Helical geared motors will be the most typical and cost-effective solution for most drive applications. Helical gear systems are coaxial, where the gear unit output shaft is based on the motor shaft. A good shaft is at all times used as result shaft. Additional elements – e.g. gear wheels or chain tires – to transfer the drive to the powered load are therefore required. Solutions utilizing helical geared motors can handle an exceptionally variable speed range.
SIMOGEAR helical geared motors are available for the power 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 form.
Hygienic
Ever-Power Helical Gear Systems have wash-down capability because of their smooth surfaces.
Robust
If required, we are able to treat Ever-Power Helical Geared Motors with nsd tupH Corrosion Security, which also withstands intense cleaning agents.
Always the right solution: Our Helical Geared Motors
No two applications are the same. Because of 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
Regular Helical Geared Motors have an array of uses and offer proven quality. This type of geared engine 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 gear wheels for helical equipment 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 housing. They are equipped with especially efficient motors to be able to operate as efficiently as possible, actually at the maximum torque of 26,000 Nm.

Easy maintenance: Wash-down able helical geared motors
With the Ever-Power series we placed a high 
priority on a smooth, easy to clean surface. This characteristic is especially important for users in hygienically essential sectors such as the food or pharmaceutical industries.
According to the size of the apparatus unit, we generate Ever-Power Helical Gear Units with a die cast aluminium or grey cast iron housing. In this way you obtain optimum efficiency with every variant.
The aluminium casing of the Ever-Power series provides natural corrosion protection. However we can provide additional safety if required with the innovative nsd tupH surface treatment. As opposed to typical paint it cannot flake off – an excellent advantage in harsh environments. Read here how Ever-Power Helical Geared Motors optimise production at the chocolate manufacturer Zotter in Austria.
Ever-Power design for foot and flange mounting. Gear housing machined on all sides for universal software.
Optimized gearing geometry here and in every the other models results in exceptional running smoothness. For unique environmental conditions the gear unit can be fitted with two shaft seals.
