One important advantage of the synchronous motor is …...From your message, you are installing a wound rotor motor on a ball mill. The wound rotor motor is usually used on this application because of it's superior starting characteristics. The Wound Rotor motor is able to develop a very high starting torque from zero speed to full speed at a relatively low start current.
Wound rotor motors are an extremely versatile breed of induction motors. Featuring a rugged design, these machines provide the unique ability to gradually bring up to speed high-inertia equipment and large loads smoothly and easily. Wound rotor motors also can develop high starting torque at standstill - while maintaining low inrush...Wound Rotor Motor (Slip-ring) Vound rotor motors are used where it is necessary to start the motor with a current inrush limitation lower than that which can be met successfully by a squirrel cage motor or a synchronous motor. Wound rotor motors are reliable drives for large ball mills, large presses, variable speed pumps, rolling mills, cen
We operate ball mills with dual-coupled 3500hp 4160v wound rotor induction motors. We have recently experienced frequent arcing of the slip rings which seems to start on the center ring. The arcing damages the ring badly which requires us …...Wound Rotor Motors also can develop high starting torque at standstill while maintaining low inrush. What makes the Wound Rotor Motor a unique induction machine is its rotor. Instead of a series of rotor bars, a set of insulated rotor coils is used to accept external impedances.

YRQ wire-wound slip ring motor is a wire-wound asynchronous motor specially developed and designed for the ball mill system, which conforms to the IEC standard. This series of motors has the advantages of simple structure, safe and convenient use, high starting torque, high overload capacity, high efficiency and energy saving, and it is the ...A very basic overview, but the advantage of wound rotor slip ring motor is that, through a LRS u can vary the resistance of the rotor. The advantages are 1. able to manipulate the torque speed curve, allowing u start with a much higher torque. Wound motors are suitable for application with heavy starting duties such as ball/sag mills, crushers etc.
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 inserting high resistance into the rotor circuit; as the …...I am involved in converting a ball mill, which requires a large amount of starting torque, from a slip ring motor driven application to a vfd driven appl. .
