Analog three phase EPU1M

DC three-phase electric drives (EPU1M) replace electric drives EPU, BTU, ETU, BUV, ShUV and their analogs.

The electric drives are produced in two modifications:

1) Feed electric drives EPU1M-2…П, ПЭ - reversible, for high-torque motors. They secure torque overload no greater than 6 for the electric drives of 25, 50 and 200 A and no greater than 4 for electric drives of 100 A; their speed control range is up to 10000 and they are intended for reversible quick response widely controlled drives with single-zoned speed regulation, including NC machine fee motion, industrial manipulators and other machinery.

2) Principal motion electric drives for reversible and non-reversible widely controlled drives of capacity 1,5-250 kW with double-zoned and single-zoned speed control, including NC machines principal motion machinery and other equipment.

Principal motion electric drivessecure current overload no greater than 2 and, depending on the control type (armature, motor field, feed-back and motor speed control range) are subdivided into:

  • EPU1M...E- single-zoned (armature control), with reactance voltage feed-back and speed control range up to 20;
  • EPU1M...M - single-zoned with motor speed feed-back and speed control range up to 1000;
  • EPU1M...D - double-zoned with motor speed feed-back and speed control range up to 1000.

Electric drives EPU1M provide operation with the following DC electric drives: PBV, 2PBV, 2PKV, DPU, DR, 4P, 2P, PB2P, PO2P and others; they are powered by mains of voltage 220, 380, 400, 415 V (frequency 50 Hz) and 220, 230, 380, 400, 415, 440 V (frequency 60 Hz), therewith the power part is connected to the mains by a power transformer or a network reactor (current-limiting or switching).

Electric drives EPU1M are equipped with: free-from-tuning system of pulse-phase control (СИФУ), expanded test operation, current controller in the electric drive structure, simplified linearization in an intermittent duty mode, etc.

The basis of the power circuit EPU1M is a three-phase bridge circuit, produced:

  • at power thyristor modules with application of pulse transformer units — for control units of nominal current 25, 50, 100 A;
  • at wafer thyristor with application of pulse transformer units — for control units of current 80, 200, 400 and 630 A.
