The rated speed is a reference speed for the calculation of the gear life. When loaded with rated torque and running at
rated speed the Wave Generator Bearing will reach the nominal service life L

Rated torque T [Nm], Servo
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], Mechanical
N
The rated torque is a reference torque for the calculation of the gear life. When loaded with rated torque and running at rated
speed the Wave Generator Bearing will reach the nominal service life L
not used for the dimensioning of the gear.
Rated voltage U [V ]
N 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® Gears: In the standard drive arrangement, the Wave Generator is the drive element while the
Flexspline is the driven element and the Circular Spline is fixed to the housing. Since the direction of rotation of the input
(Wave Generator) is opposite to the output (Flexspline), a negative ratio must be considered.
Repeatability [arcmin]
The repeatability of the gear describes the position differ-
ence measured during repeated movement to the same
desired position from the same direction. The repeatability is
defined as half the value of the maximum difference meas-
ured, preceded by a ± sign.
