Helical geared motors are the most regular 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 good shaft is usually used as output shaft. Additional components – e.g. gear tires 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 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 Models have wash-down capability because of their smooth surfaces.
Robust
If required, we can treat Ever-Power Helical Geared Motors with nsd tupH Corrosion Safety, which also withstands aggressive cleaning agents.
Always the right alternative: Our Helical Geared Motors
No two applications are the same. For this reason, 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
Regular Helical Geared Motors have an array of uses and offer confirmed quality. This kind of geared electric motor is obtainable 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 equipment units from extremely wear-resistant, case-hardened steels.
Compact power packs
Our UNICASE Helical Geared Motors have a compact design, with an exceptionally robust grey cast iron housing. They include especially efficient motors in order to operate as effectively as possible, also at the utmost 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 feature is especially important for users in hygienically critical sectors such as the meals or pharmaceutical industries.
According to the size of the gear unit, we produce Ever-Power Helical Gear Models with a die cast aluminium or grey cast iron casing. In this way you obtain optimum functionality with every variant.
The aluminium housing of the Ever-Power series provides organic corrosion protection. Nevertheless we can also provide additional safety if required with the innovative nsd tupH surface area treatment. As opposed to typical paint it cannot flake off – an excellent advantage in harsh conditions. 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 installation. Gear housing machined on all sides for universal program.
Optimized gearing geometry here and in every the other versions results in extraordinary running smoothness. For special environmental conditions the apparatus unit can be fitted with two shaft seals.
