A world-leading Design Program

 

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.

 


Industry Highlights of SPEED's New Features

  • Aerospace
  • Automotive
  • Industrial
  • Refrigeration

High power-density, high speed and fault tolerance are key requirements in aerospace. SPEED has been used for many applications including actuators, pumps, and starter-generators, including machines used in the most advanced aircraft.

Brushless PM machines and switched reluctance machines are the main technologies. In both of these areas, SPEED has new features improving the range of machine geometry, and the calculation of electromagnetic and thermal performance.

Hybrid & Electric as well as Commercial, Industrial, Agricultural & Mining Special Vehicles
 

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.

SPEED is behind the design of some of the world’s most efficient AC variable speed drives, using brushless SPM and IPM motor configurations. The code is used not only in high-efficiency industrial drives, but also in precision servomotor systems. We have made special efforts to extend SPEED into generators, with a new embedded EM Field Solver to cope with a wide variety of load specifications, and automatic calculation of generator characteristics for wound field synchronous generators. We have added the doubly-fed induction machine to the range. Improvements in machine geometry, EM field analysis, drive control, and thermal modeling have been achieved. SPEED’s technology covers all kinds of brushless PM machines, synchronous and switched reluctance machines, induction machines and DC machines. PM Axial-flux as well as PM linear machines can also be calculated. These programs are available on request (beta release).

Refrigeration, Domestic Appliances & Water
 

Efficiency requirements are driving these industries towards continual technological evolution, in a context of extreme cost pressure and material supply issues. SPEED is used as the main design tool in leading companies manufacturing compressors, washing-machine drive motors, pumps and fans worldwide. The technology covers induction motors (both 1-phase and 3-phase), permanent-magnet brushless motors, and line-start PM motors. Switched reluctance motors are also used in a few key applications. SPEED’s ability to characterize products and not just concepts is one of its main assets in serving this sector. Improvements have been made in all programs in relation to machine geometry, loss calculations, drive control, and EM field analysis.
