10.2 Combinations PMC-2 and SB-motors
Definitions
M
OM
[Nm] Standstill torque of the motor
Constant torque (100% ED) with speed n
0
. With an ambient temperature of
40°C, an excess temperature of 60°C on the motor case in dependence of the
thermal motor time constant will appear.
M
NM
[Nm] Nominal torque of the motor
Constant torque (100% ED) with nominal speed n
N
. It is smaller than M
0
as a
result of the speed-dependant losses. With an ambient temperature of 40°C,
an excess temperature of 60°C on the motor case in dependence of the
thermal motor time constant will appear.
M
OD
[Nm] Standstill torque of the drive
Constant torque (100% ED) with speed n
0
. With an ambient temperature of
40°C, an excess temperature of 60°C on the motor case in dependence of the
thermal motor time constant will appear.
M
ND
[Nm] Nominal torque of the drive
Constant torque (100% ED) with nominal speed n
N
. It is smaller than M
0
as a
result of the speed-dependant losses. With an ambient temperature of 40°C,
an excess temperature of 60°C on the motor case in dependence of the
thermal motor time constant will appear.
M
SD
[Nm] Peak torque of the drive (motor in combination with PMC-2)
I
NC
[A] Rated current of PMC-2
Controller rated current (continuous operation S1).
I
SC
[A] Peak current of the PMC-2
Peak current of controller for acceleration procedures. At the same time
effective value for motor current at peak torque M
SD
that is provided by the
drive combination for a short term.
P4.02 [A] Parameter value "max_current“ for the combination motor - PMC-2.
P4.08 [A] Parameter value "nom_current“ for the combination motor - PMC-2.
n
NM
[1/min] Nominal speed of the motor
Usable speed at nominal torque. The idle running speed n
L
and the maximum
mechanical limit speed n
Limit
of the servo motor are higher.
R
W100
[Ω] Resistance of a motor winding
Resistance of a motor winding between a phase and neutral point with an
ambient temperature of 100°C.
K
M100
[Nm/A] Torque constant of the motor (at 100°C motor temperature)
Ratio of standstill torque M
0
and standstill current I
0M
.
J
M
[kgcm
2
] Moment of inertia
The motor's moment of inertia refers to a motor with resolver, but without
brake.
P
ND
[kW] Rated power of motor in combination with PMC-2.
