Torque Control of Brushless Direct Current Motor Drives Using Single Current Sensor with High Reliability

Due to the simple structure, high torque density, low maintenance, and high efficiency, brushless direct current (BLDC) motors are widely used in automation and industrial applications. A control strategy based on single current sensor is proposed for a four-switch three-phase BLDC motor system to lower cost and improve reliability. The whole working process of the BLDC motor is divided into si...

Modes of Oscillation of Trains of Bunches

In storage rings which operate with trains of bunches at high currents the observation of the motion of these bunches is quite important. An important reason is that the storage ring is often attempting to operate at or above the instability threshold for coupled bunch instabilities of the beam(s) and these observations are necessary to help to identify the cause of the instability and its poss...

Turbulent Pulsatile Pipe Flow with Multiple Modes of Oscillation

This study numerically investigates turbulent pipe flow driven by a pulsating pressure gradient. While studies of laminar and turbulent pulsatile pipe flow with a single mode of oscillating pressure gradient have been carried out extensively, there is scarce literature on pulsating pressure gradients with multiple temporal Fourier modes. In many real-life engineering applications, for example, ...
