  Electric power tools 36V 200Hz was commonplace in Soviet era factories. It typically operated from a 380V 50 Hz - 36V 200Hz machine converter. The converter consisted of an electric motor and a generator on a common shaft. This allowed for low, safe voltage, galvanic isolation, and the absence of friction parts like coal brushes in the collector motor.

  This is 100% intended for a factory, spinning up, running in 15 screws in a row, and only really being engaged when pushed in.

  This is a replacement for an industrial pneumatic tool. And in the front part there is not a hammer, but a clutch and torque limiter. Therefore, the switch is locked in the on position. The tip of the screwdriver with guides, which is missing here, is pressed against the screw head, the clutch engages, the screw is tightened, and the clutch begins to slip.

  I&apos;m blown away by how helpful the comments are. I now know this thing runs on manually-converted (ie a motor from the mains directly spinning a generator)old soviet 380V 50Hz 3-phase to 36V 200Hz 3-phase, to power clutched electric screwdrivers to a set torque for industrial assembly.<br><br>Man, the internet is cool

  i know nothing, but at <a href="https://www.youtube.com/watch?v=zAFfbsQULFE&amp;t=1130">18:50</a> when you realized that it only spins when the bit is pushed in, it reminded me of seeing modern factory videos where they need to screw in 20 different screws on some component and they do it quickly. in those situations, i imagine it&apos;s very handy to have the bit stop spinning as soon they pull off, even if the motor is still spinning, so they don&apos;t over torque the screw or strip the head as they pull away from it.

  As Russian I like that you worked drunk. It is exactly how the tool was designed, built, and used.

  The symmetric plug means you could swap two phases by flipping the plug over thus reversing the direction!

  So this was an industrial factory tool. Nowhere else on planet earth you will find 36V 200Hz 3 Phase.<br>In central europe 200V 300Hz 3 Phase used to be a thing but I havent come accross that in the wild at all. Its an obsolete system.

  36 вольт в СССР считалось безопасным напряжением для работ на проводящем полу. 200Гц позволяют уменьшить габариты инструмента и сделать его непригодным для использования дома (в СССР было принято все воровать с работы)

  That was awesome. As a Russian I appreciate the random Russian words you&apos;ve learned, and the pronunciation isn&apos;t half bad!
