This leads to higher induced currents in the conductor generating higher …
WebAug 25, 2024 · In the double-cage rotor there are two layers of rotor bars. The double cage induction motors are used for obtaining high starting toque at low starting current. The stator of a double cage induction motor is similar to that of an ordinary squirrel cage induction motor. Each layer of the rotor is short circuited with the help of end rings. WebFor very large inertia loads or loads that must be accelerated quickly, a motor having a high starting torque should be applied. The National Electrical Manufacturers Association (NEMA) provides design letters to …
WebOct 26, 2024 · Reduced voltage starting of three-phase AC induction motors can be used to reduce the starting current drawn by the motor. ... so any reduction in the start voltage results in a greater difference in starting torque between the high and low starting torque motors. In many applications, the starting current is required to be less than 300% FLC ...
