SEW EURODRIVE Introduces New CM3C Series Synchronous Servomotors

November 12, 2021

SEW Eurodrive CM3C 1 400

Highly dynamic, high-precision and high-performance drives are essential wherever heavy external loads need to be moved quickly and positioned exactly. CM3C synchronous servomotors combine precisely these features and are also exceptionally compact and space-saving.

The lowest possible ratio of load moment of inertia to motor moment of inertia is key for transporting heavy loads from A to B at high speed and with great precision. CM3C series servomotors thus boast increased inertia. The synchronous motors are therefore particularly suited to all automation, handling, and transport applications for heavy goods with a correspondingly high mass moment of inertia. With their four sizes – 63, 71, 80 and 100 – they can cover standstill torques from 2.7 to 40 Nm.

The servomotors are also exceptionally small and space-saving, while the option of mounting gear units to the motor directly eliminates the need for adapters and couplings. Short-term overload capacity and smooth surfaces (hygiene-friendly design) make the medium-inertia servomotors particularly robust and dust-repellent. In addition, the rotors, which are equipped with permanent magnets, deliver a very high level of efficiency, thus ensuring exceptionally energy-efficient operation.

Flexibility and reliability are also key features of the brakes available for the servomotors. Alongside the 24 V holding brake typical for servomotors, users can also choose an optional brake with increased working capacity. Thanks to this equipment, the synchronous motors can even handle applications where emergency braking is needed. Requirements of this kind are typical in machine automation, handling gantries and trolley drives.

Thanks to our modular system, the highly flexible CM3C series servomotors can be adapted to meet specific needs. At the same time, single-cable technology means they can be installed quickly and integrated intelligently into state-of-the-art Industry 4.0 concepts.

Put to the Ultimate Test – Part 1: Torsion Tests by HELUKABEL

DCS Put to the Ultimate Test Part 1 Torsion Tests by HELUKABEL 1 400x275

Cables and wires in industrial robots and other moving machine parts are often required to withstand extreme stresses caused by torsion. Constant repetitive movements put materials under considerable strain. At the same time, operators expect components to function perfectly and reliably throughout their entire service life to avoid disruptions, outages and safety hazards.

For this reason, at HELUKABEL, we simulate intensive and continuous torsion stresses under realistic conditions with our high-tech testing equipment in Windsbach. We have several types of apparatus for doing this because some of our customers, for example those in the automotive industry, have very precise specifications for how a torsion test is carried out. The tests show that our cables and wires withstand speeds up to 1,000°/s, accelerations up to 2,000°/s² and torsion angles up to 720°. Hence, we make sure that each product always meets our customers’ high standards, and that they receive the impeccable quality they rightly expect from us as a leading supplier of cables, wires and accessories for more than 40 years.
