Beschreibung
Zusammenfassung:	An electromagnetic power drive for a friction welding machine, comprising a magnetic core installed immovably, which carries a power coil connected to a voltage regulator made as a switch and at least one pickup coil connected to an integrator producing voltage proportional to the actual value of the magnetic flux during friction welding, which is connected to a comparison means comprising two comparators, a driving input of one of said comparators receives voltage proportional to the assigned value of the magnetic flux during friction welding, the driving input of the other comparator receives voltage proportional to the other assigned value of the magnetic flux, and a control signal generator having a hysteresis-loop output characteristic, which is connected to the comparators, the output of said generator being the output of the comparison means electrically coupled with the voltage regulator.
