Tubular motors from elero are maintenance-free and have a long life, making them especially suitable for the mentioned applications. Of course, the Type 15 series can be easily combined with the necessary safety technology, such as safety brake and lower rail disconnect, via a motor control unit with radio control.
|
|
The quietly running elero drives are reliable, durable and maintenance-free. They offer you the comfort of operating your roller shutters or awnings automatically by pressing a button instead of via crank drives or belts. The easily installed tubular motors can be fitted into shafts from 40 to 98 mm. They require very little space and are protected against overload by a thermal protection system.

|
The performance of elero's “JA” venetian blind drives can be perfectly adapted to venetian blinds. These reliable drives operate with high precision and are maintenance-free.
The squirrel-cage motors have an integrated thermal protection and conveniently adjustable limit switches with a range of up to max. 85 revolutions. The limit switch adjusting buttons for the upper and lower end position are individually accessible from the outside.

H-compact
Maximum power - minimum size
The increasing significance of energy-saving, environmental legislation, the desire for even smaller dimensions and the demands of domestic and international markets have led to the further development of the H-compact series that has proven itself over the years.
H-compact motors are used in the widest range of industry sectors - such as oil & gas, paper, chemical industry or steel. In these sectors, they are used to drive compressors, blowers, refiners, crushers and air separation systems.
H-compact is available in a version for direct connection to the line supply and in a version for converter operation.
H-compact is also available in an explosion-proof version.
As a result of its innovative technology, H-compact sets new standards for high-voltage motors.

Motors - Rexroth IndraDyn A
IndraDyn A is the new generation of asynchronous motors in the 1 to 100 KW power range, available in four axis heights (100, 130, 160 and 180), with options like high-resolution, single-turn or multi-turn absolute encoders and a brake. The air and liquid-cooled motors provide significant advantages for service and preventive maintenance due to their integrated modular construction. For example, exchanging a cooling fan is possible in a few minutes with the appropriate safety measures, even when the motor is running. This provides substantial advantages when used in decentrally-powered printing machinery, machine tools, plastics machinery and general automation.

Dedicated to racks & pinions drive applications, the KRP+ design is based either on the use of one single unit or on the association of two top quality planetary reducers, mounted in parallel on the machine main frame.
When used as a SingleDRIVE, the KRP+ gives the benefit of an ultra high stiffness feed gearbox, dedicated to high performances rack & pinions drive systems.
When choosing the mechanical preload solution, the KRP+ become a DualDRIVE unit, which achieve the true backlash free feature by torsionally winding one pinion against the other through the rack.
Immediate benefits are to need only one motor, and to dramatically simplify the motor control.
When choosing the Electrical preload solution, the KRP+ is used as a TwinDRIVE unit, where the backlash is cancelled by the opposite torque balance between the two pinions, according with the two motors and drives remote control.

Nexen offers an advanced new technology that revolutionizes linear motion. The Roller Pinion System (RPS) provides zero backlash, very high positional accuracy, unlimited length, very high speeds, 99% efficiency, high rigidity, low noise, low maintenance, corrosion resistance, and long life. This opens up
new design possibilities and provides the capability to achieve much higher levels of performance in machine designs.
The RPS's unique design eliminates many of the limitations of current linear drive systems like:
Ball Screws: Limited by critical speed, maximum speed, cumulative error, vibration, thermal expansion, supplemental cooling, noise, low efficiency, maintenance, and life.
Traditional Rack and Pinion: Limited by low accuracy and speed, backlash, tooth fatigue, noise, high cost of dual and split pinion systems, high maintenance, and short life.
Belt Drives: Limited by low accuracy, backlash, low load capacity, short lengths, belt stretch, and low rigidity.
Linear Motors: Limited by low load capacity, high cost, strong magnetic fields, and liquid cooling.

The most amazing aspect of the DT Series motor is its huge torque potential from its relatively small size. The DT Series motor is capable of producing output torque comparable to competitive designs, but from a package that is both shorter and lighter. The savings in space and weight in no way compromises durability, as the motor uses massive shafts, bearings and drive links to transmit the torque produced by this powerful package. The use of a case drain allows reduced pressure on the shaft seal while maintaining driveline lubrication for maximum motor life. Standard mounting and shaft options offer interchangeability with competitive designs. An internal drain option is also available.
