Asynchronous three-phase DC electric motors with general industrial design include the widely used AIR 63 series, which is produced in 6 modifications: AIR 63A2, AIR 63 A4, AIR 63B2, AIR 63B4, AIR 63A6 and AIR 63B6. They differ in rotation speed, the version of the core length and power. They are used in various devices used in the national economy and everyday life to convert electrical energy into mechanical energy. Lifting cranes, elevators, conveyors, winches, pumps are far from an incomplete list of equipment where the AIR 63 series is used, without which the operation of such equipment is impossible.
The main parts of the engine are as follows:
- housing (made of aluminum alloy or grey cast iron);
- stator (the winding is made of enameled copper wire);
- rotor (made of aluminum or aluminum alloys);
- bearing shields (cast iron);
- fan (for cooling);
- the control device.
Principle of operation - the principle of electromagnetic interaction arising between a stationary stator and a rotating rotor is used.
The method of attaching the engine to the devices can be:
- on paws - IM1081(1001);
- on the paws and with a flange - IM2081(2001);
- without paws and with a flange - IMZ081(3001).
This allows the electric motor to be mounted in any spatial position – horizontally, vertically, to the ceiling.
Engine marking and its decoding:
- A – asynchronous;
- And – development of Interelectro;
- P is the binding of the engine power to its connecting (installation) dimensions, according to the requirements of RS3031-71;
- 63 – the height of the axis of rotation in mm;
- A2 is the length of the core (A) and the number of poles of the magnetic field (2), the engine speed is 3000 rpm. ;
- A4 is the length of the core (A) and the number of poles (4), the engine speed is 1500 rpm.;
- A6 is the length of the core (A) and the number of poles (6), the engine speed is 1000 rpm.;
- B2 is the length of the core (B) and the number of poles (2), the engine speed is 3000 rpm.;
- B4 is the length of the core (B) and the number of poles (4), the engine speed is 1500 rpm.;
- B6 is the length of the core (B) and the number of poles (6), the engine speed is 1000 rpm.
The supply voltage is 220/380 V from an AC network with a frequency of 50 Hz. When buying, it is possible to order the manufacture of an engine on a special order for power supply from an electric network with a frequency of 60 Hz.
The degree of protection of the product is IP55, which allows it to be used in conditions of high humidity and dust. The operating mode is continuous.
