YR high voltage slip ring motor is general-purpose wound rotor three-phase asynchronous motors, which are newly designed and updated products. Its power rating and installation dimensions comply with IEC standards. The protection grade of the motor shell is IP23, the cooling method is IC01, and the continuous working system (S1) is suitable for clean places without flammable, explosive, and corrosive gases.
YR series (IP23) three-phase asynchronous motors adopt class B insulation. Rated voltage is 6kv, rated frequency is 50HZ, △ connection method, motor structure and installation type are IMB3 (frame with feet, end cover without flange, horizontal type), all without brush structure. The altitude of the motor operating location does not exceed 1000m, and the ambient air temperature varies with the seasons, but does not exceed 40°C
Type: YR slip ring motor
Speed: 2/4/6/8/10/12/16 poles

YR series medium size high voltage three-phase induction motors can provide a larger starting torque at a smaller starting current; it has high efficiency, energy saving, Applicable to the feed line capacity is not enough to start the squirrel-cage rotor motor, a longer starting time and more frequent starting, speed and other occasions within a small range. Such as dragging hoists, rolling mills, wire drawing machines, etc. When starting the motor, a starting varistor must be connected in the rotor circuit in advance. It is not allowed to short-circuit the rotor winding directly to start.
