Motor terminal voltage (Fundamental wave only) U
M
[V
rms
]
Required fundamental wave voltage to achieve the specified performance. Additional power losses can lead to restriction of
the maximum achievable speed.
Number of pole pairs p
Number of magnetic pole pairs on the rotor of the motor.
Oset R [mm]
Distance between output bearing and contact point of the load.
Pitch circle diameter d
p
[mm]
Pitch circle diameter of the output bearing rolling elements.
Protection IP
The degree of protection according to EN 60034-5 provides suitability for various environmental conditions.
Rated current I
N
[A]
RMS value of the sinusoidal current when driven at rated torque and rated speed.
Rated motor speed n
N
[rpm]
The motor speed which can be continuously maintained when driven at rated torque T
N
, when mounted on a suitably dimen-
sioned heat sink.
Rated power P
N
[W]
Output power at rated speed and rated torque.
Rated speed n
N
[rpm], Mechanical
The rated speed is a reference speed for the calculation of the gear life. When loaded with the rated torque and running at
rated speed the gear will reach the expected operating life L
50
. The speed n
N
is not used for dimensioning the gear.
Rated torque T
N
[Nm], Servo
The output torque which can be continuously transmitted when driven at rated input speed, when mounted on a suitably
dimensioned heat sink.
Rated torque T
N
[Nm], Mechanical
The rated torque is a reference torque for the calculation of the gear life. When loaded with the rated torque and running at
rated speed the gear will reach the average life L
50
. The rated torque T
N
is not used for the dimensioning of the gear.
