AC Induction Motor Rotor Design - Wolfram Demonstrations… You can adjust the three principal parameters related to induction motor rotor design. Approximate values for three specific NEMA designs are provided by means of buttons.The buttons provide a quick means of setting the parameters to the approximate NEMA design types of A, B, and D. 2. Rotor of 3-Phase Induction Motor 2. Rotor of 3-Phase Induction Motor. The rotor, mounted on a shaft, is a hollow laminated core having slots on its outer periphery.The difference between the synchronous speed Ns of the rotating stator field and the actual rotor speed N is called slip in a three phase induction motor. Laws of physics make it prohibitive to design ac-…

The impact of the rotor slot number selection on the induction motors is investigated. Firstly, analytical equations will reveal the spatial harmonic index of the air gap magnetic flux density, connected to the geometrical features and the saturation of the induction motor. Squirrel-cage rotor - Wikipedia In 1888, Nikola Tesla received a patent on a two-phase induction motor with a short-circuited copper rotor winding and a two-phase stator winding. Developments of this design became commercially important. In 1889, Mikhail Dolivo-Dobrovolsky developed a wound-rotor induction motor, and shortly afterward the cage-type rotor winding. By the end ... Solved problems: Design of Rotor - Induction Motors During the stator design of a 3 phase, 30 kW, 400volts, 6 pole, 50Hz,squirrel cage induction motor following data has been obtained. Gross length of the stator = 0.17 m, Internal diameter of stator = 0.33 m, Number of stator slots = 45, Number of conductors per slot = 12. Based on the above design data design a suitable rotor.
