A Slip Ring induction motor can be started with external resistance added in its rotor circuit. But how does external resistance aid in better starting characteristics? Read here to know about the starting arrangement and the role played by the external resistances in obtaining better starting characteristics. Also know about the qualities of slip ring induction motors.

The starting characteristics and torque performance of slipring motors make them an optimal match for conveyors, mills, crushers, fans and other equipment in the mining and cement industries. Slipring motors can deliver high starting torque while drawing low starting current, and they continue to supply high torque over the entire speed range.

If the motor is started directly, without starter: The current absorbed by the motor during the start is extremely high. For example, a 110 kW motor with a nominal current of 205 A and a ratio starting current / nominal current equal to 6 absorbs 1230 A during the start.
Slip ring motors are usually applied on high inertia loads or on high resistant starting torque loads. The most common loads driven by these motors are: ball mills, of maintenance once they allow the brushes to be in contact with rings only during motor starting.. 50,000kW (70,000HP) and voltages up
of slipring motors make them an optimal match for conveyors, mills, crushers and fans in cement plants. High starting torque from slipring motors also helps minimise mechanical stresses on the driven equipment, increasing the lifetime of the equipment and reducing maintenance needs. Slipring motors can deliver high starting torque while
#0183;#32;7. Slip Ring Induction Motor. It has high starting torque and large overload capacity. The speed of slip ring induction motor can be changed up to 50% of its normal speed. Slip ring induction motor is used for those industrial drives which require high starting torque and speed control such as lifts, pumps, winding machines, presses, line shafts, elevators and compressors etc.

WEG has launched a new M (for mining) series of slip ring motors. Available in frame sizes IEC 355 to IEC 1000, the new motors cover the power range from 250 kW to 10 MW at 50 Hz or 60 Hz line frequency. These threephase induction units have between 4 and 14
Slip ring motors are the motors of choice whenever high starting torque or low starting current are required. They are especially suitable for heavy load inertia applications. Already since 1927, we are a global manufacturer, supplier, and distributor of large slip ring motors up to 8000 kW and 13800 V.
In 2009 the customer ordered the first Menzel motor. Since then the customer follows up with the orders for medium voltage motors in double digits. The additional production line designed for the customer in 2013, is equipped exclusively with Menzel motors. Satisfied customers come back! Cement mill slip ring motor Technical charcateristics:
TECOWestinghouse Motor Company synchronous machines are available with brush rigging and collector rings. The complete assembly is designed for long life and is easily accessible for inspection and routine maintenance. Made of steel or copper alloy, the collector rings are shrunk onto a steel mandrel over a Micarta#174; insulation sleeve.
