- New Compact Torque Motor from Siemens
The recent launch of Siemens 1FW3 torque motors
opens up new exciting possibilities for machine designers
in the field of mechatronics.
1FW3
torque motors are high torque low speed permanent magnet synchronous
AC motors designed to replace standard electrical drives comprising
an electric motor, gearbox and belt connection. They are also
suitable for replacing hydraulic motors.
Applications
requiring a torque range of between 200Nm and 7000Nm
(power ratings 8 to 146kW) at variable speeds up
to 400 or 500 rpm are where the 1FW3 shines and our Masterdrive
MC AC servo drive is the perfect partner (you need version
2).
1FW3
complete torque motors eliminate time-consuming installation
and mounting procedures. This is because this drive solution
reduces the number of components which have to be mounted
in the assembly phase. The hollow shaft allows you to implement
more flexible mechanical design and maintenance concepts.
The 1FW3 plays a significant role in increasing the reliability
and cost-effective use of your production machines.
Application
examples:
- Drive for extruder screws in plastic injection molding
machines
- Roller drive in web or foil production machines,
- CI drives for flexographic printing machines
- Innovative direct drive solutions in paper, packaging,
steel and textile machines.
- Synchronised Transfer Presses
Advantages
against a typical AC Drive, motor and gearbox:
- Direct drive with no backlash.
- Silent running with no fan and no gearbox or belt noise.
- Integrated direct measuring system (multi pole resolver,
1Vpp encoder or EnDat absolute) for accurate measurement.
- Dramatically reduced size due to water cooling.
- High torque from zero speed to rated speed (250/200 rpm)
and typically 50% of rated torque at 2 x rated speed.
- Higher dynamic performance due to very low inertia
- Extremely easy to direct mount - hollow shaft eliminates
cost of mounting and supporting frame necessary for foot
mounted motor.
- Dramatically lower current rating enables cost saving
for servo drive and reduces cable sizes.
- Water cooling eliminates need for ducted cooling systems
for machines in damp areas.
The innovative 1FW3
torque motor from Siemens clearly is the future where high
torque is necessary at speeds up to 500 rpm.
