Independent Control of Two Permanent-Magnet Synchronous Motors Fed by a Four-Leg Inverter

Independent Control of Two Permanent-Magnet Synchronous Motors Fed by a Four-Leg Inverter Abstract: This paper proposes a vector control strategy for independent control of two permanent-magnet synchronous motors (PMSMs) using a single four-leg inverter (4LI). An expanded two-arm modulation to obtain a balanced three-phase output voltage is described. This paper also proposes a method to […]


Sensorless Drive for High-Speed Brushless DC Motor Based on the Virtual Neutral Voltage

Sensorless Drive for High-Speed Brushless DC Motor Based on the Virtual Neutral Voltage Abstract: The brushless dc (BLDC) motor can be driven by either pulse-width modulation (PWM) or pulse-amplitude modulation (PAM) techniques. Unfortunately, neither of them can be the most suitable method for the high-speed BLDC motor in the wide speed range, so a hybrid […]
