Determining torque induction motors
Weba motor is determined by the power supply and the number of poles built into the structure of the winding. With a 60 cycle power supply the synchronous speeds available are 3600 RPM, 1800 RPM, 1200 RPM and 900 RPM. Induction motors develop their torque by operating at a speed which is slightly less than synchronous speed. WebAug 19, 2024 · A 3 phase squirrel cage induction motor is a type of three phase induction motor which functions based on the principle of electromagnetism. It is called a ‘squirrel cage’ motor because the rotor inside of it – known as a ‘squirrel cage rotor’ – looks like a squirrel cage. This rotor is a cylinder of steel laminations, with highly ...
