Description of specified sizes
Maximum force F
max
Maximum feed force of the motor at maximum current I
max
. Unit [N].
Continuous nominal force F
N
Available continuous nominal force of the motor up to v
N
at nominal current
I
N
. Unit [N].
Maximum current I
max
Maximum current of the motor at F
max
. Unit [A].
Rated current I
N
Rated current of the motor at continuous nominal force F
N
. Unit [A].
Reference voltage intermediate
circuit U
DC
Reference voltage of intermediate circuit for determination of the winding ve‐
locity. Unit [V].
Maximum allowed intermediate
circuit U
DC_max
Maximum allowed intermediate circuit. Unit [V].
Maximum velocity v
Fmax
Maximum velocity at maximum force F
max
. Velocity, up to maximum feed
force of the motor is available. Unit [m/min].
Nominal velocity v
N
Velocity, up to continuous nominal force F
N
of the motor is available. Unit [m/
min].
Force constant K
FN
Relation of force increase to increase of force-creating current. Due to the
principle of an ironless primary part, no saturation effects occur. Therewith,
the constant is not current-dependent. Unit [N/A].
Voltage constant K
EMK
bei 20 °C
Induced motor voltage depending from the travel velocity relating on velocity
1 m/s. Unit[Vs/m].
Winding resistance R
12
at 20 °C
Measured winding resistance among two strands. Unit [Ω].
Winding inductivity L
12
Measured winding inductivity among strand 1 and 2.
This details are typical values, which are determined with a measuring cur‐
rent of 1 mA at a measuring frequency of 1 kHz. Unit [mH].
Winding inductivity L
23/31
Measured winding inductivity among two strands (strand 2/3 or 3/1).
Due to boundary effects, the specified measuring values are different to L
12
.
This details are typical values, which are determined with a measuring cur‐
rent of 1 mA at a measuring frequency of 1 kHz. Unit [mH].
Rated power loss P
VN
Power loss in operation mode S1 (continuous operation) at nominal velocity
v
N
. Unit [W].
Pole width t
P
Distance dimension of pole center to pole center of the magnets on the sec‐
ondary part. Unit [mm].
Thermal time constant T
th
Duration of temperature rise to 63% of the final temperature of the winding at
natural convection and load with continuous nominal force in S1-operation.
