Advanced Motor Control Algorithms for Reducing Power Consumption of Embedded Systems
The top consumers of electricity are HVAC systems, water
heating, lighting, office equipment, and machinery. More specifically,
the motors within these machine are responsible for approximately
two-thirds of the total electrical energy consumption in a typical
industrial facility. Motors are everywhere—blowers, pumps, compressors,
conveyors, machine tools, mixers, shredders and more. To improve the
efficiency and lower the operating costs of the electric motors in your
enterprise, certain factors need to be considered. Among these factors
are:
- Select a high efficiency motor
- Select the right size of motor
- Select the appropriate motor technology
- Use the appropriate control algorithms
Christian Fritz,
Product Manager at National Instruments, looks at these factors, as well
as a deeper look at the field oriented control (FOC)
algorithm--and
how to implement this algorithm using FPGAs--in this
technical paper.
