Direct coupling between servo electric motor and worm gear is among the important strengths of EP worm gearmotors, which incorporate DC motor technology with exceptional sturdiness and wear resistance. Engine and gearbox were created as one single, compact unit. Thanks to their reduced current draw, these gearmotors deliver even more accurate control of operating temperature and higher effectiveness.

We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or without integrated linear business lead screw / ball screw adapted to your flexible modular concept.
Based at this we can select a wide variety of regular customizations to meet the requirements of varied properties that are essential for each application.
If your application takes a gearbox with some special home such as small dimensions or low weight in relation to electricity, high efficiency, quiet and vibration-free operation, long life, high resistance to vibration, force or temperature, integrated linear screw, or a combination of such 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 something that stands out in your favor.
Small gearboxes are high-quality gearboxes for regular drives. The electric motor is built-in with the gearbox into a single unit (the first gear is on the 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 inside our e-shop. Our specialists will be happy to help you create your selection. We are pleased to send you documentation or design the right set directly, on demand.

Ever-Power worm gearboxes possess earned a reputation to be a business benchmark worldwide. Our success came from our relentless travel 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 options, shaft configurations and motor interfaces, will make the Ever-Electrical power worm gearbox the default decision for the industry. The helical-worm and the double-worm edition, with or without the torque limiter, add up to the advantage, creating an extremely versatile drive system.
Ever-Ability Worm gearboxes provide substantial torque with low velocity gear ratio. Being basic and compact in design, these gears can achieve higher gear ratio compared to the helical gears. These worm decrease gears having screw type qualities are similar to helical gears, but its helix angle is typically comparatively larger) and its own body is generally quite long in the axial path. The gears in these gearboxes could be suitable or left-handed depending upon the purpose.
Mounting option include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (solitary or double), with torque arm or torque limiter.
EXCELLENT Geared Motors. Ever-Electricity gearboxes and geared motors will be the electro-mechanical key components for low backlash, easily running and highly powerful drive systems.
Our high-performance gear systems are built to withstand the toughest industrial applications.
The gear housings are machined on all sides and invite diverse installation positions and applications, making them much popular in the industry. As a result our geared motors tend to be 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 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 excessive gearing capacity allows smaller wheels to be used for the exact torque, and smaller gears with excellent power density also increase reliability. Ever-Electricity geared motors are as a result incredible space savers.
Gearing produced with such micro-geometric accuracy allows the gearing play necessary for troublefree rolling contact to be substantially decreased and therefore the equipment backlash to become minimized.
Dual chamber shaft seals produced by Ever-Power are utilized as standard through 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
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
