Three-phase asynchronous motors 6AMU series with a squirrel-cage rotor designed to drive pumping units in oil fields. Engines are manufactured for deliveries to areas with moderate (version U1) and cold (version UHL1) climate with outdoor installation. The motors are designed to operate on AC mains with frequency 50 Hz, tension 380 V. Insulation class – F. Protection class IР54. Executions according to the installation method IM1081 in accordance with GOST 2479: Motors are designed for S1 duty (long lasting) according to GOST 183. According to the degree of resistance to external influencing factors, the motors correspond to the M1 group according to GOST 17516.1. Vibration class of motors 1.8 . Cooling method for motors – IC0141 according to GOST 20459. The motors have an input device K-3-2 with two unions. Temperature protection sensors type CT14-2 with a response temperature of 145 are built into the stator windingº. Structurally, the motors allow for articulation with the drive by means of a V-belt transmission.
