ELECTRIC MOTORS/ GENERATORS

the powerMELA E-machines are permanent magnet-based synchronous electric machines which, with their integrated inverter, form a very compact design, which facilitates easier installation. They were developed specifically for mobile work machines for use as both primary power source and as secondary for various auxiliary systems. As an option, they can be combined with a power transmission and are designed for high, continuous power outputs, both as motor and generator.

 

ELECTRIC POWER

Thanks to the integrated inverter, only one DC connection to the powerMELA E-machines is needed. Complicated cable routing is eliminated, thus saving space and weight while achieving unmatched power density. In order to deliver constant high power, thermal losses must be absorbed directly when and there they occur. Even with an extremely high efficiency of 97%, heat corresponding to several kilowatts is in fact also generated in an electric machine. This is handled by direct oil cooling of the relevant components inside the powerMELA E.

As a result of the necessary high electrical power output, either power or voltage or both need to be adjusted. powerMELA works with a working voltage of up to 800 volts, which provides advantages with a smaller cross-sectional area in cabling that facilitates installation in the mobile machine. There is also a special insulation protection so that the working voltage is safely managed, and that interference is suppressed. This ensures a reliable and error-free operation.

Electric power supports mobile work machines on the road towards E-mobility and "green" sustainable machines. This can be done either via hybrid systems or via fully electric machines. Read on below what powerMELA E-machines can offer you.

POWERMELA C SERIES

The powerMELA C series is a family of permanent magnet based, synchronous electric machines with an integrated inverter. They were developed specifically for mobile work machines for use as both a primary power source and as a secondary for various auxiliary systems. The electric machines are liquid-cooled and designed for four-quadrant use. The desired torque, voltage and speed values ​​can be set over the CAN bus. The very same unit can be used as either motor or generator.
