Direct coupling between servo electric motor and worm gear is one of the important strengths of EP worm gearmotors, which combine DC Compact Worm Gearbox engine technology with exceptional sturdiness and wear resistance. Electric motor and gearbox are designed as one single, compact unit. Thanks to their reduced current draw, these gearmotors deliver more accurate control of working 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 variety of standard customizations to meet up the requirements of various properties that are essential for each application.
If your application takes a gearbox with some special house such as for example small dimensions or low weight with regards to power, high efficiency, quiet and vibration-free operation, long life, high level of resistance to vibration, pressure or temperature, integrated linear screw, or a combination of such properties, our product range with an increase of than 1000 different standard gearboxes is probably a good begin to have the ability to deliver a product that stands out in your favor.
Small gearboxes are high-quality gearboxes for standard drives. The electric engine is integrated with the gearbox right into a single device (the first gear is on the motor shaft). Separate gearboxes for connection to conventional IEC motors can also be supplied on request.
Due to the complexity of the gearboxes’ configuration, they cannot be purchased in our e-shop. Our professionals will be happy to help you create your selection. We are happy to send you documentation or design a suitable set directly, on ask for.

Ever-Power worm gearboxes possess earned a status to be an industry benchmark worldwide. Our success originated from our relentless drive for quality with state-of-the-artwork technology, all and will be offering worm gearboxes are affordable 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, add up to the advantage, creating an extremely versatile drive system.
Ever-Power Worm gearboxes provide high torque with low speed gear ratio. Being simple and compact in design, these gears can achieve higher gear ratio than the helical gears. These worm reduction gears having screw type characteristics are similar to helical gears, but its helix position is typically comparatively bigger) and its body is normally quite long in the axial direction. The gears in these gearboxes can be right or left-handed dependant on the purpose.
Mounting option include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (one or double), with torque arm or torque limiter.
EXCELLENT 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 systems are built to withstand the toughest industrial applications.
The gear housings are machined on all sides and permit diverse mounting positions and applications, making them much sought after in the industry. Because of this our geared motors are often to be found within 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 simply by FEM (Finite Element Method). This tooth geometry guarantees optimum rolling contact under load.
The special tooth root style 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 utilized for the same torque, and smaller sized gears with excellent power density can also increase reliability. Ever-Power geared motors are therefore incredible space savers.
Gearing manufactured with such micro-geometric accuracy allows the gearing perform required for troublefree rolling contact to be substantially reduced and then the gear backlash to be minimized.
Double chamber shaft seals developed by Ever-Power are utilized as standard in parallel shaft, shaft mounted and helical worm gears for a high level of tightness.
Ever-Power’s modular gear technology meets certain requirements of advanced drive systems:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
