Energy savings with helical bevel geared motors
Siemens Automation and Drives has developed Flender helical bevel geared motors to serve the food and drink industry, offering high efficiency, lower long-term energy costs and easier maintenance.
New proximity switch for mechanical handling
Siemens Automation and Drives is extending its family of Opto-BERO 3RG7 proximity switches to include a new optical sensor, which has been specifically designed for the mechanical handling market.
Outputs of these two, four, six and eight pole motors are graded in accordance with the IEC.
Pole-changing versions are available for all of the models.
The modular design of the geared motors allows the flexible connection of encoders, braking units and external fans, and can be adapted to individual requirements.

Due to the improved operating characteristics they give to the equipment they control, electronic motor soft starters are increasingly widely applied. Peter Costello of Siemens explains
Legislation reduces bus-based automation costs
The introduction of EN 954-1 and IEC 61508 regulations, which govern machinery safety and electrical controls, open up opportunities for users of networked control systems.
As these motors are embedded in the concepts of Totally Integrated Automation (TIA) and Ecofast, the system for distributed interface technology, they enable integrated system solutions to be implemented at a reasonable price.
In addition, they are compatible with all Siemens converters and are harmonized with one another.
The spur gears are concentrically designed and offer two housing design options: flange or foot mounting.
The housing of the smaller sizes is made from die-cast or permanent-mould aluminium alloy, while the larger units have a grey cast iron housing.
The spur gears are available in two-stage version, and the range of ratios can be increased by means of a flanged-on preliminary stage.
The mitre gears allow users to attach output flanges, baseplates or torque brackets.
For small sizes, the angle stage is a hypoid gear pair that ensures very quiet running and greater gear ratios.
The geared motors have a housing made of aluminium alloy permanent-mould casting and have two stages in the basic version.
The larger, three-stage gears are equipped with a bevel-gear stage and are manufactured from grey cast iron.
The range of ratios for the mitre gears can also be increased by means of a preliminary stage.
The compact construction and low-profile design of the flat gears means they are particularly well suited to space-saving applications.
They can be ordered with either solid or hollow shafts and with various attachment options.
The smaller series have a dimensionally stable, vertically split housing made from die-cast aluminium alloy, whilst the larger gear units have a grey cast iron housing.
The flat gear units are available in both two-stage and three-stage versions.
Helical worm gears also offer the advantage of a variety of attachment options due to their universal design or with a combination of flanges, baseplates and torque brackets.
Solid and hollow shafts in various dimensions and versions are available as input shafts.
The efficiency depends on the gear ratio and thanks to the spur gear input stage, values of up to 90 percent are achieved.
The smaller gear units have a housing of aluminium alloy permanent-mould casting, while the larger ones have a grey cast iron housing.
The worm gear units have two stages in their basic version.
The range of ratios in the larger gear units can be increased by means of a preliminary stage.
