The stator–rotor slot combination is an important parameter in the design of high-voltage induction motor (HVIM). Low stakes online poker tournament strategy free. The different design of the stator–rotor slot combination will have an effect on the performance of the HVIM, such as torque, air-gap flux density, loss and so on. In order to analyze its influence, 10 kV, 1000 kW HVIM is taken as an example and the finite element. A theory of coexisting stationary and rotating slot openings is developed with the aid of ``revolving permeances,’ and the magnitude and speed of the parasitic fluxes due to the slot openings and the fundamental current density wave are found. It is shown that the interaction of the fundamental flux and a parasitic flux of the same order of magnitude as the fundamental flux causes the. The minimum value of slot pitch of a 3 phase induction motor is 15 mm. Write the formula for air-gap in case of three phase induction motor in terms of length and diameter. The length of air-gap, lg = 0.2 + 2 SQRT (D L) in mm. During grid motor starting from zero rpm, this starting current flow is in the upper part of the bar close to the rotor OD. (due to the skin effect of current penetration). AS the motor increases speed the bar current is distributed down in the lower part of the bar & the frequency seen by the bar decreases (decreasing slip). The manual design of induction motor is the combination of lengthy calculations and special attention. The possible stator-rotor slot combinations for four pole.
