Description
Our enterprise implements electric motors in assortment.

AIM, AIMM 90-280, AIU 90-250 and VAIU 112-200 series
with power binding to leading dimensions in accordance with GOST 28330 (RS 3031-71).

Explosion-proof asynchronous motors with the squirrel cage rotor are intended for work from network of three-phase alternating current, with a frequency of 50 Hz and 60 Hz for the drive of stationary machines explosive productions coal (AIU, VAIU engines), to the chemical, gas, petroleum industry (AIM, AIMM engines).

Engines are manufactured for deliveries to the countries with moderated (with type of climatic modification of U2, 5) and tropical (with type of climatic modification of T2, 5) climate. AIMM 90 - 160 engines have also execution of OM2, B5 (for sea vessels). AIMM 180 - 280 engines with execution of OM2, B5 are at development stage.

The binding of capacities of engines to the adjusting and connecting sizes corresponds to PC 3031-71.

Are calculated for work in the S1 mode, operation of engines in the S2, S3, S4 modes at one of standard tension from 220B to 660B is allowed. VAIU engines are manufactured on tension of 660/1140 Century.

In coordination with the manufacturer engines with power supply from frequency and adjustable converters can be manufactured.

Marking of explosion protection of engines:

  • AIM90, AIMM90 series, 100 - 1 ExdllBT5/2ExdllCT5
  • the AIMM112 series - 1 ExdllBT4/2ExdllCT5
  • ExdllBT4/2ExdllCT4 AIMM 132-180 - 1 series;
  • the AIMM200 series - 1 ExdllBT4
  • the AIMM225-280 series - 1 ExdllBT4/2Exdll(H2)
  • AIU90-250 series, VAIU112-200 - RV of STARS

Degree of protection of engines: IP54. By request of the consumer AIMM132-280 engines can be manufactured with degree of protection of IP55. Class of heat stability of isolation of engines "F" (VAIU engines - class "H"). Engines of the AIMM280-1 series are manufactured with winding of rigid coils.

Engines are manufactured the following executions on mounting mode in accordance with GOST 2479:

  • on paws - IM1081 (for AIMM280 - IM1001);
  • on paws with flange - IM2081 (for AIMM280 - IM2001);
  • without paws with flange - IM3081 (for AIMM, AIU225, 250 and AIMM 280 - IM3011).

Under approval engines can be manufactured with two ends of shaft.

The box of conclusions of AIMM90 engines - 112, AIU90 - 200 has three power clips through passage, AIMM132 engines - 280-six power clips.

Technical datas of engines for the frequency of current of 50 Hz are given in tables 29 and 30.

The adjusting and connecting sizes of engines are given in table 31, 32 and in figures 4, 5.

The adjusting and connecting sizes of VAIU112-200 engines correspond to the sizes of AIU112-200 engines.
