- Country of manufactureUkraine
Engines asynchronous explosion-proof with a short-circuited rotor are intended for work from a network of three-phase alternating current, with a frequency of 50 Hz and 60 Hz for the drive of stationary cars in explosive productions coal (AIU, VAIU engines), to chemical, gas, oil-processing industry (AIM, AIMM engines).
Engines are manufactured for deliveries to the countries with moderated (with a type of a climatic modification of U2, 5) and tropical (with a type of a climatic modification of T2, 5) climate. AIM90, AIMM 90 - 280 engines have also execution of OM2, B5 (for sea vessels).
The adjusting and connecting sizes of engines are given in table 3.
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:

AIU90-200, 2AIU225-250, VAIU112-200 series - 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. A class of heat stability of isolation of F engines (VAIU engines - a class "H"). Series engines, 2AIU225,250, AIMM280-1 are manufactured with a winding of rigid coils.
Engines are manufactured the following executions on a way of installation in accordance with GOST 2479:
- on paws - IM1081 (for AIMM280 - IM1001);
- on paws with a flange - IM2081 (for AIMM280 - IM2001);
- without paws with a flange - IM3081 (for AIMM, AIU225, 250 and AIMM 280 - IM3011).
In coordination engines can be manufactured with two ends of a shaft.
The box of conclusions of AIMM90 engines - 112, AIU90 - 200 has three power clips through passage, AIMM132 engines - 280, AIU225,250 - six power clips.
AIUL engines asynchronous explosion-proof with a short-circuited rotor are intended for work from a network of three-phase alternating current, with a frequency of 50 Hz for the drive of mine LV-25, LVU-25 winches in explosive productions of the coal industry.
Type of a climatic modification of U2,5; T2,5.
