New Products
Emerson (Eden Prairie, MN) has expanded its
Control Techniques variable speed drive range
with two new models designed specifi cally for ap-
plications which demand high speeds. The Unid-
rive HS30 and HS70 variable speed drives, capa-
ble of output frequencies of 3,000 Hz, are suited
to applications frequently required for automotive
and aeronautical engine and transmission line test
equipment, machine tool manufacture and centri-
fuges for the food & beverage and oil industries.
The new drives are controlled products under new
laws in the EU and USA covering the export of
'dual use' goods, software and technology. This
refers to items normally used for civilian purposes
but which may have military applications, or may
contribute to the proliferation of weapons of mass
destruction. OEMS and
machine builders which
incorporate high speed
drives in their designs are
responsible for checking
and evaluating whether or
not their machines comply
with, or contravene, the
relevant legislation. In or-
der to assist its custom-
ers, Control Techniques
has introduced the Uni-
drive HS range of high
frequency variable speed
drives.Unidrive HS70 of-
fers class-leading induc-
tion, permanent magnet
and servo motor perfor-
mance, with on-board
real time Ethernet. It pro-
vides maximum control
of high speed motors
and incorporates an on-
board Advanced Mo-
tion Controller and PLC.
Different variations of
Unidrive HS70 are avail-
able, including models
with on-board Ethernet,
RS485 and Dual Safe
Torque Off (Dual STO).
Unidrive HS30 is de-
signed for applications
that require cost effective
integration into safety
systems and incorpo-
rates Dual STO and
advanced Rotor Flux
Control of open loop in-
duction motors. The ex-
isting Unidrive M models,
which are restricted to a
frequency of 550 Hz, are
uncontrolled products in
the eyes of the new laws
in the EU and USA re-
stricting the sale of vari-
able speed drives with
an output frequency of
higher than 600 Hz. This
means no export restric-
tions reply.
In order to comply with
the new legislation,
businesses which ex-
port goods or machines
that incorporate goods
classed as dual use un-
der the terms of the EU
regulation to locations
outside the EU must ap-
ply for the relevant ex-
port licenses from their
respective governments.
The changes also have
an effect on the docu-
mentation required in any
transaction, as well as
the measures which are
taken to securely store
the controlled goods.
