Product Description

YR series type three-phase asynchronous motor, the stator structure, installation outside using coil end has reliable fixation and binding, rotor USES high strength paint BaoBian copper wire, coil high mechanical strength, collector ring and carbon brush device placed in the end cover, can prevent carbon foam dust pollution coil, easy disassembling and maintenance, in the process of manufacturing the turn-to-turn impulse withstand voltage test after many mechanic frequency of pressure test, stator winding using F solventless insulation varnished, and after 140 oC high temperature drying fixed-line treatment, insulation performance is stable and reliable, junction box has a separate grounding terminals.
YR series motors can be started using the rotor resistance pressure, unique to start down, start torque, high efficiency, low noise, little vibration, reliable operation, easy installation and maintenance, etc.
YR series motors are widely used in mining machinery equipment.Such as the winch hoist, ball mill, the blower, water pump and wire drawing machine, rolling mill machinery and equipment, etc.
YR series motor required environment temperature 15 oC - - 40 oC, the poster does not exceed 1000 m, rated voltage 380 v, can according to customer's requirements into 660 v, rated frequency 50 hz, S1 duty, protection grade IP23, rated temperature 80 oC, B3 installation.

Remark: When starting this type of motor, the starting varistor must be connected to the rotor circuit of the motor. It is not permissible to short-circuit the rotor windings directly.

YR AC slip ring has the advantages of high efficiency, strong overload capability, low noise, low vibration, reliable structure and beautiful appearance. The motor casing is a rigid cast iron casing, and the motor slip ring is located outside the non-bearing end for easy replacement and maintenance.
