powerMELA Drives and Generators

  • High continuous output
  • Compact construction through integrated power electronics
  • Simple scaling and network capability thanks to protective insulation
  • Motor and generator operation
  • Robust, proven and field-tested

The powerMELA E machines are permanently excited synchronous machines which provide a compact construction thanks to the integrated inverter. Optionally combined with a transmission and designed for high continuous output thanks to oil cooling, they are specially designed as generators or main and auxiliary drives for use in mobile machines.

The machines are designed for four-quadrant operation and can be operated via the CAN bus with nominal values for torque, voltage and speed regulation.

Thanks to the integrated inverter, a DC voltage connection suffices for the powerMELA E-machines. Complex wiring is obsolete; space and weight are saved and a high, unsurpassed power density is achieved.

In order to supply constant high power, thermal losses must be dissipated directly after their generation. Even a particularly high degree of efficiency of 97% causes thermal losses of several kilowatts. Only the environmentally-friendly powerMELA oil cooling permits the direct cooling of energized components inside the machine.

As a result of the necessary high electrical output power, either current or voltage or both need to be adapted accordingly. powerMELA prioritizes an increase in voltage, because an operating voltage of up to 800 volts and reduced cable cross-sections ensures performance-capable networks with limited effort.

There is a special protective insulation construction design, the powerMELA, for both high voltages and also for interference suppression of the network, which ensures reliability and fault-free operation.
