Design and Analysis of Bearingless Permanent Magnet Synchronous Motor
Bearingless permanent magnet synchronous motor (BPMSM) has the characteristic of both conventional permanent magnet synchronous motor and traditional magnetic bearings. In this paper, the design and analysis of BPMSM by using Matlab/Simulink and ANSYS Maxwell are presented. The principle of electromagnetic force is utilized to ensure a stable levitation operation of BPMSM. The BPMSM mathematica...
متن کاملDesign and Implementation of a High-Precision Position Controller for Permanent Magnet Synchronous Motor Based on a New Gain Scheduling Approach
The direct drive permanent magnet synchronous motor (DD-PMSM) is a suitable choice for high-precision position control applications. Among various control methods of this motor, the vector control approaches especially the field oriented control has a high-performance in the industrial drives. In this method, the components of stator current are controlled independently and as a result, the tor...
متن کاملA Rotor Position/Speed Identification Method of Permanent Magnet Synchronous Motor for Low Speed Operating Condition and Parameter Perturbation ⋆
Accurate positioning of the motor requires high control performance for low-speed operation and motor’s parameter perturbation. In the AC motor vector control technology, the nonsingular higher-order terminal sliding mode observer of Insertion Permanent Magnet Synchronous Motor (IPMSM) is put forward based on the object current and voltage values to obtain the rotor position and speed signa. Th...
متن کاملDesign and Analysis of Novel Bearingless Permanent Magnet Synchronous Motor for Flywheel Energy Storage System
To effectively simplify system structure and improve power density and efficiency, a design for a motor/generator suitable for flywheel energy storage system (FESS) is proposed. The machine is an outer-rotor and coreless-stator-type bearingless permanent magnet synchronous motor (BPMSM) with a Halbach array. Firstly, the operation principle of the outer-rotor BPMSM is described. Then, the struc...
متن کاملSlotless Permanent Magnet Synchronous Motor Operation without a High Resolution Rotor Angle Sensor
An implementation for sinusoidal current control of a slotless Permanent Magnet Synchronous Motor (PMSM) with discrete Hall sensor position feedback is presented. To estimate the rotor position of the slotless PMSM, a flux estimation technique is used that takes advantage of the slotless machine’s characteristically low inductance to limit flux estimation error. The rotor position is estimated ...
