What is the engine of the wound rotor?

wound engine engine is a three -phase induction variant that contains the capacity of speed control and during the start the current and increased torque value are significantly reduced. Conventional induction or squirrels of the cage have a rotor composed of laminated steel bars connected at one end. The wound engine rotors are profiled to accept three separate wire windings ended at three slip rings on the engine shaft. During the start, variable resistance is applied in the series with the rotor winding with harvest rings, resulting in a reduction in the overall initial outflow and increasing the available torque. This allows the use of smaller engines with high slip and load on inertia.

Machines such as heavy ventilation fans of large diameter, long conveyor belts and porridge are known as high inertia or high loads. In other words, due to their high inertial potential, they achieve considerable time at the start of the operating speed.If conventional engines control it would have to be evaluated to handle these extended periods of the running current and torque requirements rather than much lower running value. To achieve a functional solution, the engine, its appetizers and the power system would have to be much greater than necessary to actually start the machine. An alternative to this puzzle is the engine rotor engine.

The 4 rotor rotor of the wound rotor looks similar to the externally, but has an internal profile designed to suit three separate winding. This winding ends at three slip mounted at one end of the rotor shaft. During operation, a set of static carbon brushes on these rings run and connect the engine to a device with variable resistance. This allows the engine operator or an automated rotor changing system when the engine starts.

Increasing the ResistanceIt lives the overall current of the engine and increases the amount of torque available. Once the engine runs at full operating speed, the resistors are short -circuited, effectively replicating the conventional rotor. The gradual increases of resistance also allow the engine speed to change to some extent. These beneficial properties of the wound engine allow smaller motors and appetizers to install a high -flying machine, increasing the installation more efficient and cost -effective.
