Rotor position estimation of switched reluctance motors based on damped voltage resonance [PDF]

, 2010
This paper proposes a method to obtain the rotor position of switched reluctance motors by means of voltage measurements. It is shown that the combination of motor and power-electronic converter defines a resonant circuit, comprised by the motor phase ...

Navigating the Double Edge of Product‐Service Systems: User Behavior, Adoption, and Rebound Effects

Business Strategy and the Environment, EarlyView.
ABSTRACT Product‐service systems (PSS) have been considered a promising approach to operationalizing the circular economy. Although many studies have outlined the potential sustainability gains of PSS solutions, it is still unclear what factors drive PSS adoption and how behavioral changes result in rebound effects, undermining their potential ...
