Silicon carbide (SiC) technology power electronics provides high switching frequencies without current derating and makes additional motor chokes obsolete. An integrated control unit that uses Field Programmable Gate Array (FPGA) technology carries out all control tasks with a control frequency of up to 192 kHz. The AVL SPECTRA E-Motor Dynos are equipped with oil-lubricated bearings and hybrid cooling technology. High precision bearings reduce vibrations to extremely low levels. The combination of AVL SPECTRA converter and dyno form a highly capable load system covering test requirements with the highest rotational speeds as well as delivering high torque and power.

Superior Control
The ultra-fast 1MHz control cycle reduces dead times and enables the execution of highly dynamic test cases. In addition, the minimized current ripple reduces the occurrence of dyno torque ripple.
High Switching Frequency Without Derating
SiC power electronics are capable of high switching frequencies without the drawback of current derating and make additional motor chokes obsolete.
High-precision Bearing Technology
Highly precise and oil-greased bearings keep vibration levels to a minimum and ensure maximized bearing lifetime over the whole operating range.
