Direct coupling between servo electric motor and worm gear is among the essential strengths of EP worm gearmotors, which combine DC engine technology with exceptional toughness and wear resistance. Electric motor and gearbox were created as one single, compact unit. Thanks to their reduced current pull, these gearmotors deliver more accurate control of operating temperature and higher performance.

We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or without integrated linear lead screw / ball screw adapted to your flexible modular concept.
Based upon this we can select a wide selection of regular customizations to meet the requirements of various properties that are essential for each application.
If your application requires a gearbox with some special residence such as for example small dimensions or low weight in relation to power, high efficiency, quiet and vibration-free operation, extended life, high level of resistance to vibration, pressure or temperature, integrated linear screw, or a combination of this kind of properties, our product range with an increase of than 1000 different standard gearboxes is most likely a good start to have the ability to deliver a product that stands out on your side.
Compact gearboxes are high-quality gearboxes for standard drives. The electric electric motor is integrated with the gearbox right into a single unit (the first gear is on the electric motor shaft). Separate gearboxes for link with conventional IEC motors can also be supplied on request.
Because of the complexity of the gearboxes’ configuration, they cannot be purchased inside our e-shop. Our professionals will be pleased to help you make your selection. We are happy to send out you documentation or style the right set directly, on request.

Ever-Power worm gearboxes have earned a status to be a business benchmark worldwide. Our success came from our relentless drive for quality with state-of-the-artwork technology, all while offering worm gearboxes are inexpensive prices. High flexibility accorded through a wide choice of mounting options, shaft configurations and motor interfaces, makes the Ever-Power worm gearbox the default choice for the sector. The helical-worm and the double-worm version, with or without the torque limiter, soon add up to the advantage, creating an extremely versatile drive system.
Ever-Power Worm gearboxes provide high torque with low velocity gear ratio. Being simple and compact in style, these gears can achieve higher gear ratio than the helical gears. These worm decrease gears having screw type characteristics are similar to helical gears, but its helix angle is typically comparatively bigger) and its own body is normally quite lengthy in the axial path. The gears in these gearboxes can be correct or left-handed depending upon the purpose.
Mounting choice include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (single or double), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Power gearboxes and geared motors will be the electro-mechanical key elements for low backlash, easily running and highly dynamic drive systems.
Our high-performance gear products are designed to withstand the toughest commercial applications.
The apparatus housings are machined on all sides and permit diverse installation positions and applications, producing them much popular in the industry. Because of this our geared motors are often to be found as part of our customers own devices.
The smooth running of Ever-Power gear units and the outstanding load capacity of WATT teeth are achieved with 3D design backed by FEM (Finite Element Method). This tooth geometry ensures optimum rolling get in touch with under load.
The special tooth root design in mixture with tooth helix angle, tooth depth, the components used and surface finish maximizes load capacity. This high gearing capacity enables smaller wheels to be used for the same torque, and smaller sized gears with outstanding power density also increase reliability. Ever-Power geared motors are as a result incredible space savers.
Gearing produced with such micro-geometric precision allows the gearing play necessary for troublefree rolling contact to be substantially reduced and therefore the gear backlash to end up being minimized.
Double chamber shaft seals produced by Ever-Power are utilized as regular in parallel shaft, shaft mounted and helical worm gears for a higher level of tightness.
Ever-Power’s modular equipment technology meets the requirements of advanced drive systems:
Excellent power density
Diverse mounting options
