DEVICE FOR REGULATING forced air cooling system of electric locomotive traction motors

摘要

The invention relates to electric rolling stock of railways. Summary of the utility model is that the device for controlling the forced air cooling system traction motor of an electric locomotive, comprising a motor-fan driving motor, which is connected to the power supply through the converter with automatic regulator, moves which through comparison element are connected to a sensor of traction current electric motors and electrical parameters of the sensor motor-fan motor is additionally provided a non-linear functional element of which is connected between the output of the current sensor and the input of the comparison element. The technical result of the claimed utility model is to reduce the power consumption for motor-powered electric fan.
