YRKK Series Air-Air Cooled High Voltage 6KV 10KV Wound Rotor Slip Ring Motor

YRKK series Medium Size Three Phase Asynchronous High Voltage Slip Ring Motor, also called as high voltage wound Rotor motor, YRKK series large-scale high voltage wound rotor three-phase asynchronous motors are our new generation products designed and manufactured by the technical personnel of our company who summarized more than ten years trial manufacture experiences and absorbed the advanced technique abroad. The mounting dimensions, power grades, electrical performance of these motors all comply with the national standard GB755-2000 Rotating electrical machines–Rating and performance and relevant IEC international standard. Compare with the national design project previous, these motors adopted advanced technical result of the motor industry in recent years more, therefore the configuration is more reasonable, and the craft is more advanced, the motors are with features of high efficiency and power factor, low noise and vibration, reliable performance and convenience for mounting and maintaining.

The junction box of the stator is located at the right side of the motor generally (viewed from the end of shaft extension), it can be also located at the left side of the motor under the order request, one ground terminal has been set in it.

YRKK Series Air-Air Cooled High Voltage 6KV 10KV Wound Rotor Slip Ring Motor Configuration

The motor has a box structure and the base is welded by steel plate. Its configuration is compact and comfortable, thus the rigidity and stability is good; There is a closed air-air cooler on the top of the motor, it is convenient for disassembling and mounting .The slip ring is located at the unloaded side out of the base, it have inspection windows on two side, it is convenient for the maintenance and repairing of the motor.

The stators of our motors are mounted by reasonable press craft to parallel work and shorten the production period; The windings are made of class F insulation materials, temperature rise will be considered on class B to extension the life; At each end there are reliable fastness and colligation. During processing, they are suffered many times of pulse voltage tests on windings interlayer and voltage endurance test to ground, and the motor has excellent insulation, strong mechanical and fine moisture protection.

The wound rotor is the copper bars configuration, the windings are made of class F insulation materials, and the reliable fastness and colligation are adopted for end parts of the windings to ensure the reliability of the motor operation.

YRKK Series Air-Air Cooled High Voltage 6KV 10KV Wound Rotor Slip Ring Motor Application

These motors can be used to drive Windlass, Press machinery, Crusher, Stock-removing, drawbenchs and other general-purpose machinery. They can serve as the prime movers in steel, mines, mechanical industries, blower, compressor, transportation, building materials industry, etc field.

Advantages of A Slip Ring Induction Motor

Bulletproof Motors’ slip ring induction motors have a welded sheet steel structure as standard, which allows a light structure and increases the rigidity of the motor. The stator and rotor are precision molded in one piece to reduce energy loss and therefore improve the quality of the output. In slip ring motors of the Bulletproof high voltage series, the stator coil is double-layered and the core is stacked and assembled with coils on the outside of the frame, applied on the circumference of the ends of the stator coil with spacers to improve rigidity. Once completed, the stator winding is placed in a vacuum tank, impregnated and inserted into the stator frame. The standard design of the rotor in wound rotor induction motors / slip ring motors and ring collector is made with a copper or copper alloy bar.

We pay attention to product quality, focus on customer experience, and is one of the most outstanding companies in the domestic and foreign High voltage modular induction motors, High Voltage Three-phase Induction Motors, 11kv motor industry.
