Immediate coupling between servo electric motor and worm gear is one of the key strengths of EP worm gearmotors, which combine DC motor technology with exceptional sturdiness and wear resistance. Motor and gearbox are designed as one single, compact unit. Thanks to their reduced current pull, 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 upon this we can select a wide selection of standard customizations to meet up the requirements of varied properties that are important for each application.
If your application takes a gearbox with some special house such as small dimensions or low weight in relation 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 item range with more than 1000 different standard gearboxes is most likely a good start to be able to deliver a product that stands out in your favor.
Small gearboxes are high-quality gearboxes for standard 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 can also be supplied on request.
Due to the complexity of the gearboxes’ configuration, they cannot be purchased in our e-shop. Our experts will be happy to help you make your selection. We are happy to send you documentation or design a suitable set directly, on request.

Ever-Power worm gearboxes possess earned a reputation to be a business benchmark worldwide. Our achievement came from our relentless drive for quality with state-of-the-art technology, all and will be offering worm gearboxes are affordable prices. High flexibility accorded through a wide choice of mounting choices, shaft configurations and motor interfaces, makes the Ever-Power worm gearbox the default choice for the industry. 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 swiftness gear ratio. Being basic and compact in design, these gears can perform higher gear ratio than the helical gears. These worm decrease gears having screw type qualities act like helical gears, but its helix angle is typically comparatively larger) and its body is normally quite long in the axial path. The gears in these gearboxes could be correct or left-handed dependant on the purpose.
Mounting choice include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (solitary 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, smoothly running and highly powerful drive systems.
Our high-performance gear systems are designed to withstand the toughest commercial applications.
The gear housings are machined on all sides and permit diverse mounting positions and applications, producing them much popular in the industry. Consequently our geared motors tend to be to be found within 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 supported by FEM (Finite Element Method). This tooth geometry ensures optimum rolling contact under load.
The special tooth root design in combination with tooth helix angle, tooth depth, the components used and surface finish maximizes load capacity. This high gearing capacity allows smaller wheels to be utilized for the same torque, and smaller gears with exceptional power density can also increase reliability. Ever-Power geared motors are as a result incredible space savers.
Gearing manufactured with such micro-geometric accuracy allows the gearing perform required for troublefree rolling get in touch with to be substantially decreased and then the gear backlash to become minimized.
Double chamber shaft seals developed by Ever-Power are utilized as standard in parallel shaft, shaft mounted and helical worm gears for a higher level of tightness.
Ever-Power’s modular gear technology meets certain requirements of advanced drive systems:
Excellent power density
Diverse mounting options
