Helical geared motors are the most standard and cost-effective solution for most drive applications. Helical gear products are coaxial, where the gear unit result shaft is in line with the motor shaft. A solid shaft is always used as result shaft. Additional elements – e.g. gear wheels or chain wheels – to transfer the power to the driven load are as a result required. Solutions making use of 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 device torques up to 5,900 ft-lb (8,000 Nm).

Helical Geared Motors for a wide selection of applications
Motors with a helical gear unit from Ever-Power possess a high power density and a big number of choices. The apparatus units are stated in three series and many sizes for a wide range of applications.
Ever-Power Helical Gear Models impress with outstanding features:
Powerful
Our helical gear models provide a maximum torque of 26,000 Nm (since an Industrial gear unit up to 250.000 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 can treat Ever-Power Helical Geared Motors with nsd tupH Corrosion Protection, which also withstands aggressive cleaning agents.
Always the right option: Our Helical Geared Motors
No two applications are the same. For this reason, Ever-Power materials three different drive solutions with helical gear units. All variants are available 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 electric motor is obtainable 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 gear 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 casing. They are equipped with especially efficient motors in order 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 higher priority on a smooth, easy to clean surface. This feature is especially very important to users in hygienically vital sectors such as the food or pharmaceutical industries.
Based on 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 housing of the Ever-Power series provides natural corrosion protection. Nevertheless we can also provide additional protection if necessary with the innovative nsd tupH surface treatment. As opposed to regular paint it cannot flake off – an excellent advantage in harsh conditions. Read here how Ever-Power Helical Geared Motors optimise production at the chocolate manufacturer Zotter in Austria.
Ever-Power style for foot and flange mounting. Gear housing machined on all sides for universal program.
Optimized gearing geometry here and in every the other versions results in excellent running smoothness. For particular environmental conditions the gear unit can be fitted with two shaft seals.
