User’s Manual for Advanced Axial Flux Synchronous Motors and Generators

*EMRAX 268 VHML Low Voltage version always has 2 sequences of phase connectors (2x UVW).
**Controller for EMRAX 268 Low Voltage motor should have very high peak and continuous motor current (1000 Arms peak and 500 Arms continuous). It is
difficult to find such a high current controller in the global market. The most suitable is emDrive 500 from the Emsiso Company, which has 500 Arms continuous
and 800 Arms peak motor current. Another possibility to get a high enough motor current is to connect 1 motor with 2 controllers by using 2 set of phase
connectors (2x UWV) on the motor.
Graphs valid for EMRAX 268 High Voltage Combined Cooled (CC):
Graphs were made from tests, which were made by Letrika d.d. in 2014. The motor was tested only up to 400 Nm of torque,
because the opposite generator on the test bench generated only 400 Nm of torque. DC voltage from the batteries was only 400
V, so we were able to run the EMRAX motor only at lower speed than the maximal motor speed. The motor was also tested with
magnet field weakening setting in the controller – in this case we achieve significantly higher speed at the same power.
Water/glycol flow was only 3,5 l/min, but it must be 6-8 l/min as it is written in the Technical Data Table.
