4.1.10 Gear efficiency
The specified gear efficiencies h
G
and h
G´
are extreme values which are to be
applied for dimensioning the motor, frequency inverter and braking resistor,
etc. The rated efficiency h
n
provides information on the value h
G
that can be
achieved under optimum operating conditions.
The efficiencies han and han' describe the state of gear starting (overcoming
static friction or build-up of lubricating film in the gear teeth; at h
an
- values <
0.5 - the gear, when stopped, must be viewed as self-inhibiting).
▪
h

The following values for the machine apply to the ISIS1 versions depending on
the motor construction size:
▪
E 5.5 J
rot
= 0.028 kgm2
▪
E 7.5 J
rot
= 0.036 kgm2
▪
E 11.0 J
rot
= 0.040 kgm2
The mass moment of inertia for versions of the machine not listed in the table
is to be determined according to the details of the individual components.
