Immediate coupling between servo electric motor and worm gear is one of the important strengths of EP worm gearmotors, which combine DC engine technology with exceptional durability and wear resistance. Electric motor and gearbox are designed as you single, compact unit. Thanks to their reduced current draw, these gearmotors deliver more accurate control of working 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 on this we can select a wide variety of regular customizations to meet up the requirements of varied properties that are essential for each application.
If your application requires a gearbox with some special property or home such as small dimensions or low weight in relation to power, high efficiency, quiet and vibration-free operation, long life, high resistance to vibration, pressure or temperature, integrated linear screw, or a mixture of such properties, our item range with more than 1000 different standard gearboxes is probably a good start to be able to deliver a product that stands out in your favor.
Compact gearboxes are high-quality gearboxes for regular drives. The electric motor is integrated with the gearbox right into a single device (the first gear is on the electric motor shaft). Separate gearboxes for link with conventional IEC motors can also be supplied on request.
Because of the complexity of the gearboxes’ configuration, they can not be purchased in our e-shop. Our specialists will be happy to help you make your selection. We will be happy to send you documentation or style a suitable set directly, on demand.

Ever-Power worm gearboxes possess earned a reputation 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 affordable prices. High versatility accorded through a broad choice of mounting options, shaft configurations and engine interfaces, makes the Ever-Power worm gearbox the default choice for the industry. The helical-worm and the double-worm edition, 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 than the helical gears. These worm reduction gears having screw type qualities act like helical gears, but its helix angle is typically comparatively larger) and its body is normally quite lengthy in the axial direction. The gears in these gearboxes could be right or left-handed dependant on the purpose.
Mounting choice include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (one or double), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Power gearboxes and geared motors will be the electro-mechanical key components for low backlash, smoothly running and highly powerful drive systems.
Our high-performance gear models are built to withstand the toughest commercial applications.
The apparatus housings are machined on all sides and invite diverse installation positions and applications, making them much sought after in the industry. As a result our geared motors are often 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 backed by FEM (Finite Element Method). This tooth geometry ensures optimum rolling get in touch with under load.
The special tooth root design in mixture with tooth helix angle, tooth depth, the materials used and surface finish maximizes load capacity. This high gearing capacity allows smaller tires to be used for the same torque, and smaller gears with extraordinary power density also increase reliability. Ever-Power geared motors are therefore incredible space savers.
Gearing produced with such micro-geometric precision allows the gearing perform necessary for troublefree rolling get in touch with to be substantially decreased and then the gear backlash to be minimized.
Double chamber shaft seals developed by Ever-Power are utilized as regular in parallel shaft, shaft installed 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
