Helical geared motors will be the most standard and cost-effective solution for most drive applications. Helical gear systems are coaxial, where in fact the gear unit output shaft is good motor shaft. A good shaft is often used as result shaft. Additional components – e.g. gear wheels or chain wheels – to transfer the drive to the driven load are therefore required. Solutions utilizing helical geared motors can handle an exceptionally variable speed range.
SIMOGEAR helical geared motors are available for the energy range up to 20 HP (15 kW) and rated gear unit torques up to 5,900 ft-lb (8,000 Nm).

Efficient
High efficiency increases the productivity of the application.
Hygienic
Ever-Power Helical Gear Systems have wash-down capability thanks to their smooth surfaces.
Robust
If required, we are able to treat Ever-Power Helical Geared Motors with nsd tupH Corrosion Safety, which also withstands intense cleaning agents.
Always the right option: Our Helical Geared Motors
No two applications are the same. Due to this, Ever-Power supplies three different drive solutions with helical equipment units. All variants can be found as flange or foot/flange mounted versions.
The all-rounder
Standard Helical Geared Motors have an array of uses and offer verified quality. This type of geared electric motor is available from Ever-Power in six sizes, in two or three stage versions with torque ranges from 50 to 700 Nm. We produce the apparatus wheels for helical equipment units from extremely wear-resistant, case-hardened steels.
Compact power packs
Our UNICASE Helical Geared Motors have a compact design, with an extremely robust grey cast iron housing. They are equipped with especially efficient motors to be able to operate as effectively as possible, also at the utmost torque of 26,000 Nm.

Easy maintenance: Wash-down capable helical geared motors
With the Ever-Power series we positioned a high priority on a smooth, easy to clean surface. This characteristic is especially very important to users in hygienically vital sectors like the meals or pharmaceutical industries.
Depending on the size of the apparatus unit, we create Ever-Power Helical Gear Units with a die cast aluminium or grey cast iron casing. In this way you have optimum performance with every variant.
The aluminium casing of the Ever-Power series provides organic corrosion protection. However we can provide additional safety if necessary with the innovative nsd tupH surface treatment. In contrast to typical paint it cannot flake off – a great advantage in harsh environments. Read right here how Ever-Power Helical Geared Motors optimise production at the chocolate producer Zotter in Austria.
Ever-Power design for foot and flange installation. Gear housing machined on all sides for universal program.
Optimized gearing geometry here and in every the other versions results in exceptional running smoothness. For particular environmental conditions the gear unit can be installed with two shaft seals.
