TL;DR: In this article, the authors analyzed the behavior of discrete-time current regulators for ac machines operating at high ratios of fundamental-to-sampling frequencies, a situation common for high-speed automotive drives and large-traction drives.

TL;DR: In this article, a method for recharging an electric storage battery in the charging system of an electric vehicle from an electric utility power grid includes determining the length of time required to recharge the battery, determining the desired time when the recharge is to be completed, transmitting to the electric power utility the length and desired time, and recharging the battery from the utility grid during a period when projected load demand is lower than peak demand and ending no later than a desired time.

TL;DR: In this article, a method to estimate the magnet temperature in surface permanent-magnet machines using high-frequency carrier signal injection is proposed. But the method is limited to the case of a single rotor.

TL;DR: In this paper, a method to estimate the magnet temperature in surface PM machines (SPMSM) using high frequency carrier signal injection is proposed, where the high frequency signal is injected intermittently in order to minimize potential adverse effects on the normal operation of the machine.
