Motor design optimisation using SPEED CAD software

SPEED (Scottish Power Electronics and Electric Drives) is a consortium of industrial companies with a common interest in power electronics and motor drive technology. SPEED was formed in 1987 in the Department of Electronics and Electrical Engineering at the University of Glasgow. The SPEED Laboratory produces electric motor design software which is used by the membership of over 55 companies from Britain, Europe, the USA, S. America and Japan. SPEED software is available for induction motors (polyphase/1-phase); brushless permanent-magnet motors (square wave/sine wave); DC brush motors; switched reluctance motors; and synchronous reluctance motors. It runs on the IBM PC platform, is easy to learn and use, with full documentation that includes extensive information on motor theory and design. This paper describes the software structure, analysis options and operation using the PC-BDC program for a brushless PM motors as an example. A link from PC-BDC to a finite element program is also described.
