Helical geared motors will be the most standard and cost-effective solution for many drive applications. Helical gear products are coaxial, where in fact the gear unit result shaft is based on the motor shaft. A good shaft is often used as output shaft. Additional parts – e.g. gear wheels or chain wheels – to transfer the pressure to the powered load are for that reason required. Solutions making use of helical geared motors can handle an extremely 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 an array of applications
Motors with a helical equipment unit from Ever-Power possess a high power density and a huge number of choices. The apparatus units are produced in three series and several sizes for a wide range of applications.
Ever-Power Helical Gear Models impress with excellent features:
Powerful
Our helical gear devices give a 
maximum torque of 26,000 Nm (because 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 because of their smooth surfaces.
Robust
If required, we can treat Ever-Power Helical Geared Motors with nsd tupH Corrosion Security, which also withstands aggressive cleaning agents.
Always the right alternative: Our Helical Geared Motors
No two applications are the same. Because of this, Ever-Power supplies three different drive solutions with helical gear units. All variants can be found as flange or foot/flange mounted versions.
The all-rounder
Regular Helical Geared Motors have a wide variety 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 highly wear-resistant, case-hardened steels.
Compact power packs
Our UNICASE Helical Geared Motors have a concise design, with an extremely robust grey cast iron casing. They are equipped with especially efficient motors in order to operate as efficiently as possible, even at the utmost torque of 26,000 Nm.

Easy maintenance: Wash-down capable helical geared motors
With the Ever-Power series we positioned a higher priority on a smooth, easy to clean surface. This characteristic is especially important for users in hygienically vital sectors such as the meals or pharmaceutical industries.
According to the size of the gear unit, we generate Ever-Power Helical Gear Units with a die cast aluminium or grey cast iron housing. In this way you have optimum performance with every variant.
The aluminium housing of the Ever-Power series provides natural corrosion protection. Nevertheless we can also provide additional safety if needed with the innovative nsd tupH surface treatment. In contrast to regular paint it cannot flake off – a great advantage in harsh conditions. Read here how Ever-Power Helical Geared Motors optimise creation at the chocolate producer Zotter in Austria.
Ever-Power design for foot and flange installation. Gear housing machined on all sides for universal application.
Optimized gearing geometry here and in all the other models results in excellent running smoothness. For special environmental conditions the gear unit can be fitted with two shaft seals.
