Unlike induction motors, which induce a secondary magnetic field in the rotor, PM motors useBeyond induction designs. The demand for more-efficient motors will continue as the demand forSalient-pole PM motors carry magnets buried in the rotor iron or placed in slots on the rotor surface. Wound Rotor Induction Motors | AC Motors | Electronics… A wound rotor induction motor has a stator like the squirrel cage induction motor, but a rotor with insulated windings brought out via slip rings and brushes. However, no power is applied to the slip rings. Their sole purpose is to allow resistance to be placed in series with the rotor windings while starting. In an induction motor the relationship between stator …

Induction Motor Interview Questions & Answers Instrumentation… In the induction motor design, the rotor slots are purposely made with a slight skew arrangement. It will not be parallel to the shaft.This problem can be prevented by proper choice of stator and rotor slots and also by skewing the rotor slots by one slot pitch. [UPDATED] Induction Motor Questions In the induction motor design, the rotor slots are purposely made with a slight skew arrangement. It will not be parallel to the shaft.The basic difference between an induction motor and a synchronous AC motor is that in the latter a current is supplied onto the rotor.
Oct 24, 2012 · Moreover, the high power density design of induction motor carried out varying with stack height, stator / rotor slot combination, slot shape, lamination, winding pattern, turns and material property of rotor bar. The design and performance of a new type of induction motor capable of extremely high power was described this paper with result of
number of conductors / rotor slots and I'r – equivalent rotor current in terms of stator current. and is given by I'r = 0.85 Is where is stator current per phase.Design of wound Rotor: These are the types of induction motors where in rotor also carries distributed star connected 3 phase winding. Design of Induction Motors.pdf - Free Download PDF • Rotor is the rotating part of the induction motor. The rotor also consists of a set of slotted silicon steel laminations pressed together to form of a cylindrical magnetic circuit and the electrical circuit.In order to get the above design details the designer needs the customer specifications. Why are the slots on the rotor of an induction motor… In Squirrel cage rotor, slots in lamination or rotor core is not made parallel to the rotor shaft. A slight angle is maintained due to some advantages.This is called the rotor Skew. Rotor of an Induction Motor skewed due to following reason… With the bar skewed,the amount of the bar cutting the field... Construction of squirrel cage induction motor explained
Induction Motor Rotor - Electrical Edition Induction Motor Rotor: Induction motors are available with two types of rotors basically.The rotor consists of a cylindrical laminated core with parallel slots for carrying the rotor conductors which, it should be noted clearly, are not wires but consist of heavy bars of copper, aluminium or alloys.
