Firmware version 4.8 allows Simotics synchronous reluctance motors to also be operated with Sinamics S120 converters, enabling them to benefit from the complex functionalities of the modular S120 product portfolio. The new Sinamics reluctance control license used in combination with the Sinamics Booksize Modules means that precise drive control down to a complete standstill is now possible with...

In this paper, the modeling and control of reluctance-force-based magnetic suspension in cylindrical rotor, ring-shape air gap, bearingless motors are presented. The full suspension system dynamics, including both the destabilizing force due to the motor field and the active magnetic suspension control forces, are modeled, and a transfer function of the bearingless motor suspension plant is der...

Switched Reluctance Motors (SRM) have inherent advantages such as simple structure with non winding construction in rotor side, fail safe because of its characteristic which has a high tolerances, robustness, low cost with no permanent magnet in the structure, and possible operation in high temperatures or in intense temperature variations. The torque production in switched reluctance motor com...

The concept of this work helps to develop a switched reluctance motor (SRM) drive. Because of salient feature like four quadrant, rigid structure, high-speed capability and low cost from other types of motors, switched reluctance motor is more predictable in high speed applications. Its on-board integrated charger is formed using the embedded motor drive components. Good driving and regenerativ...

By using the energy dissipation theory and the property of the switched reluctance motor, this paper presents a nonlinear controller for the planar switched reluctance motors (PSRM). Based on the fact that the electrical time constant is much smaller than the mechanical time constant, the whole PSRM driving system is treated as a two-time-scale system and can be decomposed into two subsystems (...

In this paper, we present a novel technique to estimate the position of the rotor of a switched reluctance motor by observing the characteristics of the vibration of the stator during the motor operation. This removes the need of the shaft position sensor which is known for its unreliability and problems associated with its application. Vibration in switched reluctance motors is generated mainl...
