General industrial electric motors of series 2AИР by DIN standart

Description

General industrial purpose asynchronous electric motors with square-cage rotor of 2AИР series are designed for operation from a three-phase alternating current network, with frequency 50 Hz and 60 Hz, with voltage from 220 to 660 V.

The line of this series of general industrial purpose motors consists of 56, 63, 71, 80, 90, 100, 112, 132, 160, 180, 200, 225, 250, 280, 315, 355, 400 and 450 standard sizes, with the quality of poles 2, 4, 6, 8 and 10.

General industrial electric motors 2AИР are produced with the following energy efficiency classes:

  • IE1
  • IE2
  • IE3

In IEC 60034-30-1 there are such classes of energy efficiency for asynchronous electric motors (IE=International Efficiency):

  • IE1 (Standard Efficiency)
  • IE2 (High Efficiency)
  • IE3 (Premium Efficiency)
  • IE4 (Super Premium Efficiency)

Linkage dimensions and technical features of the electric motors are indicated in the catalogue.

2AИР motors are produced with the connection of powers to standard sizes according to DIN 42673 and DIN 42677 (CENELEC).

The motors are designed for operation at S1 mode.

The engines are manufactured in cast-iron case, have the level of protection IP55.

The engines are equipped with PTC thermistors (with positive coefficient of resistance) for protection the stator from overheating or РТ-100 sensors could be installed for protection of the stator and bearing units from overheating (this option is ordered by a customer).

The electric motors have an insulation system of class of heat resistance F (thermal index is 155°C). With a customer’s agreement the electric motors could be produced with class of heat resistance H.

General industrial electric motors are manufactured in the following versions according to the installation method:

– on the paws – IM1081 (В3) for engines up to 250 dimensions inclusive, IM1001 (В3) for engines from 280 dimensions inclusive;

– on legs with a flange – IM2081 (B35) for engines up to 250 dimensions inclusive, IM2001 (B35) for engines from 280 dimensions inclusive;

– without paws with a flange – IM3081 (B5) for engines up to 250 dimensions inclusive, IM3001 (B5) for engines from 280 dimensions inclusive.

More detailed information about a method of mounting is indicated in the catalogue.

The engines allow both right and left rotation directions. The direction of rotation must be changed only from the rest position of the rotor.

With the manufacturer’s agreement, electric motors with power from frequency-controlled converters can be manufactured (for this purpose it’s needed to fill the data sheet).
