Helical geared motors will be the most conventional and cost-effective solution for many drive applications. Helical gear models are coaxial, where in fact the gear unit output shaft is in line with the motor shaft. A good shaft is always used as result shaft. Additional parts – e.g. gear tires or chain wheels – to transfer the power to the powered load are for that reason required. Solutions making use of helical geared motors are capable of an exceptionally variable speed range.
SIMOGEAR helical geared motors are available for the energy range up to 20 HP (15 kW) and rated gear device torques up to 5,900 ft-lb (8,000 Nm).

Efficient
High efficiency escalates 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 Protection, which also withstands intense cleaning agents.
Always the right answer: Our Helical Geared Motors
No two applications are the same. Because of this, Ever-Power materials three different drive solutions with helical gear units. All variants can be found as flange or foot/flange mounted versions.
The all-rounder
Regular Helical Geared Motors have a wide range of uses and offer confirmed quality. This type of geared engine is offered from Ever-Power in six sizes, in several stage versions with torque ranges from 50 to 700 Nm. We produce 
the gear wheels for helical gear units from highly wear-resistant, case-hardened steels.
Compact power packs
Our UNICASE Helical Geared Motors have a concise design, with an exceptionally robust grey cast iron casing. They are equipped with especially efficient motors in order to operate as efficiently as possible, even at the maximum torque of 26,000 Nm.

Easy maintenance: Wash-down capable helical geared motors
With the Ever-Power series we placed a higher priority on a smooth, simple to clean surface. This characteristic is especially important for users in hygienically critical sectors like the food or pharmaceutical industries.
With respect to 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 obtain optimum performance with every variant.
The aluminium casing of the Ever-Power series provides natural corrosion protection. However we can also provide additional protection if necessary with the innovative nsd tupH surface area treatment. In contrast to regular paint it cannot flake off – an excellent 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 mounting. Gear housing machined on all sides for universal application.
Optimized gearing geometry here and in every the other models results in outstanding running smoothness. For particular environmental conditions the gear unit can be installed with two shaft seals.
