Traction asynchronous electric motor type DATCH 180-4

Connecting, overall dimensions as at engines "PEMZ", "BEMZ". The weight is less than the motor "PEMZ", with preservation of ???.Works in the range 0 4500 rpm, in the mode S2 60 min. according to GOST IEC 60034-1. Cos, efficiency is higher than analogues. The stator winding uses insulation with increased breakdown voltage and double impregnation, which increases the operational characteristics. The revolutions control system is effectively protected, as the gear wheel with involute tooth shape with modulus M=1,75 and teeth Z=96 is used. The design provides for the possibility of installation with tines downwards. For installation in a trolleybus, the design provides holes for eyebolts M24. Imported bearings are installed in the motor. In the outer cover on the drive side there is a collar - CR 80x105x10 HMS 5V and oiler 2.2.45 Ts6 GOST 19853-74. Bearing grease MC1510 BLUE. Bearing on the side of speed sensors works without grease replenishment during 1,5-2 years.
