To provide an indication motor rotor capable of improving motor performance by concentrating portions under magnetic saturation conditions of rotor teeth. The rotor of an induction motor of this invention may include slots formed approximately in the shape of a T. The slots may be formed so that top slots are arranged on an outer peripheral portion of a rotor core, and bottom slots are ... Wound Rotor - TECO-Westinghouse motor life is ensured with the use of external resistor banks or liquid rheostats that dissipate heat build-up generated during motor start-up. What makes the wound rotor motor a unique induction machine is its rotor. Instead of a series of rotor bars, a set of insulated rotor coils is used to accept external impedances. Squirrel-cage rotor - Wikipedia A squirrel-cage rotor is the rotating part of the common squirrel-cage induction motor. It consists ... The motor rotor shape is a cylinder mounted on a shaft. ... The rotor has a larger number of slots than the stator and must be a non-integer ...

Design of Induction Motors
In designing rotors for induction motors, the shape and dimensions of the slots have a demonstrable effect on the performance characteristics of the motor. The slot (bar) shape can be seen in the lamination examples in the photo. Another design factor common to most squirrel cage induction... A Review on Influence of Rotor Geometry on the Performance…
Optimal Design of Rotor Slot Geometry of Squirrel-Cage Type ... Three geometries of rotor slots and of bars cross-section, keeping the same cross-section area, are considered: rectangular shape, stepped shape and step-holed shape. This study is based on the finite element analysis of the induction motor where only the rotor slots and bars cross-section configurations change from an application to another. Optimal Shape Design of Rotor Slot in Squirrel-Cage Induction ... Abstract: Induction motors are widely used in various industrial applications with different torque-speed characteristics. Since the configuration of the rotor slot has a great impact on the electromagnetic torque-speed characteristics, a design optimization process is necessary to improve the motor performance of the induction motor. Advantage of Skewed Stator Slots in the Rotor of Induction ...
