with direct liquid cooling, eliminating
the need for a dedicated heat exchanger and blower
 Scalable platform design with dozens of sizes up to
20,000 Hp / 214,400 ft-lb
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 more than 4,000,000 hours of rugged field use.

8. TIMs
 200 kW / 250 Hp power conversion and control “building
blocks”, typically deployed in arrays
 TIM-270 modules are fully interchangeable with each other,
reducing the number of spare parts you need to stock. Any
TIM can be 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 8
Comprehensive Power Proprietary 02/27/2013

9. TIMs
 Designed for durability and for continuous, “always
on”, fail-safe 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.

10. TFMs (TeraTorq® Frame Modules)
 TFMs hold up to 4 TIMs
 All module connections are blind mate quick
disconnect for safe and foolproof operation and
maintenance
Page 10
Comprehensive Power Proprietary 02/27/2013

11. TCM (TeraTorq® Control Module)
 Controls the operation of TIMs, which are
connected to motors, generators, 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

25. 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, you are not required to do so).
 Can a TIM really be replaced by non-factory personnel?
 Yes. After following a safe lockout procedure for the
drive line, push the red button and pull the handle to
remove.
 Can I use my own housing for my TIMs, TFMs, and TCMs?
 Yes. We do sell rack systems and cabinets, but we
will assist your design efforts and support the
deployment of the equipment within your own
housing.
Page 25
Comprehensive Power Proprietary 02/27/2013

26. 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 control system function as a Microgrid?
 Yes. TIM systems support power being supplied from
one or multiple sources, including transformers,
generators and battery banks. Power can be
distributed to multiple loads, including hotel loads,
MCCs, motors and battery banks.
