Project Description
YR (YRKK, YRKS) series 6kv, 10kv high-voltage three-phase asynchronous motor is a winding type (slip ring) three-phase asynchronous motor with closed air-water cooler. The protection grade of the motor is IP44 or IP54 (see GB / T4942.1), and the cooling method is IC81W (GB / T1993). The motor has the advantages of high load rotational inertia, high efficiency, energy saving, low noise, low vibration, reliable performance, convenient installation and maintenance, etc. This series of motors can be used to drive various machines. Such as ventilator, compressor, water pump, crusher, cutting machine tool and other equipment, and can be used as the prime mover of coal mine, machinery industry, power plant and various industrial and mining enterprises
YR (YRKK, YRKS) series 6kv, 10kv high voltage motors with box type steel structure, can be observed its interior after removing the cooler or protective cover, and esay to be installed and maintained; Wound rotor is installed with slip ring structure; Insulation class F stator made by VPI process, ensure the reliability of insulation, moisture-proof and shock resistance; Temperature senor for stator and bearing, non-stop oil filling and exit pipe, improve the protection ability and operation efficiency of the motors.
YR (YRKK, YRKS) series 6kv, 10kv high voltage motors can be applied to the requirements as follows: 1. The lager starting torque; 2. Power capacity is not enough to start a squirrel cage motor; 3. Long start time or start more frequently; 4. Adjust speed in a small range.

Description and application:
YRKS series Medium-Size High Voltage 3-Phase Asynchronous Slip Ring/ Wound Rotor motor is suitable for poor surroundings, the site in high required protection and directly application of outdoor. The motors can drive water pump, compressor, transportation machinery and common used machinery.
YRKS series motor is design into box-type construction. The frame is light in weight and good in rigid and is made of steel plates by melding. Air-water cooler is fixed at the top of frame with bolts and consists outside wind circuit in secondary cooling with water pump and water pool for motor, the primary cooling circulation is consisted of fan, cooler inside motor. The primary cooling medium (air) can complete the heat exchange with secondary cooling medium in cooling pipe (circulation water) through outside surface of pipe in the cooler as well as spring etc. heat transfer conductor.
