Immediate coupling between servo electric motor and worm gear is among the crucial strengths of EP worm gearmotors, which combine DC electric motor technology with exceptional durability 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 effectiveness.

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 on this we are able to select a wide selection of regular customizations to meet up the requirements of varied 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 in relation to power, high efficiency, quiet and vibration-free operation, long life, high resistance to vibration, pressure or temperature, integrated linear screw, or a combination of this kind of properties, our item range with more than 1000 different standard gearboxes is probably a good start to have the ability to deliver something that stands out in your favor.
Compact gearboxes are high-quality gearboxes for regular drives. The electric motor is built-in with the gearbox right into a single unit (the first gear is on the electric motor shaft). Individual gearboxes for connection to conventional IEC motors may also be supplied on request.
Because of the complexity of the gearboxes’ configuration, they can not be purchased in our e-shop. Our experts will be pleased to help you create your selection. We are happy to send you documentation or style a suitable set directly, on demand.

Ever-Power worm gearboxes have earned a popularity to be an industry benchmark worldwide. Our success originated from our relentless drive for quality with state-of-the-art technology, all while offering worm gearboxes are affordable prices. High flexibility accorded through a broad choice of mounting choices, shaft configurations and motor interfaces, makes the Ever-Power worm gearbox the default choice for the market. The helical-worm and the double-worm edition, 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 quickness gear ratio. Being basic 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 body is normally quite lengthy in the axial path. The gears in these gearboxes could be correct or left-handed depending upon the purpose.
Mounting choice include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (one or dual), 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, efficiently running and highly powerful drive systems.
Our high-performance gear products 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 by FEM (Finite Element Method). This tooth geometry guarantees optimum rolling contact 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 allows smaller wheels to be used for the same torque, and smaller gears with excellent power density also increase reliability. Ever-Power geared motors are consequently incredible space savers.
Gearing manufactured with such micro-geometric accuracy allows the gearing play required for troublefree rolling contact to be substantially decreased and therefore the gear backlash to end up being minimized.
Dual 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 equipment technology meets the requirements of advanced drive systems:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
