Schematic symbol of a slip ring motor. A wound-rotor motor, also known as slip ring-rotor motor, is a type of induction motor where the rotor windings are connected through slip rings to external resistance. Adjusting the resistance allows control of the speed/torque characteristic of the motor.

Design of wound rotor Basic Requirements. Rotor consists of three phase winding to form same no. of poles in stator . Rotor winding is connected in star and open ends are connected to 3 slip rings mounted in rotor shaft. Rotor winding are shorted through carbon brushes riding on …

Mar 1, 2021 · Wound Rotor Induction Motor Definition: A wound rotor induction motor (also known as a slip ring motor) is defined as a type of 3-phase AC motor designed for high starting torque by connecting external resistance to the rotor circuit.

In Figure 1, the schematic diagram of wound rotor induction motor where three phases R, Y, B are shown and rotor slots are highlighted. Separately front view of stator and rotor are shown...

In the following wiring guide, we will show how to control the starting and speed control of the three-phase wound rotor (slip-ring) induction motor with the help of schematic, power and control wiring diagrams.

Fig.1: Wound Rotor Induction Motor. The stator of this motor has three phase star or delta connected winding similar to the stator of the squirrel cage induction motor. The rotor also carries a similar three phase star connected winding. Both stator and rotor are wound for the same number of poles.

Aug 25, 2011 · Fig-2 above is an electrical schematic diagram of a common control circuit which illustrates how the wound rotor motor is operated to run from standstill until it reaches its rated speed.

the following wiring guide, we will show how to control the starting and speed control of the three-phase wound rotor (slip-ring) induction motor with the help of schematic, power and control wiring diagrams.

FIGURE 2: RANDOM OR FORM WOUND The random wound rotor can be wound as a conven-tional lap winding, to reduce the connection time. Most form wound rotors use push-through coils, a wave winding, with only 1 or 2 turns/coil.

Dec 10, 2015 · The schematic symbol for a wound rotor induction motor is shown in Figure 44 – 4. Manual Control of a Wound Rotor Motor. The starting current and speed of a wound rotor induction motor is controlled by adding or subtracting the amount of …
