Immediate coupling between servo engine and worm gear is among the important strengths of EP worm gearmotors, which merge DC motor technology with exceptional toughness and wear resistance. Motor and gearbox are designed as one single, compact unit. Because of their reduced current draw, these gearmotors deliver considerably more accurate control of operating temperature and higher effectiveness.

We deliver worm gearboxes, spur gearboxes and planetary gearboxes with as well as without integrated linear lead screw / ball screw adapted to our flexible modular concept.
Based in this we are able to select a wide selection of regular customizations to meet the requirements of varied properties that are essential for each application.
If your application requires a gearbox with some special real estate such as for example small dimensions or low weight in relation to vitality, 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 more than 1000 different standard gearboxes is probably an excellent start to be able to deliver a product that stands out on your side.
Compact gearboxes are high-top quality gearboxes for standard drives. The electric electric motor is integrated with the gearbox right into a single device (the first equipment is directly on the electric motor shaft). Separate gearboxes for connection to conventional IEC motors may also be supplied on request.
Because of the complexity of the gearboxes’ configuration, they cannot be purchased in our e-shop. Our specialists will be happy to help you create your selection. We are happy to send out you documentation or design the right set directly, on request.

Ever-Power worm gearboxes have earned a status to be an industry benchmark worldwide. Our achievement originated from our relentless drive for level of quality with state-of-the-artwork technology, all while offering worm gearboxes happen to be affordable prices. High flexibility accorded through a broad choice of mounting choices, shaft configurations and electric motor interfaces, produces the Ever-Power worm gearbox the default personal preference 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-Vitality Worm gearboxes provide large torque with low rate gear ratio. Being simple and compact in style, these gears can perform higher gear ratio compared to the helical gears. These worm decrease gears having screw type characteristics are similar to helical gears, but its helix angle is typically comparatively larger) and its body is generally quite long in the axial path. The gears in these gearboxes could be ideal or left-handed dependant on the purpose.
Mounting option include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (one or dual), with torque arm or torque limiter.
EXCELLENT Geared Motors. Ever-Vitality gearboxes and geared motors will be the electro-mechanical key components for low backlash, easily running and highly dynamic drive systems.
Our high-performance gear products are designed to withstand the toughest commercial applications.
The gear housings are machined on all sides and invite diverse mounting positions and applications, making them much popular in the industry. Consequently 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 supported simply by FEM (Finite Element Method). This tooth geometry ensures optimum rolling get in touch with under load.
The special tooth root style in mixture with tooth helix angle, tooth depth, the materials used and surface finish maximizes load capacity. This great gearing capacity enables smaller wheels to be used for the exact torque, and smaller sized gears with remarkable power density also increase reliability. Ever-Electrical power geared motors are as a result incredible space savers.
Gearing produced with such micro-geometric accuracy allows the gearing play required for troublefree rolling get in touch with to be substantially reduced and therefore the equipment backlash to become minimized.
Double chamber shaft seals produced by Ever-Power are used as standard in parallel shaft, shaft installed and helical worm gears for a high level of tightness.
Ever-Power’s modular equipment technology meets certain requirements of advanced drive programs:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
