Mining electrical locomotives is traction invert control the starting, speed, direction change and braking, which decreased energy consumption, having good electric-saving effect. Invert having shake-proof, damp-proof and dust-proof function, the control loop is controlled by 24V, 0.5A light current, with good safety performance and interlock function when direction change, which avoid damage if driver using anti-vehicle braking. The locomotive with simple construction, low defective rate and easy to maintenance.
1. Constructed in welded steel and suspended by leaf spring or rubber studs on grease bearing seats with tapered roller bearings.
2. In order to achieve continuous and stepless speed regulation, they have an electronic speed controller with high reliability.
3. The AC converters convert the DC from trolley line into AC and the controller adjusts the speed of AC motors by the power frequency of the AC converter.
4. Pneumatic brake to the four wheels by brake shoes. Stop brake by manual mechanical brake.
