Motor terminal voltage (Fundamental wave only) U
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.
Offset R [mm]
Distance between output bearing and contact point of load.
Pitch circle diameter d
p
Pitch circle diameter of the output bearing.
Protetcion IP

N
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
[Nm], Mechanic
N
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

rms
Supply voltage for operation with rated torque and rated speed.
Ratio i [ ]
The ratio is the reduction of input speed to the output speed.
Note for Harmonic Drive® transmission: The standard version of the wave is generating the drive element, the output element
of the flexspline and the circular Spline is fixed to the housing. Since the direction of rotation of the drive (Wave Generator) to
output reverses (Flexspline), a negative ratio for results Calculations in which the direction of rotation must be considered.
