SEW-EURODRIVE GmbH & Co KG

Description

The new precision servo gear units PxG® were developed for use in a large variety of applications. They stand for top quality and technical innovation in the detail. A comprehensive modular system allows for the flexible adaptation regarding torque, gear ratio, output geometry or the interface to the servomotor. Exclusive individual elements such as the “Premium Sine Seal” oil seal, the use of SEW GearOil or the bearing system ensure a long service life, even under extreme loads.

From the modular system, three preferential series can be outlined as series of performance classes 5 to 7. Each series follows different requirements. Performance class 5 focuses on the use in dynamic motion sequences with a large number of acceleration and braking processes in intermittent duty. Performance class 6 is suitable for applications with high cyclic duration factor. A service life of 30,000 h can be achieved by modifying gearing and bearings as well as the use of a bellows coupling. The use of performance class 7 is optimal if space is at a premium. Maximum precision is achieved here already in the standard version by a rotational clearance of 1 to 2 angular minutes.

Innovative production and assembly processes ensure shortest delivery times and constant product quality. The relevant data of the final checks is attributed to the real product in the digital twin. Besides providing comprehensive documentation packages, this also enables improved simulation of the planetary gear units in the life cycle at a given gear unit utilization. The wear resistance reached in gearing secures operation through minimum deviations compared to the delivery state – even after many load cycles.

Due to the high positioning accuracy, typical areas of application are a large number of handling applications in the fields of robotics, automation and handling technology as well as machine tools and woodworking machines. The compact design and durability in continuous duty make these gear units ideal for use in food, packaging, printing, paper and textile machines.

MOVIGEAR® performance

MOVIGEAR® performance

Within the modular automation module set MOVI-C® the mechatronic drive unit MOVIGEAR® performance is the first product for decentralized installation, consisting of parallel-shaft helical gear unit, permanent magnet motor and integrated drive electronics in a single housing.

MOVIGEAR® performance with direct fieldbus connection is intended especially for the area of dynamic materials handling technology and speed-controlled axes up to positioning tasks. Communication takes place via fieldbus interfaces, such as PROFINET IO, EtherNet/IP™ and Modbus TCP, and the integrated digital inputs and outputs.

The new drive unit is characterized by its compact design and high overload capacity. By achieving the highest motor efficiency class IE5 according to IEC TS 60034-30-2 and maximum system efficiency in accordance withto IEC 61800-9-2, MOVIGEAR® performance surpasses all conventional solutions to date.

These new products expand the possible applications of SEW‑EURODRIVE's decentralized drive technology, which has proven itself an asset over the decades. To combine its benefits with those of the MOVI‑C® modular automation system, the decentralized drive systems have been developed on the basis of the MOVI‑C® portfolio. They complement the products released so far in terms of functionality and consistency.

Typical areas of application for the new product portfolio include the food and beverage industry, intralogistics and parcel logistics, and also the automotive industry and airports.

Servomotoren - Baureihe CM3C

Servomotoren - Baureihe CM3C

SEW-EURODRIVE is adding servomotors for high external loads to the MOVI-C® modular automation system. The new CM3C series consists of the sizes 63, 71, 80, and 100. The motors have standstill torques from 2,7 to 40 Nm. This compact range of servomotors with increased inertia are used in machines and applications where a low ratio of load moment of inertia to motor moment of inertia is desired for control reasons. In addition, there is an extensive range of possible options, such as brakes, a large number of different encoder systems and encoder interfaces, as well as flexible motor connection variants for adapting perfectly to the respective conditions of the customer application. The new series is also optionally available with single-cable technology using the newly developed, SEW-EURODRIVE-internal MOVILINK® DDI encoder interface, making wide-ranging digital integration possible. For example, an automatic startup is performed when motors are connected to SEW-EURODRIVE inverters. The encoder signals are transmitted digitally and the brake control system is also digital, with an option for monitoring the condition of the brake. To provide customers with the greatest possible degree of flexibility in their system, the CM3C motor will be offered in future both with standard SEW-EURODRIVE encoder systems and also with DRIVE-CLiQ, EnDat 2.2, and HIPERFACE DSL® encoders. As is usual for SEW-EURODRIVE, the motor series offers a diverse range of options. When combined with the Bruchsal-based company's modular gear unit system, the possibilities are almost endless. One key unique selling point is the availability of two brake versions. Alongside the 24 V holding brake typical for servomotors, there is also a brake with increased working capacity for applications where service braking or emergency braking is required. In combination with the single-cable technology, there is also a new smart brake rectifier for the brake's AC connection. This is current-controlled and can cope with a wide range of input voltages from 100 to 500 V. Typical areas of application include machine automation, handling gantries, and trolley drives.
