SPEED is a specialized analysis tool for the design of electric machines such as motors, generators and alternators including the drive with inverters and their control. Backed by 25 years of experience within the SPEED Lab at the University of Glasgow, SPEED has 1500+ international users, including leading manufacturers, designers, developers and users of electric machines. Thousands of machines have been designed with SPEED, and millions have been produced. SPEED is a simple, intuitive, fast and efficient tool for: • Sizing and preliminary design of new prototypes. • Characterization of new & existing products: performance study and quick assessment of the effect of parameter changes. Furthermore, its highly organized data in both numerical and graphical form facilitates communication between company sites, and often between supplier and customer. Finally, SPEED can be used in conjunction with high-powered specialist CAE tools such as STAR-CCM+ for the exhaustive analysis of difficult electromagnetic, mechanical, or thermal problems. SPEED’s ability to run the EM field solver in an embedded mode combines comprehensive analytical models covering all aspects of the design of these machines, including thermal, electromagnetic and drive control. Enhancements have been made in all aspects of the design calculations to improve accuracy and cover an even wider range of machine geometries. Of particular importance is the efficient utilization, and even elimination, of magnets. The SPEED suite of programs is now structured to give seamless design capability over the entire range of permanent-magnet machines and the alternatives including hybrid combinations. SPEED covers the entire range of power, voltage, and speed used in vehicle systems. SPEED plays a key role not only in drivetrain engineering but also in auxiliaries such as starter generators, many kinds of pumps, blowers, actuators, and even the KERS systems used in F1.
