Slip Ring Motor for Steel Rolling Mills

A slip ring motor is an AC induction motor specially designed to meet the demanding requirements of steel rolling mills. It differs from regular motors as it features a wound rotor with three-phase windings connected to slip rings. These slip rings allow external access to the rotor windings, which are connected to external resistances through brushes.

The way a slip ring motor operates involves a two-step process. Firstly, during the starting phase, the rotor windings get connected to external resistances to limit the starting current and deliver a high torque at low speeds. This ensures a smooth and efficient start, preventing excessive wear and tear on the rolling mill equipment.

Once the motor reaches its operating speed, the external resistances are gradually short-circuited one by one, allowing the rotor windings to be directly connected to the power supply. This transition from the resistance-starting mode to the direct-on-line mode is seamless and guarantees smooth operation within the rolling mill.

The slip ring motor’s ability to control the starting current and provide high torque at low speeds is critical for steel rolling mills. It helps protect equipment from damage and ensures efficient operation by maintaining a constant rolling speed. By utilizing external resistances and slip rings, the motor can withstand heavy loads and meet the rigorous demands of continuous rolling processes in steel mills.

In conclusion, slip ring motors play a vital role in steel rolling mills by offering precise control over the starting current and torque. Their unique design allows for efficient and reliable operation, ensuring the smooth functioning of rolling mill machinery.
