Speed control of an AC motor requires a three phase supply that can vary both voltage and frequency. Such a supply creates a variable speed rotating field in the stator that allows the rotor to spin ...

This paper presents the system concepts and describes the circuit implementation of several key features. The increasing use of high-current brushless dc (BLDC) three-phase motors puts stringent ...

Precise motor control has gained greater significance as electrification takes over the automotive industry. Whether for electronic power steering, electronic stability control, automatic braking ...

NEC Electronics’ (distribution: Gleichmann Electronics) two new 3-phase control device families, V850E/IF3 and V850E/IG3, open up all kinds of new application possibilities. Key features of these ...
