Unit: KSP - 6B Controller Purpose: Regulating the voltage on Electric traction Engines' clamps, as well as their excitement level. Composition: 18 contactors and leads. The system is developed by Professor L. M. Reshetov. The unit has 20 working positions.
Subsequent positions (3 to 16)
The voltage on motor clamps is increased, due to the serial connection of load to the traction coil output.
Position 17: The excitement level is brought down to 53.5%. Position 18: The same working mode as position 17. Position 19: The excitement level is brought down to 32%.
The main controller is controlled by Engineer's controller (1KU - 023). The unit has two handles. They are: Reversive - features Reverse, Drive, and Neutral positions. Main - features neutral, maneuvering, and 4 working positions.
Traction engines and most of electrical devices are manufactured by the Electric Equipment plant of Riga.
Unit: Phase Splitters Placed: Under the body of Motor cars. Purpose: Converts single phase 220 V Current into 3 phase. The produced current serves for powering various supplementary machines.
Unit: Fan wheel. Placed: On splitter's rotor(?). Purpose: Cooling rectifiers, reactors, and transformers. The rotational frequency of the splitter is 1495 rpm.
Unit: Motor - Compressor. Composition: LOSV-72-6 Electric Motor, with EK1-V or EK-1P compressor. Performance 0.7, 0.6 and m3/min. Location: Under the body of attached and cab cars.
Unit: Alkaline, accumulator battery (90KN-55) Normal Voltage: 110 V. Charged by 220 V coil of the transformer, through silicon rectifier. The stabilized is in use for supporting the voltage. Location: Under the body of attached and cab cars.
The construction speed of the trainset is 130 km/h. Calculated acceleration up to 60 km /h is 0.8 m/s^2.
