Helical geared motors are the most conventional and cost-effective solution for many drive applications. Helical gear models are coaxial, where the gear unit result shaft is in line with the motor shaft. A good shaft is always used as result shaft. Additional components – e.g. gear wheels or chain wheels – to transfer the force to the powered load are therefore required. Solutions making use of helical geared motors are capable of an extremely 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).

Helical Geared Motors for a wide range of applications
Motors with a helical gear unit from Ever-Power have a higher power density and a big number of choices. The apparatus units are produced in three series and several sizes for a wide range of applications.
Ever-Power Helical Gear Systems impress with outstanding features:
Powerful
Our helical gear devices provide a maximum torque of 26,000 Nm (as an Industrial gear unit up to 250.000 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 Security, which also withstands intense cleaning agents.
Always the right solution: Our Helical Geared Motors
No two applications are the same. Due to this, Ever-Power items three different drive solutions with helical equipment units. All variants are available as flange or foot/flange mounted versions.
The all-rounder
Standard Helical Geared Motors have a wide range of uses and offer verified quality. This kind of geared motor is offered from Ever-Power in six sizes, in two or three stage variations with torque ranges from 50 to 700 Nm. We produce the apparatus wheels for helical gear units from extremely 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, also at the maximum torque of 26,000 Nm.

Easy maintenance: Wash-down able helical geared motors
With the Ever-Power series we positioned a high priority on a smooth, simple to clean surface. This characteristic is especially important for users in hygienically important sectors such as the food or pharmaceutical industries.
With respect to the size of the gear unit, we create Ever-Power Helical Gear Products with a die cast aluminium or grey cast iron casing. In this way you obtain optimum efficiency with every variant.
The aluminium housing of the Ever-Power series provides natural corrosion protection. Nevertheless we can also provide additional protection if needed with the innovative nsd tupH surface treatment. As opposed to standard paint it cannot flake off – a great advantage in harsh conditions. Read here how Ever-Power Helical Geared Motors optimise creation at the chocolate manufacturer Zotter in Austria.
Ever-Power style for foot and flange installation. Gear housing machined on all sides for universal program.
Optimized gearing geometry here and in all the other versions results in remarkable running smoothness. For special environmental conditions the gear unit can be installed with two shaft seals.
