Aiming at the disadvantages of inconvenient installation
easy damage
expensive maintenance and poor anti-electromagnetic interference capability of traditional speed sensor for domestic mining electric motor vehicles
vector control system with AC motor as the traction machine is improved.The high-performance control of speed sensorless vector control system is realized through experiments.The comprehensive data shows that the motor rotating speed smoothly under the condition of speed sensorless closed-loop loading
which can fully meet the needs of mine traction
and provides theoretical guidance and reference for study of speed sensorless vector control of mining electric locomotive.
