8. The Industrial News of variable ac drive inverter
In 2013, the total electricity consumption of China's motors was approximately 3.4 trillion kWh, accounting for 64% of the total electricity consumption in the entire society. Among them, the total electric power consumption of the motor industry is 2.9 trillion kWh, which accounts for about 75% of the industrial electricity consumption. The adoption of industrial-controlled inverter devices can significantly increase the energy-saving rate of the motor, which is a key link in the development of a low-carbon economy.
Q1. How can What is a variable speed AC drive?
A1 : AC drives control the speed of either an induction motor or a synchronous motor by adjusting the frequency of the power supplied to the motor. AC drives are also known as adjustable speed drives (ASD) or adjustable frequency drives (AFD) or variable frequency drives (VFD) or variable speed drives (VSD) or frequency converters (FC).
Q2. What is sensorless Vector Control ?
A2 : Sensorless vector control is a technique used in variable frequency drives to rotate the force vector in the motor without the use of a shaft position sensor. The goal of ac sensorless vector technology is to give the user "dc" like control while making traditional speed or shaft position feedback from the motor unnecessary. The SV control removes a major source of complexity and potential for failure (the encoder feedback), while simplifying many ac drive installations. The sensorless vector algorithm must be tuned to match the characteristics of the particular motor being controlled by the drive, and improves torque performance at very low speeds as compared to typical Volts per Hertz control.
