Kretzschmar motor Germany Kretzschmar model Kretzschmar price

Kretzschmar motors are devices that place the rotor in a rotating magnetic field, where it obtains torque under the action of the field, causing the rotor to turn. The rotor is a rotatable conductor, typically squirrel-cage in shape. Invented by electrical engineer Nikola Tesla in 1887. The rotor is a rotatable conductor, typically squirrel-cage in shape. The stator is the non-rotating part of the electric motor, with the main task of generating a rotating magnetic field. The rotating magnetic field is not achieved by mechanical means. Instead, alternating current is applied to several pairs of electromagnets, causing their magnetic pole properties to cycle.
