Of the large number of types of AC electric motors used in modern electrical engineering, the most widespread, convenient and economical is a motor with a rotating magnetic field, based on the use of three-phase current. Thu Read more "
How to start a three-phase asynchronous motor from a single-phase network? The easiest way to start a three-phase motor as a single-phase one is based on connecting its third winding through a phase-shifting device. As such a device can Read more "
3-3. ELECTRIC MOTORS WITH A SHORT-CISED TURN ON A POLE An asynchronous electric motor with a short-circuited turn on a pole is the simplest type of self-starting single-phase electric motor. Its device is shown in Fig. 3-5. Horseshoe stator Read more "
It happens that a three-phase electric motor falls into your hands. It is from such engines that homemade circular saws, emery machines and various types of shredders are made. In general, a good owner knows what can be done with it. But here's the problem, three-phase Read more "
An asynchronous motor is an asynchronous device designed to convert, with minimal losses, alternating current electrical energy into the mechanical energy necessary to start the devices running on this motor. To have more Read more "
Add site to bookmarks The stationary part of the machine, the stator, has a core in the shape of a complete cylinder. A three-phase winding is laid in the grooves on the inside of this core. This winding is switched on under the voltage of a three-phase network, and the current arising in it Read more "
Network voltages and diagrams of the stator windings of an electric motor If, for example, 220/380 V is indicated in the electric motor’s passport, this means that the electric motor can be connected to both a 220 V network (winding connection diagram - triangle) and a 380 V network Read more "
Dear Clients! When our company sells electric motors for various purposes, consumers have a number of questions regarding their operation and possible problems that may arise during operation. On this page we Read more "
Often there is a need in the household or when carrying out repair work to connect a three-phase electric motor to a 220 Volt network. These devices operate on But, as you know, in most homes the supply network has only 220V. TO Read more "
Just before this weekend, my AOL 22-4 asynchronous motor with a power of 400 (W), installed in the drive for switching the on-load tap-changer stages of a power transformer, failed. The reason for its failure was an interturn short circuit of the winding. Such a situ Read more "
