Megmeet tunnel locomotive inverter protection class IP20

Introduction: MV600Tr is a tunnel locomotive main drive machine, special installation, structure, electrical sealing and other automotive industry-level drive design, suitable for the harsh environment of high temperature, high humidity, vibration and non-ventilation of tunnels. Excellent closed-loop vector control of high-power asynchronous traction motor ensures the smooth control of locomotives starting and stopping at full load and large slopes, and is widely used in the drive control of tunnel locomotives such as subways and mines.
