DIFFUL DEEP WELL PUMP---What is the induction motor
An induction motor,3 phase induction motororasynchronous motoris anAC electric motorin which theelectric currentin therotorneeded to produce torque is obtained byelectromagnetic inductionfrom themagnetic fieldof thestatorwinding.An induction motor can therefore be made without electrical connections to the rotor.[a]An induction motor's rotor can be eitherwound typeorsquirrel-cage type.
Three-phasesquirrel-cage induction motors are widely used in industrial drives because they are rugged, reliable and economical. Single-phase induction motors are used extensively for smaller loads, such as household appliances like fans. Although traditionally used in fixed-speed service, induction motors are increasingly being used with variable-frequency drives (VFDs) in variable-speed service. VFDs offer especially important energy savings opportunities for existing and prospective induction motors in variable-torque centrifugal fan, pump and compressor load applications. Squirrel cage induction motors are very widely used in both fixed-speed and variable-frequency drive (VFD) applications.
