Drive efficiency and economy stepped up a gear

STOBER has developed a new economy version of its PE range of planetary gear units

A new cost-reducing variation of STOBER’s PE range of planetary gear units offers users significantly increased performance, states the company. Featuring STOBER helical gearing, it is said to deliver “exceptionally smooth operation and very low noise, making it unique in its price and product class.

When directly attached to the STOBER IE5-class LeanMotor, the end user benefits from a drive that is both economical and extremely energy efficient”.

Backlash stability and long service life

With customers in the automation and packaging industries looking for a diverse range of dynamic precision drive options for demanding operations, the new PE economy range incorporates backlash stability and long service life.

Another benefit to machine builders and end users is that these new PE gear units are equipped with helical gearing, adds STOBER, “so, when compared to the straight-cut gear units common in the sector, this results in very smooth power transmission and low operational noise”.

As Michael Oberländer, STOBER’s head of gear unit development, further comments: “In this new economy variation, we increased the acceleration torque by forty-five per cent and the nominal torque by fifty per cent, which gives a very significant improvement in performance. The two-stage variant is also shorter and, as a result of these developments, the new economy gear units are lighter and more compact overall.”

Compatibility advantages

STOBER has also matched the interfaces of this economy version to their high-performance 3rd generation planetary gear units, meaning that both smaller STOBER motors and third-party motors can be integrated in direct attachment, and with an adapter in the economy version.

“The Encoderless LeanMotor from STOBER is an extremely innovative motor, that provides efficiency up to ninety-six percent, along with the IE5 energy efficiency classification,” adds the company. “In direct attachment with a PE gear unit, this synchronous servo motor forms a highly compact and economical drive unit. Pairing the LeanMotor with an SC6 or SI6 slim drive controller creates a powerful drive system, the components of which can then be combined with a wide range of STOBER products.

“As a result, the designer benefits from single-source specification from a supply partner, with comprehensive drive and motion control expertise that gives designers, engineers and end users total confidence in their choice of system provider, the implementation of drive functionality and problem-solving capability.”
