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. An optimum design of rotor slot shape of induction motor for ... A rotor slot shape of induction motor for electric vehicle is optimized by FEM with the numerical techniques. To optimize the rotor slot shape, two objective function and 3 variables are defined, and the optimization algorithm is developed. ROTOR SLOT PERMEANCE HARMONICS UNDER DISTORTED AIR-GAP FLUX ... angle is intentionally injected into a cage induction motor to examine the effects of distorted flux waveform on rotor slot permeance harmonics. For the same air gap fundamental flux, the waveform which has the higher air gap peak flux also produce higher rotor slot permeance harmonics. The Optimal Design of Rotor Slot Geometry of Squirrel-Cage Type ...
INFLUENCE OF STATOR SLOT-SHAPE ON THE ENERGY CONSERVATION ASSOCIATED WITH THE SUBMERSIBLE INDUCTION MOTORS 3.1 INTRODUCTION The electric submersible-pump unit consists of a pump, powered by a medium-voltage three-phase induction motor. The power transmission system is integrated with riser-pipes. Pipe stacks are flanged together, and
Construction of Induction Motor - Circuit Globe Construction of Induction Motor The three phase induction motor is a preferable type of motor. It is mostly used in industrial drives because it is very reasonable and vigorous, economical and reliable.

Three Phase Induction Motors | Special Designs | Torque Motor Three Phase Induction Motors:. Three Phase Induction Motors are of two types: squirrel-case and wound-rotor. In squirrel-cage, the rotor consists of longitudinal conductor-bars shorted by circular connectors at the two ends while in wound-rotor motor, the rotor also has a balanced three-phase distributed winding having same poles as stator winding.
