Direct coupling between servo motor and worm gear is one of the key strengths of EP worm gearmotors, which combine DC engine technology with exceptional strength and wear resistance. Electric motor and gearbox are designed as one single, compact unit. Thanks to their reduced current attract, these gearmotors deliver more accurate control of operating temperature and higher efficiency.

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 selection of standard customizations to meet the requirements of varied 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 combination of such properties, our product range with more than 1000 different standard gearboxes is most likely a good start to have the ability to deliver something that stands out on your side.
Small gearboxes are high-quality gearboxes for standard drives. The electric engine is built-in with the gearbox right into a single device (the first gear is directly on the engine shaft). Individual gearboxes for connection to conventional IEC motors can also be supplied on request.
Because of the complexity of the gearboxes’ configuration, they can not be purchased inside our e-shop. Our professionals will be happy to help you make your selection. We will be happy to send you documentation or design a suitable set directly, on ask for.

Ever-Power worm gearboxes have earned a status to be an industry benchmark worldwide. Our success came from our relentless drive for quality with state-of-the-artwork technology, all while offering worm gearboxes are inexpensive prices. High versatility accorded through a wide choice of mounting options, shaft configurations and engine interfaces, makes the Ever-Power worm gearbox the default choice for the market. 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 rate gear ratio. Being simple and compact in design, these gears can achieve higher gear ratio compared to the helical gears. These worm decrease gears having screw type qualities act like helical gears, but its helix position is typically comparatively bigger) and its body is normally quite lengthy in the axial direction. The gears in these gearboxes can be right or left-handed dependant on the purpose.
Mounting option include universal housing, aspect 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 are the electro-mechanical key elements for low backlash, efficiently running and highly powerful drive systems.
Our high-performance gear systems are built to withstand the toughest commercial applications.
The gear housings are machined on all sides and invite diverse mounting positions and applications, producing them much popular in the industry. As a result our geared motors are often 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 simply by FEM (Finite Element Method). This tooth geometry ensures optimum rolling get in touch with under load.
The special tooth root design in combination with tooth helix angle, tooth depth, the materials used and surface finish maximizes load capacity. This high gearing capacity allows smaller wheels to be used for the same torque, and smaller sized gears with excellent power density can also increase reliability. Ever-Power geared motors are as a result incredible space savers.
Gearing produced with such micro-geometric accuracy allows the gearing play necessary for troublefree rolling get in touch with to be substantially reduced and then the gear backlash to end up being minimized.
Dual chamber shaft seals produced by Ever-Power are utilized 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
