Direct current electric motors Domestic electric motors 4PFM (Belgorod Electrotechnical Plant)

Modified series of DC motors 4PFM productions Belgorod Electrotechnical Plant designed in accordance with current standards, the overall height of the axle is presented in four sizes, a version with a built-in tachogenerator is always available, a wide selection and high-quality performance. They are designed for operation in continuous operation mode (S1) under the conditions of compliance with the nominal values of the armature current, cyclic modes S2 – S8 are permissible (classification GOST 183-74).

The control of the shaft rotation speed to the nominal limits is carried out by controlling the level of the conducted voltage, above the excitation current. The stability of the system with independent excitation is provided by the control circuit, the direction with the possibility of reverse.
