Drives and generator
In addition to the powerMELA.c80 motor, we offer the powerMELA.c140 motor which is larger and heavier and generates more power. Like all powerMELA components, the motors are also characterized by their field-tested robustness.
TECHNOLOGIES
The powerMELA.c140 motor is a permanently excited synchronous motor with a nominal voltage of 650 VDC. The power electronics are integrated together with the oil cooling into an IP6K9K housing.
Integrated power electronics
Due to the integrated inverter, a DC voltage connection is sufficient for powerMELA electric machines. Complex wiring is no longer required, which saves space and weight, and an incomparably high performance density is achieved.
Operating voltage
Due to the high electrical power of 140 kW required, it is necessary to invest accordingly in current or voltage. The powerMELA motors favor the increase in voltage, as a nominal operating voltage of max. 800 V and reduced cable cross-sections ensure high-capacity networks with limited costs. In this way, ohmic losses due to high currents are prevented.
Protective insulation
The powerMELA motors feature the special concept of a protective insulation structure both for high voltages and for interference suppression on the network, which ensures safety and interference-free operation when using smaller interference suppression capacitors.
Cooling concept
For a consistently high power output, heat losses must be dissipated immediately after their generation. Even a particularly high degree of efficiency of 95 % causes heat losses of several kilowatts. Only the environmentally-friendly powerMELA oil cooling permits the direct cooling of live components inside the machine.
Software
The comprehensive software toolchain for the powerMELA C140 assists you with system integration.
