Final answer:
Another name for a sensorless vector drive is the indirect vector drive. This type of drive is used to control the speed and torque of an electric motor without the need for an additional sensor. It uses mathematical models and algorithms to estimate the rotor position.
Step-by-step explanation:
Another name for a sensorless vector drive is the indirect vector drive. This type of drive is used in electric motor control systems to accurately control the speed and torque of the motor without the need for an additional sensor to provide feedback. The sensorless vector drive uses mathematical models and algorithms to estimate the rotor position and adjust the control scheme accordingly. By doing so, it can achieve high performance control just like a sensor vector drive, but at a lower cost.
