In the following, parameters and characteristic curves of the IndraDyn A
series and specifications of the motor data sheet are explained.
Parameters
Available torque that can be output at the rated speed in operating mode
N
S1 (continuous operation). Unit = Newton meters (Nm).
Mechanical power output of the motor while running at the rated speed
N
and rated torque. Unit = kilowatts (kW).
Phase current of the motor while running at the rated speed and rated
N
torque, specified as a root-mean-squared value in amps (A).
Typical working speed defined by the manufacturer. Depending on the
N
particular application, other working speeds are possible (see speed-
torque curve).
Maximum torque that can be output at peak current I
max
meters (Nm).
⇒ The maximum torque that can be attained depends on the drive
control device used. Only the specified maximum torque M
selection lists is binding.
Maximum power output of the motor at 540V
max
⇒ The maximum output that can be attained depends on the drive
controller that is used and on the power supply. Only the maximum
output specified in the selection data is binding.
Maximum short-term branch current of the motor permitted without
max
damaging the winding, given as a root-mean-square value in amperes
(A).
⇒ To avoid a thermal overload when operating the motor with external
controllers, note that the current is to be reduced after 400 ms to 2.2x
the rated current and that I
temperature is in the permitted range if the degree of relief of the
motor permits this.
The maximum permissible speed of the motor in (min
max
on the bearing type according to type code. Usually, the maximum speed
is limited by mechanical factors as e.g. centrifugal forces, bearing strain,
or use of a holding brake.
Ratio of torque increase to motor torque-forming current. Unit = Nm/A.

Rated for cable assemblies with current carrying capacity according to
VDE0298-4 (1992) and installation type B2 according to EN 60204-1
(1993) at 40°C ambient temperature. The power wire cross section in
2
(mm
) can deviate depending on the selected type of connection - plug or
terminal box. Therefore, when selecting the appropriate power cable, pay
attention to the information in Chapter 8 "Connection Techniques" and to
the documentation "Rexroth Connection Cable" (MNR R911282688).
