Minimization 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 Speed Control of Brushless DC Motor with Fuzzy Based Estimation
This paper describes a simple way to control the Brush Less DC Motor (BLDCM) for electrical applications. To control this machine it is generally required to measure the speed and position of rotor by using the sensor because the inverter phases, acting at any time, must be commutated depending on the rotor position. The position sensors make the motor system more complicated and mechanically u...
متن کاملA Back-EMF Estimation Error Compensation Method for Accurate Rotor Position Estimation of Surface Mounted Permanent Magnet Synchronous Motors
This paper proposes a back electromotive force estimation error compensation method for accurate rotor position estimation of surface mounted permanent magnet synchronous motors. When estimating the rotor position of surface mounted permanent magnet synchronous motor sensorless drives, a direct current offset error component occurs in the voltage sensor. As a result, the rotor position is disto...
متن کاملBack EMF Observer Based Sensorless Four Quadrant Operation of Brushless DC Motor
Brushless DC (BLDC) motor drives are becoming more popular in industrial, traction applications. This makes the control of BLDC motor in all the four quadrants very vitalThe motor is operated in four steady state operating modes of torque-speed plane. To control a BLDC machine it is generally required to measure the speed and position of rotor by using the sensor because the inverter phases, ac...
