1.
Motor characteristic values reported in the tables refer
to continuous duty (S1), 50 Hz frequency, ambient temperature
max. 40
°
C, altitude up to 1000 m. above sea level operating
condition.
2.
DC brake is provided on request only on BA series motors
. Brake current consumption values refer to a rated voltage
of 3-phase 400V for
AC brakes and single-phase 230V for
DC brakes.
3.
The table shows the sound pressure noise level, measured
at one metre range from the motor according to the Acurve
(ISO 1680). The shown noise levels refer to motor no-load
operating condition and should be regarded with a tolerance
of
±
3dB.
4.
Max brake torque and Z
0
values refer to AC brake. Go to
pag. 23 for DC max brake torque values.
5.
The expressed Z
0
values refers to AC Brake. Z
0
is the
max number of no-load starts. It is meant for calculation
purposes only, and is used to obtain the max number of
starts with load according to the formula expressed at page
22. The number of starts with load (Zload) is indicative and
it has to be operatively tested for confirmation. The use of
Thermo-protectors is strongly recommended when the
operative number of starts is close to the calculated Zload.
It is necessary to verify the max permissible brake energy
dissipation and the max permissible RPM.
6.
The maximum brake torque for BAK 132 motors series
is 120Nm
