Speed estimation during the starting transient of induction motors
(Institute of Electrical and Electronics Engineers, 2020-07)
Typically, the rotor speed of electric motors was measured directly by the use of electromechanical sensors. Even though these devices are very precise, they are also fragile and expensive to install. Currently, some ...
