Perfect Meshing & Tracking
BRECOflex (Eatontown, NJ) now offers 3 different pulley tooth gap
versions for the “T” and “AT” timing belts. Timing belt pitch tolerances and pulley tooth gap profile – measurements are scientifically
determined, resulting in an efficient belt drive performance. The
proper tooth gap selection depends on the given application and
BRECOflex offers engineering support and recommendations.
The 3 pulley tooth gap versions include:
■ Normal Backlash Tooth Gap.
■ Reduced Backlash “SE” Tooth Gap”.
■ Zero Backlash “0” Tooth Gap.
Metronix (Germany) has announced a new range of servo motor drives
that provide automation builders with a combination of capability and
economy. Called blueServo, the packaged drives combine a universal
real-time Ethernet capability with safe torque off functional safety
and comprehensive encoder interfacing capability - including the
single-cable HIPERFACE DSL scheme. Features include:
■ Continuous output power
ratings from 0.5
to 6 kVA.
■ An embedded
■ A broad encoder
■ Support for the
■ Safe Torque Off
■ An integral line filter
and brake resistors.
■ A Windows-based
software tool for parame-terizing and analyzing the drives.
(Torrance, CA) has
announced the new
RKII Series stepper
motor and driver
packages with built-in controller (stored
data) type and pulse
input type. The new
RKII Series is a solution
for demanding requirements and is available with a built-in controller
(stored data) type driver or pulse input type driver. Features include:
■ Reduced heat output, up to 104°F (40° C) cooler than conventional
■ 100% torque utilization with no compromise.
■ A step angle selector for switching from 1.8° or 0.9° packages.
■ 3 new and improved geared motors.
■ Availability in 42 (1.65”), 60 ( 2. 36”), 85 ( 3. 35”),
and 90 mm ( 3.54”) for geared type.
■ Low vibration.
Siemens Industry (Elk Grove
Village, IL) has announced the
new Sinamics CU250S- 2 control unit for use with its popular
Sinamics G120 variable speed
drives. The unit provides vector
control with encoder feedback.
Typical applications for these
new control units include
single drives with a large
number of I/O or those with
high speed control requirements. Features include:
■ Support for the operation
of single-axis applications
with exact speed and torque
control on induction motors, as well
as positioning tasks with high demand on I/O.
■ Different encoder interfaces provided on the module.
■ Integrated STO (Safe Torque Off), SBC (Safe Brake Control),
and SS1 (Safe Stop 1).
■ An integrated USB port.
■ An integrated slot for an SD card for simple cloning and
firmware updates or upgrades.
