Helical geared motors will be the most standard and cost-effective solution for most drive applications. Helical equipment systems are coaxial, where in fact the gear unit output shaft is based on the motor shaft. A good shaft is always used as result shaft. Additional components – e.g. gear tires or chain tires – to transfer the drive to the driven load are therefore required. Solutions making use of helical geared motors can handle an extremely 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).

Helical Geared Motors for an array of applications
Motors with a helical equipment unit from Ever-Power possess a higher power density and a sizable number of choices. The apparatus units are stated in three series and many sizes for a wide variety of applications.
Ever-Power Helical Gear Products impress with excellent features:
Powerful
Our helical gear products give a maximum torque of 26,000 Nm (because an Industrial gear unit up to 250.000 Nm).
Efficient
High efficiency escalates the productivity of the application.
Hygienic
Ever-Power Helical Gear Units 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 Protection, which also withstands intense cleaning agents.
Always the right option: Our Helical Geared Motors
No two applications will be the same. Because of this, Ever-Power items 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 motor is obtainable from Ever-Power in six sizes, in several 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 concise design, with an exceptionally robust grey cast iron casing. They include especially efficient motors in order to operate as efficiently as possible, even 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, easy to clean surface. This characteristic is especially very important to users in hygienically essential sectors such as the food or pharmaceutical industries.
Depending on 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 performance with every variant.
The aluminium housing of the Ever-Power series provides natural corrosion protection. However we can provide additional security if necessary with the innovative nsd tupH surface treatment. As opposed to regular paint it cannot flake off – an excellent advantage in harsh environments. 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 application.
Optimized gearing geometry here and in every the other models results in exceptional running smoothness. For particular environmental conditions the gear unit can be fitted with two shaft seals.
