Peak current I
max
[Arms]
Sinusoidal peak current RMS value. The configured peak current of
the servo drive used must be less or equal.
Force constant k
F
[N/Arms]
Indication of how much force the motor generates per ampere with
the standstill current. The following applies: F
0
= I
0
x k
F.
Voltage constant k
E
[Vrms/kmin-1]
Indication of the induced motor EMF at 20 °C, based on 1000 rpm.
This is specified as the sine RMS value between two terminals.
Rotor moment of inertia J [kgcm²]
Measure of the acceleration capacity of the electric cylinder.
Release delay time of brake t
BRH
[ms]
Specification of the response times of the holding brake [+] when
operated with the nominal voltage.
Winding inductance L [mH]
Indication of the motor inductance. It is the average value for one
motor revolution, with two energized phases, at 1 kHz. Saturation of
the electric cylinder must be taken into account.
Spindle pitch p [mm]
Pitch of the spindle used. One revolution corresponds to a linear
movement in the amount of the spindle pitch.
Mechanical efficiency η [%]
Summary of all mechanical losses in the electric cylinder. This can
be higher under certain circumstances and is variable to a small ex-
tent over the useful life.
Dynamic load rating C
dvn
[kN]
The axial force that a ball screw can theoretically support with a
nominal life of 10
6
revolutions.
Heat input Q [W]
Proportion of the maximum power loss that is dissipated via the con-
nection surface.
Temperature flange surface u [°C]
Maximum temperature of the flange surface when heat input Q is
applied.
