A wound rotor induction motor (also known as a would round motor or slip ring induction motor) is defined as a special type of 3 phase AC induction motor designed to provide high starting torque by connecting an external resistance to the rotor circuit. The motor's rotor is a type of wound rotor. Hence why it is also known as a wound rotor or

Wound rotor 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. Wound-rotor motors can be started with low inrush current, by

Since the speed of a wound rotor induction motor may be controlled over a range of 50-100% by inserting resistance in the rotor, we may expect the same of the doubly-fed induction generator. Not only can we slow the rotor by 50%, but we can also over speed it by 50%. That is, we can vary the speed of a doubly-fed induction generator by ±50%

Wound Rotor Induction Motors (WRIMs) are a type of induction motor characterized by their rotor construction. Unlike the more common squirrel-cage rotor found in standard induction motors, the rotor in WRIMs is composed of a winding wire that is similar to the stator winding. The key features of WRIMs include:

Wound rotor motors are a specialized type of AC motor and work in much the same way that other induction motors function. They consist of two main components, the outside stator, and the inside rotor, which are separated by a small air gap. The stator is generally the same across all induction motors, and consist of metal laminations that hold

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.". The stator of a wound rotor motor is the same as a typical induction motor, but the rotor has a three

Wound Rotor Induction Motors. 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.

These are variable-speed wound rotor induction generators with two bidirectional back-to-back voltage-source converters, as shown in Fig. 6.10. The three-phase stator winding is directly connected to the grid. The three-phase rotor windings are connected to a voltage-source inverter via slip rings. This rotor-side inverter injects three-phase

The control strategy consists of decreasing the rotor resistance as the rotor speed increases from zero to the rated value of 1 per-unit (p.u.). Logical operations compare the rotor speed p.u. value with 50%, 70%, and 90% thresholds to trigger switching events in the resistor bank that disconnect sections of the resistance banks sequentially.
