New generation of hollow shaft motors

Published

on

 

New additions to the family of innovative hollow shaft drives and screw drives from STOBER

 

The focus here is on the EZHD synchronous servo motor with hollow shaft that with its new bearing technology in all versions can offer a far higher shaft load than to date as well as an integrated brake. With the newly added size 4, STOBER is rounding out the bottom end of the program. The outstanding feature of these motors is the exceptionally large inside diameter of the hollow shaft flange that is ideally suited for the lead-through of energy and media of all kinds.

 

Despite the size of the hollow shaft, these motors offer an exceptional power density with their orthocyclically linear-wound motor coils. The use of the flange hollow shaft for direct connection to the load results in a completely backlash-free, differentiated and smooth drive behavior.

 

In addition to the EZHD synchronous servo motor with hollow shaft described, the STOBER product relaunch also includes the EZHP synchronous servo geared motor with hollow shaft and the EZM synchronous servo motor for screw drives.

Bauer BK Series Geared Motors for Pizza Packaging Line Conveyors

Published

on

One of the world’s largest food and beverage companies needed an efficient, reliable drive for a pizza packaging line in one of its plants in Italy. The drives power shrink wrapping machine infeed conveyors. The facility had been using traditional stainless steel motors rated at 70-80 Hz. However, to boost production, the speed was increased to 80-90 Hz which created excessive heat causing the drives to fail.

After a careful analysis of the conveyor application demands, Bauer engineers recommended a BK Series right angle bevel geared motor for improved efficiency compared to worm gear solutions. The Model BK06 supplied features a PMSM (permanent magnet synchronous motor) that reduces heat losses from the rotor by 100% and total losses by approximately 25%, while increasing total efficiency by 10% or more. This improved performance translates into lower total cost of ownership, a reduction in CO2 emissions, and ongoing savings that buffer against future increases in energy costs.

Because PMSM motors provide efficiency at a wide range of speeds, it allowed the conveyor line speed to be adjusted up to 80 RPM when needed to meet production schedule targets.

Compact Bauer BK Series models are completely enclosed and sealed against dust and moisture. A hardened wear sleeve and spray ring ensure leak-free performance.

NORD smooth motors ideal for the food and beverage industry

Published

on

From its own production, NORD DRIVESYSTEMS offers ventilated and unventilated motors with smooth surfaces for areas with high hygiene standards. Their washdown-optimised cast aluminium housings make them easy to clean.

The smooth surface motors from NORD are available in sizes BG 80, 90 and 100. They are based on the NORD modular construction system and therefore offer maximum flexibility for versatile application areas. The motors are provided with protection class IP66 and they are compatible with every gear unit type. In addition, the use of energy-saving three-phase motors ensures high efficiency with low operating costs.

Optionally, the smooth surface motors are available with the nsd tupH surface treatment, which is a special process making the aluminium surface corrosion-resistant and particularly hard, similar to the qualities of stainless steel. In contrast to protective painting or coating, nothing can detach or flake off.

Shaft height record for high-torque motors

Published

on

Baumüller is expanding its portfolio of high-torque motors with a shaft height of 560 mm.

Baumüller is breaking its own shaft height record with the current expansion of its motor portfolio. With a shaft height of 560 mm, the new DST2-560 high-torque motors are now the largest motors that the manufacturer and pioneer of direct drive technology offers in series production.

High torque for industrial use

With a maximum torque of up to 80,000 Nm, the motors are suitable for use in various industries and systems, such as servo presses, extruders and shredders. The water-cooled high-torque motors offer very high torques even at low speeds and also impress with outstanding true running characteristics, a robust design and a smooth housing surface that is not prone to accumulating dirt.

Powerful and clean alternative for ships

Specifically designed for use in ships, the DST2-560 is optionally also available with so-called wing mounts. These feet diametrically arranged on the outer diameter of the motor make it easier to integrate it into the ship design. In addition, the high-torque motors have already been prepared for approval according to Lloyd’s Register and the DNV GL. With degrees of efficiency of 96% over a broad speed range, the DST2-560 motors are very energy-efficient.
