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...

Magnetic force driven nanogenerators as a noncontact energy harvester and sensor.

Nanogenerator has been a very important energy harvesting technology through directly deforming piezoelectric material. Here, we report a new magnetic force driven contactless nanogenerator (CLNG), which avoids the direct contact between nanogenerator and mechanical movement source. The CLNG can harvest the mechanical movement energy in a noncontact mode to generate electricity. Their output vo...
