## A Magnetostrictive Water Pump for Use in Extra-Vehicular Activity SatCon Technology Corporation, Cambridge, MA

**Innovation**
- Development of an extended-range magnetostrictive inchworm motor with a laminated terfenol-D moving element sandwiched between two double-layered three-phase stators.

**Accomplishments**
-  Achieved maximum speed of 12 mm/s, 150-N force capacity,and 25-mm travel
-    range.
-  Demonstrated precision motion control capacity or robotic applications with
-   closed-loop control.
-  Increased water pumps capabilities, while decreasing both mass and power needs.
-  Increased reliability through reduction in movable parts and component materials.
-  Received NASA contracts valued at over a million  dollars to further specialize
-    the pump for NASA purposes.
-  The firm has announced that it’s Semiconductor Products business unit will
-    introduce a new high speed, 5.7 gigahertz, RF Power Amplifier for Wireless
-    LAN applications at the Wireless Systems Design Conference and Expo
-    being held from February 26th to the 28th in San Jose, California.

**Commercialization**
- The firm has announced that Brown Simpson Partners I, Ltd. has exercised a warrant to purchase 675,000 shares of SatCon’s common stock. The aggregate gross proceeds to SatCon, as a result of the warrant exercise, were approximately $5.8 million. In connection with the warrant exercise, Brown Simpson received a new warrant to purchase 438,750 shares of SatCon’s common stock at an exercise price of $16.70 per share.
- Revenue for the fiscal 2001 third quarter rose 22% to $10.6 million, compared with $8.7 million in the same quarter last year.  Revenue for the nine months ended June 30, 2001 increased 52% to $31.7 million, compared with $20.8 million for the nine months ended June 30, 2000.
- On, February 21, 2002, SatCon Technology Corporation's announced that it’s Power Systems business Unit has received $1.5 million in orders for industrial automation and semiconductor equipment orders. The company views the orders as a signal that its industrial automation and semiconductor manufacturing equipment markets are beginning to turn around. The orders include approximately $1.0 million in MagLev systems, power supplies and servomotors for semiconductor equipment customers and approximately $550,000 for industrial automation components.
-  On January 22, 2002 , SatCon Technology Corporation's announced that it has
-        been awarded a $4.1 million contract from General Atomics to continue the
-        development of its Integrated Power System (IPS). The contract phase, when
-        added to the initial IPS phase, which began last February, brings the total value
-        of this program to $7.0 million. Under this phase of the contract, SatCon will
-        deliver 100kW and 300kW modular, electrical power converter and control
-        assemblies to be tested as part of a full-scale demonstration program for the
-        Navy’s "all-electric" ship.

**Government Applications**
-   The high-force and moderate-speed capability of the magnetostrictive motor
-     makes it well suited as a direct-drive replacement for geared down motors
-     for NASA robotic applications.
