High-speed applications are emerging in the last years in the automotive industry, representing a major challenge for the electric actuation technologies. One of the proper candidates for these actuation systems is the permanent magnet synchronous motor (PMSM) due its performance parameters (good energy efficiency, and low-noise operation). The paper proposes to provide an overview of high-speed electric actuation for automotive applications. The field of high speed automotive applications includes heating, ventilation and air conditioning (HVAC), air compressors for fuel cells, water pumps, and turbochargers. Solutions based on permanent magnet synchronous motors (PMSM) will be offered. Crucial issues like motor design and analysis, materials, construction, manufacturing technologies, motor control, and power electronics will be presented. Case studies, which consider slotless permanent magnet synchronous motors, will be presented with experimental results. Some novel solutions are proposed taking into account interior permanent magnet synchronous motors (IPMSM) with concentrated (non-overlapped) windings.
