Active sensing organisms, such as bats, dolphins, and weakly electric fish, generate a 3-D space for active sensation by emitting self-generated energy into the environment. For a weakly electric fish, we demonstrate that the electrosensory space for prey detection has an unusual, omnidirectional shape. We compare this sensory volume with the animal's motor volume--the volume swept out by the b...

Switched reluctance motor drive system has greatly practical value in electric vehicle applications. For the characteristics of switched reluctance motor and electric vehicle application requirements, how to reduce the torque ripple effectively and ensure its average output torque, all these become a hot spot of research. Based on this, first of all, the nonlinear model of switched reluctance m...

With the aggravation of environment pollution and the reduction of petroleum resources, the development of electric vehicle (EV) draws more and more people’s attention. In the EV research field, that seeking for a high efficient and reliable motor control method that suits the operating conditions and characteristics of the vehicle drive motor has become one of the key techniques that need to b...

For machine drive applications, multiphase induction motor could potentially meet the demand for high power electric drive systems which are both rugged and energy efficient. High phase number drives possess several advantages over conventional three phase drives such as high torque, higher reliability and increased power. Multiphase induction motors have found many applications such as electri...

Applying a unique 3-channel RS-485 transceiver displaying many unusual features increases reliability and fault-detection in motor-control applications. Designed specifically for motor shaft encoder applications, the MAX3097 and MAX3098 feature three differential channels to handle optical encoder data, ±15kV ESD protection, increased common mode rejection to -10 and +13.2V, three separate faul...
