This motor was designed by Trans Vaal Electric for a coal mining company to replace its ageing fleet of 46kW hydraulic pump motors.

The new motor requires no mechanical or electrical modification of the machine for fitting and has now been adopted as the standard component for the hydraulic pump drive on the continuous miner.

Since the introduction of this motor the number of failures of the hydraulic system relating to motor fault have decreased significantly, improving the availability of the continuous miner and consequently the production levels.
