Series DC Motors 4PF from the Russian manufacturer OOO Elektroprom, they are used in a wide range of different industries under the guidance of regulated converters. Independent excitation, power supply is carried out by means of appropriate generators or through rectifiers. A variety of mounting configurations are available in horizontal and vertical positions.
All motors are equipped with tachogenerators and control sensors to protect sensitive elements from overheating. The cooling system has an independent power supply, forced blowing, end position (opposite to the shaft) or on the side surface. The stator design has a stacked structure, a compensation winding is used to reduce the formation of a harmful magnetic flux of the armature. The electric motor is designed for continuous operation, and operation in cycles S2-S8 is also allowed.
Encoders can also be additionally installed on request.
