A wound rotor motor is a variation of the three phase induction motor, designed to provide high starting torque for loads with high inertia, while requiring very low current. Wound rotor motors are also referred to as "slip ring motors."

احصل على السعرIn slip ring motors, the rotor resistance is increased by adding external resistance. If the rotor resistance is high, the slip is more, thus it's possible to achieve "pull out" torque even at low speeds. When the motor reaches its base speed (full rated speed), as the
احصل على السعرSlip ring Induction Motors Starting of (i) Rotor slip ring induction motors are practically always started with full line voltage applied across the stator terminals. The value of starting current is adjusted by introducing a variable resistance in the rotor
احصل على السعرOld slip ring motor systems typically consist of a liquid resistance tank with an electrode, or else a series of cast iron or wire wound resistor banks with a changeover switch. These systems require mechanical intervention for motor starting, can become mechanically unreliable, and
احصل على السعرThe connection diagram of the slip ring starter induction motor is shown below. Full starting resistance is connected and thus the supply current to the stator is reduced. The rotor begins to rotate, and the rotor resistances are gradually cut out as the speed of the motor increases.
احصل على السعرSlip ring motors or wound rotor motors are a variation on the standard cage induction motors. The slip ring motor has a set of windings on the rotor which are not short circuited, but are terminated to a set of slip rings for connection to external resistors and contactors.

احصل على السعرWhen the stator winding of the slip ring motor is connected to the three phase supply, it produces a rotating magnetic field in the same way as a squirrel cage induction motor. This rotating magnetic field induces voltages in the rotor windings and a rotor current will flow through the closed circuit, formed by the rotor winding, the slip rings, the brushes and the star connected external
احصل على السعرMotor Starting Resistors are necessary because the self resistance of a motor armature is very low. When the voltage is first applied, excessive current will flow. For limiting this current, since there will be no resisting back electromotive force (emf),some series resistance can
