Worm gear motors/variants

SEVA-tec GmbH specializes in addressing complex challenges in the field of professional drive technology. With a focus on electric motors, frequency converters, and geared motors, we are active in both the national and international markets. On this page of our worm gear online shop, you will find a selection of EV and CMRV worm gears/motors with various speeds, specified in rpm, 1/min, and u/min. Since there are many different types and options available for worm gear motors, we have included some product examples below:

Worm gear with brake motors and special paint finish (red)

Worm gearbox with three-phase motors, plug-in shafts, torque arms and special paint finish (purple)

Worm gear unit with electric motors, output flanges and special paint finish (green)

Worm gear unit with motors, double output shafts and special paint finish (petrol)

Design and performance specifications of worm gears

Our worm gears, also often referred to as right-angle gearboxes, are available in sizes 30, 40, 50, 63, 75, 80, 100, 125, and 150, with power ratings of 0.12 kW, 0.18 kW, 0.25 kW, 0.37 kW, 0.55 kW, 0.75 kW, 1.1 kW, 1.5 kW, 2.2 kW, 3.0 kW, 4 kW, 5.5 kW, 7.5 kW, and 11 kW. These aluminum worm gears are available with the following hollow shaft diameters: 14 mm, 18 mm, 20 mm, 25 mm, 28 mm, 30 mm, 35 mm, 40 mm, 45 mm, and 50 mm.

Worm gear motors/special design

We also offer worm gear combinations with special motors that meet your specific requirements. We are the ideal partner for you in this regard, because with decades of experience and our own final assembly, we can cover a wide range of options: worm gears with brake motors, special shafts, grill motors with gearboxes, special voltages, special paint finishes, as worm gear motors, or in explosion-proof versions.

Technical design of geared motors

Worm gears consist of a shaft with one or more helical threads, the worm, and a helical gear wheel within it. The axes of the two are offset by 90°. Such a gear is particularly suitable for applications requiring high reduction ratios in a single step. Both left- and right-hand worm gear motors are available. Both directions of rotation are possible. Complete mounting flexibility includes foot, flange, and centering solutions with a torque arm. The motor terminal box can be mounted around the motor in 90° increments. The gear motor can be installed in any required position, such as horizontally or vertically. Due to the high interchangeability of the gear motor components (IEC flange), customers benefit from versatile options, reduced costs, faster delivery times, and easy maintenance. Worm gears are available in various speeds, from 2 to 600 rpm (revolutions per minute). Six sizes with center distances of 30–125 mm and gear ratios of 5–110 (up to i = 3000 when combining two gearboxes) are available in numerous configurations. The worm gearboxes and worm gear motors presented here were developed for universal use in general machine and plant engineering. The die-cast aluminum housing offers high strength despite its compact dimensions and low weight. Machining on all sides in a single setup allows for maximum precision and thus reliable application in many areas of drive technology. The high-quality gear set consists of a hardened worm with a ground profile and a wear-resistant bronze worm wheel, which is permanently cast to a cast iron hub.
