SEW-Eurodrive has released Movigear B, the latest extension to the company’s Movigear family of all-in-one decentralised mechatronic drive systems.
The B series comprises motor, gear-unit and drive electronics in a single, compact housing. Additional features such as four communication options, new safety functionality and a specific wet area variant, make it one of the most versatile decentralised drive solutions on the market.
“The new Movigear B range incorporates a permanent-field servomotor, highly efficient gearings and new electronic components with intelligent control mode,” says Paul Strzalkowski, electronics product manager for SEW-Eurodrive. “The result is a mechatronic drive that is able to deliver up to 300% start-up torque with optimised constant speed power consumption. End users can expect energy cost savings as high as 30% compared to traditional solutions, making this a cost effective drive option for conveyor applications across a wide range of industries.”

The unit is offered with various communication variants including direct binary communication, AS-Interface, single line network installation and SBus. “The extended choice of communications allows users to implement decentralised drive applications across a range of topologies,” comments Strzalkowski. “This provides industry with optimised installation and operational flexibility.”
Featuring a hygienic housing the drive is ideal for food and beverage applications. “The totally enclosed design prevents debris build up and also serves to reduce noise,” says Strzalkowski. “A special ‘wet area’ variant with anti-stick surface coating is also available, making this an ideal solution for applications where hygiene is important.”
The series is equipped with ‘safe torque off’ (STO) integrated safety functionality as standard, designed to SIL 3 according to IEC 61800-5-2. This guarantees that torque cannot be generated when the STO input is activated.
Movigear B is offered in two torque ranges, 200 and 400 Nm, and is available in a choice of keyless TorqLoc or keyed hollow-shaft mounting systems. All variants are equipped with digital inputs and facilitate local manual operation. Additionally, an optimised interface between motor and gear unit offers inherent energy efficiency.
