Helical geared motors will be the most regular and cost-effective solution for most drive applications. Helical gear models are coaxial, where the gear unit output shaft is in line with the motor shaft. A solid shaft is often used as result shaft. Additional elements – e.g. gear tires or chain wheels – to transfer the pressure to the driven load are for that reason required. Solutions making use of helical geared motors can handle an exceptionally variable speed range.
SIMOGEAR helical geared motors are for sale to 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 gear unit from Ever-Power possess a higher power density and a large number of choices. The gear units are stated in three series and many sizes for an array of applications.
Ever-Power Helical Gear Units impress with exceptional features:
Powerful
Our helical gear products give a maximum torque of 26,000 Nm (since an Industrial gear device up to 250.000 Nm).
Efficient
High efficiency increases the productivity of the application form.
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 intense cleaning agents.
Always the right alternative: Our Helical Geared Motors
No two applications will be 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
Standard Helical Geared Motors have an array of uses and offer tested quality. This kind of geared motor is obtainable 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 equipment 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 effectively as possible, actually at the utmost 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 characteristic is especially very important to users in hygienically important sectors such as the meals or pharmaceutical industries.
According to the size of the apparatus unit, we produce Ever-Power Helical Gear Systems with a die cast aluminium or grey cast iron casing. In this way you have optimum efficiency with every variant.
The aluminium housing of the Ever-Power series provides natural corrosion protection. However we can also provide additional safety if required with the innovative nsd tupH surface treatment. As opposed to conventional 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 mounting. Gear housing machined on all sides for universal software.
Optimized gearing geometry here and in all the other versions results in remarkable running smoothness. For particular environmental conditions the gear unit can be fitted with two shaft seals.
