Direct coupling between servo motor and worm gear is among the important strengths of EP worm gearmotors, which combine DC electric motor technology with exceptional sturdiness and wear resistance. Electric motor and gearbox were created as you single, compact unit. Thanks to their reduced current draw, 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 our flexible modular concept.
Based on this we are able to select a wide variety of standard customizations to meet up the requirements of various properties that are important for each application.
If your application takes a gearbox with some special home such as for example small dimensions or low weight with regards 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 such properties, our product range with an increase of than 1000 different standard gearboxes is probably a good start to have the ability to deliver something that stands out on your side.
Compact gearboxes are high-quality gearboxes for regular drives. The electric motor is integrated with the gearbox right into a single unit (the first gear is on the engine shaft). Individual gearboxes for link with conventional IEC motors may also be supplied on request.
Due to the complexity of the gearboxes’ configuration, they can not be purchased in our e-shop. Our specialists will be pleased to help you make your selection. We will be happy to send out you documentation or design the right set directly, on request.

Special wishes possible
Ever-Power worm gearboxes have earned a status to be a business benchmark worldwide. Our achievement originated from our relentless drive for quality with state-of-the-art technology, all and will be offering worm 
gearboxes are affordable prices. High versatility accorded through a broad choice of mounting options, shaft configurations and engine 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 a highly versatile drive system.
Ever-Power Worm gearboxes provide high torque with low acceleration gear ratio. Being simple and compact in design, these gears can achieve higher gear ratio compared to the helical gears. These worm reduction gears having screw type qualities are similar to helical gears, but its helix angle is typically comparatively bigger) and its own body is generally quite lengthy in the axial path. The gears in these gearboxes can be correct or left-handed dependant on the purpose.
Mounting option 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.
EXCELLENT Geared Motors. Ever-Power gearboxes and geared motors will be the electro-mechanical key elements for low backlash, efficiently running and highly dynamic drive systems.
Our high-performance gear units are designed to withstand the toughest commercial applications.
The gear housings are machined on all sides and invite diverse installation positions and applications, making them much sought after in the industry. Because of this our geared motors tend to be to be found as part of our customers own machines.
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 get in touch with under load.
The special tooth root design in mixture with tooth helix angle, tooth depth, the materials used and surface finish maximizes load capacity. This high gearing capacity allows smaller wheels to be utilized for the same torque, and smaller sized gears with remarkable power density also increase reliability. Ever-Power geared motors are therefore incredible space savers.
Gearing manufactured with such micro-geometric accuracy allows the gearing play 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 used as regular in parallel shaft, shaft installed 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
