Graphs valid for EMRAX High Voltage Combined Cooled (CC) motor type:
Graphs of the EMRAX 208 Medium and Low voltage motor type:
Graphs of EMRAX 208 Low Voltage and EMRAX 208 Medium Voltage are similar to graphs of EMRAX 208 High Voltage. The only
differences are the DC voltage and motor current. These two parameters can be read from the Technical data table for the
EMRAX 208 Low and Medium Voltage motor.
Low Voltage motor needs 4 x higher motor current and 4 x lower DC voltage for the same power/torque and RPM, compared to
EMRAX 208 High Voltage motor.
Medium Voltage motor needs 1.52 x higher motor current and 1/3 lower DC voltage for the same power/torque and RPM,
compared to EMRAX 208 High Voltage motor.
Graphs of the EMRAX 208 Liquid cooled (LC) and EMRAX 208 Air Cooled (CC):
Continuous power of the liquid cooled or air cooled motor is 20% lower than continuous power of the combined cooled motor.
The peak power is the same. Data is presented in the Technical Data Table.
