Buy electric motors AIR132M8. Air engine decoding

The AIR electric motor is a key link in the mechanism, ensuring its performance. Depending on what characteristics the engine offers, the entire device as a whole will act in the same way. Electric motors cover all spheres of human activity, first of all, they are widely in demand in industry.

A synchronous electric motor is an alternating current device. The rotation frequency of the magnetic field that the armature creates is equal to the rotation frequency of the rotor.

The AIR asynchronous electric motor is a device that operates using alternating current, converting electrical energy into mechanical energy. In this device, the rotor rotation frequency is not equal to the rotation frequency of the magnetic field. Uninterrupted and reliable operation of an asynchronous motor is ensured by compliance with the necessary conditions: the altitude above sea level at which the motor operates should not exceed 1000 m; ambient temperature varies from -40 to +40 C; relative air humidity should not exceed 90% (at a temperature of +25 C), air dust content for closed engines is less than 10 mg/m3, 2 mg/m3 for protected ones.

For non-standard conditions, special engines are produced.

Explosion-proof asynchronous electric motors eliminate the possibility of explosion by enclosing the motor components that directly interact with electricity in an explosion-proof enclosure. Such a shell withstands the pressure of the explosion inside, preventing it from escaping into the environment.

AIR marking

A general view of the marking is shown in the figure next to it.

Let's consider each element sequentially.

• AIR
  is an abbreviation, the decoding is indicated in the picture and does not require additional description;
• Heights of rotation
  - h indicator shown on the size chart;
• Installation dimensions
  - dimensions along the length of the housing (S - small, M - medium, L - large) + sometimes an additional symbol along the length of the shaft core (A or B). A detailed correspondence of codes to the dimensions of each specific model is presented in the document attached to the article “Installation dimensions (overall and connecting) AIR.pdf”;
• The number of poles
  are specific numbers, which from a practical point of view mainly show the synchronous speed of rotation of the magnetic field, which is also related to the frequency of the electrical network. The more poles, the lower the efficiency and power factor, as well as the lower the speed. For the equipment in question, the correspondence is as follows:

• 2 pole pairs = 3000 rpm;
• 4 pairs = 1500 rpm;
• 6 pairs = 1000 rpm;
• 8 pairs = 750 rpm;

Mounting design

Let's look at each number separately.

• The first number
  is the mounting method:

• IM 10XX - paws;
• IM 20XX - combined (feet/flange);
• IM 30XX - flange;

• With one shaft end - 1;
• With two shaft ends - 2;

• The third number
  is determined by the location of the engine and the direction of the shaft axis.
  Below is a table showing the possible options, but there is also a special meaning - “ 8
  ”, meaning universal execution, i.e. The motor can be positioned in any direction of the shaft axis!

The table is also attached as a file to the article for more careful study, if necessary.

General industrial electric motors AIR series

Electric motors of the AIR series are used in the industrial sector to convert electrical energy into mechanical energy. The operating principle is based on electromagnetic induction. Various modifications of three-phase asynchronous motors have a very wide scope of application:

• mechanical engineering and machine tool industries;
• agricultural equipment;
• woodworking;
• pumping and ventilation equipment;
• lifts and conveyor belts.

The special purpose that electric motors of the AIR series may have is indicated in additional designations. Abbreviations indicate recommendations on operating conditions that affect the design features of fasteners, the presence of manual braking adjustment, installation dimensions that are close to absolute accuracy, the level of chemical protection, etc. It is worth considering that special-purpose mechanisms may have an increased level of performance (including and sound effects).

Depending on the purpose, asynchronous electric motors can correspond to one of the types of climatic modification: U2; U3; T2; UHL4. Asynchronous electric motors are produced with design differences that determine the degree of protection (IP55; IP54) in versions with stationary and rotating magnetic fields based on operation in conditions s1.

The degree of protection of the engine from contact with moving parts, conductive elements and from the penetration of foreign objects or moisture into the engine can affect the design features of the protective casing. There are completely open motors that are operated in special rooms without exposure to extraneous factors (including the presence of people during operation), protected by a current-insulating casing and equipped from drops of moisture (strictly vertical direction of flow). The highest degree of protection is to protect a special-purpose mechanism from dust by installing a dust-proof membrane under the outer casing.

AIR - motors with a squirrel-cage rotor type are distinguished by their relative simplicity of design. Stationary contacts ensure reliability during operation. According to the installation method, electric motors of the AIR series are divided into units for vertical/horizontal or built-in installation. Each type of fastening is indicated by corresponding markings on the electric motor itself.

For horizontal installation:

• M101 - on feet to the frame.
• M201 - for suspended mounting on a frame.
• M301 - motor with an annular flange for installation on a bearing shield.

For vertical installation:

• M302 - motor for mounting with a flange on a bearing shield with the working end of the shaft in a “down” position; M202 - modification for flange mounting on a panel (+ paws on the frame); M203 - similar to M202 only with an “up” operating position.
• M303 - a modification of the fastening similar to M302 with fastening the working end of the shaft “up”. M102 - mounting option M303 with foot mounting; M103 - identical fastener M102 with the working end in the “up” position.

Decoding the symbols of AIR engines

• “A” - asynchronous motor type.
• “I” is the degree of protection from external factors.
• “P” is the relationship between engine power and installation dimensions.
• Digital indicators indicate the height of rotation of the axis.
• “S” is the size of the installation according to the length of the frame.
• The next numerical designation is the number of poles.
• “U” - climatic version.
• “Z” – category of electric motor placement.

Main technical characteristics of electric motors of the AIR series

Power and installation dimensions (from the base platform to the center of the shaft) are determined by GOST 51689-2000. The resistance of the insulation to heat must comply with the requirements of GOST 8865-93 (class “F”). The level of noise generation (in idle mode) is class 2 according to GOST 16372-93.
