Position Estimation of the PMSM High Dynamic Drive at Low Speed Range
Permanent Magnet Synchronous Motors (PMSM) are widely used in industrial drives due to their high power density, high torque-toinertia ratio, small torque ripple and precise control at low speed range, possibility to torque control at zero speed, high efficiency and small size. To exploit presented advantages, a vector control should be used. Vector control allows the drive a good dynamic, effe...
متن کاملResearch on the Torque and Back EMF Performance of a High Speed PMSM Used for Flywheel Energy Storage
Due to advantages such as high energy density, high power density, rapid charge and discharge, high cyclic-life, and environmentally friendly, flywheel energy storage systems (FESs) are widely used in various fields. However, the performance of FES systems depends on the performance of a high speed machine, therefore, the design and optimization of a high efficiency and high power density machi...
متن کاملSensorless Speed Estimation of PMSM near Zero Speed Using Online Short Time Fourier Transform Ridges
There are many sensorless schemes that have been proposed to estimate the rotor speed and position. However high frequency signal injection methods are able to detect the rotor speed and position even at zero speed whereas other schemes fail. Conventionally such methods use estimators based on the phase locked loop structure, which involves some restriction to maintain stability and track accur...
متن کاملMinimization of Torque Ripple for a 4-ø BLDC Motor with Non-Ideal Back Emf by using Phase to Phase Back-Emf Estimation
Abstract— Brushless motors are gaining attention from various Industrial manufactures because of its high efficiency, noise less operation and high speeds. In conventional control methods of Brushless Dc motors, the back electromotive force is assumed to be in ideal form i.e., Trapezoidal form, so that rectangular currents are injected from the inverter. In real time, the back-Emf may not to be...
متن کاملSensorless Resonance Tracking of Resonant Electromagnetic Actuator through Back-EMF Estimation for Mobile Devices
Resonant electromagnetic actuators have been broadly used as vibration motors for mobile devices given their ability of generating relatively fast, strong, and controllable vibration force at a given resonant frequency. Mechanism of the actuators that is based on mechanical resonance, however, limits their use to a situation where their resonant frequencies are known and unshifted. In reality, ...
