               This Statement on Schedule 13D relates to shares of Common Stock,
$0.01 par value per share (the "Shares"),  of American Superconductor Corp. (the
"Issuer").  This  Statement is being filed by the Reporting  Persons (as defined
below) to report the transfer of the investment  advisory contract between Soros
Fund Management  ("SFM") and Quantum Fund N.V., a Netherlands  Antilles  company
("Quantum Fund"),  whose principal operating subsidiary is Quantum Partners LDC,
a  Cayman  Islands  exempted  limited  duration  company  ("Quantum  Partners"),
pursuant  to  which  SFM  was  granted  investment   discretion  over  portfolio
investments, including the Shares, held for the account of Quantum Partners. The
investment  advisory  contract  has been  transferred  from  SFM to  Soros  Fund
Management LLC ("SFM LLC"), a newly formed Delaware limited  liability  company.
As a result of this transfer,  certain of the Reporting Persons may be deemed to
be the beneficial owners of more than 5% of the outstanding Shares.

Item 1.        Security and Issuer.

               This  Schedule  13D  relates to the  Shares.  The  address of the
principal executive offices of the Issuer is Two Technology Drive,  Westborough,
Massachusetts 01581.

Item 2.        Identity and Background.

               This  statement is being filed by SFM LLC, Mr. George Soros ("Mr.
Soros"), Mr. Stanley F. Druckenmiller ("Mr. Druckenmiller") and Duquesne Capital
Management L.L.C., a Pennsylvania limited liability company ("Duquesne LLC," and
together  with  SFM  LLC,  Mr.  Soros  and  Mr.  Druckenmiller,  the  "Reporting
Persons").  This  statement  relates to Shares held for the  accounts of Quantum
Partners and the Duquesne LLC Clients (as defined herein).

               Effective as of January 1, 1997,  SFM, a sole  proprietorship  of
which Mr. Soros is the sole  proprietor,  transferred  its  investment  advisory
contract with Quantum Fund to SFM LLC as part of a restructuring of the business
of SFM,  which will now be conducted  through SFM LLC. SFM LLC has its principal
office at 888  Seventh  Avenue,  33rd  Floor,  New  York,  New York  10106.  Its
principal  business  is  to  serve,  pursuant  to  contract,  as  the  principal
investment manager to several foreign investment  companies (the "SFM Clients"),
including  Quantum Fund and Quantum  Partners.  Each of Quantum Fund and Quantum
Partners has its  principal  office at Kaya  Flamboyan 9,  Willemstad,  Curacao,
Netherlands  Antilles.  SFM LLC's contracts with SFM Clients  generally  provide
that SFM LLC is  responsible  for  designing and  implementing  the SFM Clients'
overall  investment  strategies;  for  conducting  direct  portfolio  management
strategies  to the extent  that SFM LLC  determines  that it is  appropriate  to
utilize its own portfolio management capabilities; for selecting, evaluating and
monitoring other investment advisors who manage separate portfolios on behalf of
SFM Clients;  and for allocating and  reallocating the SFM Clients' assets among
the outside managers and itself.

               The business of SFM LLC is managed through a Management Committee
(the "Management  Committee")  comprised of Mr. Soros, Mr. Druckenmiller and Mr.
Gary Gladstein. Mr. Soros, as Chairman of SFM LLC, has the ability to direct the
investment  decisions  of SFM LLC and as such may be deemed  to have  investment
discretion  over the  securities  held for the accounts of the SFM Clients.  Mr.
Druckenmiller,  as Lead Portfolio  Manager of SFM LLC, has the ability to direct
the investment decisions of SFM LLC and as such may be deemed to have investment
discretion  over the  securities  held for the accounts of the SFM Clients.  Set
forth in Annex A hereto and incorporated by reference in response to this Item 2
and  elsewhere  in this  Schedule  13D as  applicable  is a list of the Managing
Directors of SFM LLC.

               The principal  occupation of Mr. Soros, a United States  citizen,
is his  direction  of the  activities  of SFM LLC,  which is carried  out in his
capacity as Chairman of SFM LLC at SFM LLC's principal office.

               The principal  occupation of Mr.  Druckenmiller,  a United States
citizen,  is  his  position  as  Lead  Portfolio  Manager  and a  member  of the
Management  Committee  of SFM LLC,  which is carried out at SFM LLC's  principal
office. Mr.  Druckenmiller also owns a 75% interest in, and is the sole managing
member of,  Duquesne  LLC, an  investment  advisory  firm.  Duquesne LLC has its
principal offices at 2579 Washington Road, Suite 322,  Pittsburgh,  Pennsylvania
15241-2591.  Its  principal  business is to serve,  pursuant to  contract,  as a
discretionary  investment  advisor to a limited number of institutional  clients
(the "Duquesne LLC Clients").

               Pursuant to  regulations  promulgated  under Section 13(d) of the
Act,  SFM LLC,  Mr.  Soros,  in his  capacity as  Chairman  of SFM LLC,  and Mr.
Druckenmiller, in his capacity as Lead Portfolio Manager of SFM LLC, each may be
deemed a beneficial  owner of  securities,  including  the Shares,  held for the
account of Quantum Partners as a result of the contractual  authority of SFM LLC
to exercise voting and dispositive power with respect to such securities.

               Pursuant to  regulations  promulgated  under Section 13(d) of the
Act, each of Duquesne LLC and Mr.  Druckenmiller,  by virtue of his interest in,
and  position  as sole  managing  member  of,  Duquesne  LLC,  may be  deemed  a
beneficial owner of securities,  including the Shares,  held for the accounts of
the  Duquesne LLC Clients as a result of the  contractual  authority of Duquesne
LLC to exercise voting and dispositive power with respect to such securities.

               During  the  past  five  years,  none of the  Reporting  Persons,
Quantum Partners and, to the best of the Reporting Persons' knowledge, any other
person  identified  in  response  to this  Item 2 has  been (a)  convicted  in a
criminal proceeding, or (b) a party to any civil proceeding as a result of which
he has been  subject  to a  judgment,  decree or final  order  enjoining  future

state securities laws, or finding any violation with respect to such laws.

               The Shares held for the accounts of Quantum  Partners,  other SFM
Clients  and/or the  Duquesne LLC Clients may be held  through  margin  accounts
maintained with brokers, which extend margin credit as and when required to open
or carry positions in its margin accounts,  subject to applicable federal margin
regulations, stock exchange rules and such firm's credit policies. The positions
which may be held in the margin accounts,  including the Shares,  are pledged as
collateral  security  for the  repayment  of debit  balances  in the  respective
accounts.

               All of the Shares  reported herein as having been acquired for or
disposed of from the accounts of Quantum  Partners  were acquired or disposed of

the best of their knowledge, any of the other individuals identified in response
