4 Technical data
4.1 Operating behavior
4.1.1 Description of the specified parameters
Maximum energy content
E
max
= energy content at speed n
max
. Unit [kJ].
Rated power
P
N
= nominal power of the storage device at rated speed n
N
. Unit [kW].
Continuous power
P
C
= continuous power output depending on the DC bus voltage. Unit [kW].
Maximum power
P
max
= maximum power output depending on the DC bus voltage. Unit [kW].
Rated current
I
N
= phase current of the energy storage device at rated speed for reaching
the rated power, specified as rms value in ampere [A].
Maximum current
I
max
= maximum briefly allowed phase current that has no damaging effect on
the winding, specified as rms value in ampere [A].
Rated speed
n
N
= working speed defined by the manufacturer. Depending on the applica‐
tion, other speeds are possible (see characteristic curve).
Maximum speed
n
max
= maximum allowed speed of the storage device. The maximum speed
can be limited by mechanical factors, such as centrifugal forces or bearing
wear. Unit [min

= thermal time constant for Rexroth temperature model. For further notes
on the temperature model, refer to the Rexroth IndraDrive MPx application
manual
Discharge capacity
C
ab
= capacitance of short-circuited power connections U, V, W against the
housing. Unit: [nF].
Number of pole pairs
p = number of pole pairs of the storage device.
Power wire cross-section A
Unit: [mm²]. Rated for cables by current carrying capacity according to VDE
0298-4 and laying type B2 according to EN 60204-1 at a surrounding air tem‐
perature of 40 °C. Other installation methods or higher ambient temperatures
may require a higher power wire cross-section.
