Direct coupling between servo electric motor and worm gear is among the essential strengths of EP worm gearmotors, which combine DC electric motor technology with exceptional sturdiness and wear resistance. Engine and gearbox are designed as one single, compact unit. Because of 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 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 house such as for example small dimensions or low weight in relation to power, high efficiency, quiet and vibration-free operation, extended life, high resistance to vibration, pressure or temperature, integrated linear screw, or a mixture of this kind of properties, our item range with more than 1000 different standard gearboxes is most likely a good start to have the ability to deliver a product that stands out in your favor.
Compact gearboxes are high-quality gearboxes for standard drives. The electric electric motor is integrated with the gearbox into a single unit (the first gear is on the electric motor shaft). Separate gearboxes for connection to conventional IEC motors may also be supplied on request.
Due to the complexity of the gearboxes’ configuration, they cannot be purchased inside our e-shop. Our professionals will be happy to help you create your selection. We are happy to send out you documentation or design the right set directly, on demand.

Ever-Power worm gearboxes possess earned a popularity to be an industry benchmark worldwide. Our achievement originated from our relentless drive for quality with state-of-the-artwork technology, all while offering worm gearboxes are inexpensive prices. High flexibility accorded through a wide choice of mounting options, shaft configurations and electric 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, soon add up to the advantage, creating a highly versatile drive system.
Ever-Power Worm gearboxes provide high torque with low rate gear ratio. Being simple and compact in design, these gears can perform higher gear ratio compared to the helical gears. These worm reduction gears having screw type qualities act like helical gears, but its helix angle is typically comparatively bigger) and its body is generally quite long in the axial direction. The gears in these gearboxes can be correct or left-handed dependant on the purpose.
Mounting option include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (single or double), with torque arm or torque limiter.
EXCELLENT Geared Motors. Ever-Power gearboxes and geared motors will be the electro-mechanical key components for low backlash, smoothly running and highly dynamic drive systems.
Our high-performance gear devices are designed to withstand the toughest commercial applications.
The gear housings are machined on all sides and invite diverse mounting positions and applications, producing them much sought after in the industry. Consequently our geared motors tend to be 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 supported by FEM (Finite Element Method). This tooth geometry guarantees 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 enables smaller tires to be used for the same torque, and smaller sized gears with exceptional 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 necessary for troublefree rolling contact to be substantially reduced and therefore the gear backlash to become minimized.
Double chamber shaft seals developed by Ever-Power are used as regular in parallel shaft, shaft mounted 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
Diverse mounting options
