The same real-time early warning signals that prevent drones from losing control could one day tell your self-driving car that something is about to go wrong.

Vector Robotics has completed a milestone 24-hour, 5-minute continuous electric flight with a small 3.1 kg UAV. Proving that persistent aerial coverage doesn’t require massive, noisy, ...

The design of different three-phase brushless DC motors and how they generate torque. How magnetics, construction, and other factors impact torque, speed, and smoothness in BLDC motors. General ...

There are two inevitable imperatives when it comes to EV motors: the integration of wide-bandgap (WBG) power electronics and the need for high-accuracy motor control techniques. For one, as 200mm SiC ...

Abstract: Wind energy is a fast-growing renewable energy source that helps reduce greenhouse gas emissions and supports sustainable power solutions. However, managing wind turbines efficiently and ...

The sliding mode observer (SMO)–based sensorless control is essentially a discontinuous switching control algorithm. Therefore, there is large speed or torque chattering in the permanent magnet ...

In order to reduce the chattering caused by the discontinuity of the control function in the traditional sliding mode observer (SMO), this article proposes a sliding mode observer with phase-locked ...

Demand for low-cost, robust motor drives has spurred increased use of sensorless vector control of induction and BLDC motors — in everything from consumer products to industrial applications, in ...
