Operation of the single-phase electric motor 220B, description of technical data of single-phase electric motor

August 17, 2020

Single-phase electric motor 220V is a product, having power in section 0,18-3,0 kw. This mechanism is equipped with one phase, which feeds the device from the mains. The use of a single-phase device is necessary for household use, and industrial purposes. Usually this mechanism is mounted in various electrical appliances.

Varieties of electric motors

There is a huge variety of electric motors. Among them it is customary to distinguish such species:

  1. General purpose devices. They are used in industrial production and in large premises. They are protected from possible oxidation and explosive impurities.
  2. Electromechanisms with direct and alternating current. DC devices are powered by a rechargeable battery or other DC power source. AC motors need only an AC source for power.
  3. Devices with synchronous and asynchronous rotor. The synchronous motor rotates on the frequency of the magnetic field, and asynchronous on the contrary.
  4. Electric motors with single-phase, two-phase and three-phase network. Single-phase device is powered by a single-phase network, two-phase from a network with two phases, and three-phase from a network with three phases.
  5. Devices with short-circuited or phase rotors. In the absence of large starting torques, short-circuited rotors are used. In those cases, when the mechanism experiences increased power loads, the use of phase rotors is shown.

The difference between the engines is determined by some parameters:

  • installation execution;
  • climatic performance;
  • modification;
  • number of speeds.

Devices with one phase are used as in household, and for industrial purposes. They are placed in different mechanisms. They work from the AC mains 220 V. The single-phase mechanism has a built-in capacitor of small size.

To increase the starting current, the electric motor is completed with the regulating device, consisting of two condensable containers: starting and working. In addition to these details, the control unit is equipped with a relay for starting and a relay for current protection. As a result of operation of the equipment there is a start by the regulating block of starting capacity in the mode of start of the engine or in the presence of restart.

This type of electric motor is used to drive such mechanisms, as: joinery machines, electric pumps, compressor devices, industrial ventilation units, conveyors, lifts, cormorants, concrete mixers and other devices.

A double winding is mounted in the stator device. This is necessary for the proper operation of the condensing tank. So that the capacitor capacitor is not exposed to the atmosphere, it is placed in place, protected from temperature changes. in addition, operating the electric motor, you need to monitor the size of the condensable container.

Technical data of single-phase electric motors

Electric drives with one phase are available in the following version:

  • paws "IM1001";
  • flange "IM3001";
  • combining "IM2001".

Devices can be equipped with climatic design: "AT 2", "U3", UHL4. Electric motors with one phase 220V are available with low power. Additional description of single-phase motors is presented in the table below on the example of the electric motor brand "AIRE".

Single-phase electric motors of the AIR 220B brand are completed for the drive of various household appliances. They operate from mains voltage 220 V. Device design, already has in the complete set condensers. The single-phase mechanism according to the assembly scheme is connected and can be put into operation at once. The designation "AIRE" is defined as a single-phase motor, having two windings and a capacitor capacitor.

Engine operation 220 In due to the following conditions:

  • 220V power supply and frequency 50 Hz;
  • in operating mode "S1";
  • IP 54 protection;
  • cooling "IC 041";
  • heat resistance class of insulation "B or F" according to GOST 8865-93;
  • climatic factors according to GOST 15150-69 or Guest 15543.1-89.
  • the density of dust in the section to 2 mg of 1 m3;
  • mechanical design "M1" according to Dst 17516.1-90;
  • vibration loads on electric motors of the 1st degree of rigidity according to GOST 17516.1-90.

Single-phase electric drives are in great demand among a wide range of consumers. After all, they work perfectly from the 220V network. The device is presented in a compact design, thanks to which it is conveniently operated and is capable to save the consumed electric power. The load on the meter is almost always minimal. Surprises single-phase electric motor and its simple principle of operation. It is not necessary to have qualification skills and special tools to connect it. Repair of such devices is quite primitive. But to minimize damage to the device, it is better to choose devices of proven brands.
