REMAINING COMPACT ENOUGH TO FIT INSIDE A MOTOR A servo drive small enough to be placed onto a moving load – such as a robot, automated guided vehicles (AGV) or aerial drone – has been launched by Elmo Motion Control. Weighing just 20g and with a volume of less than 13cm3

a restricted space. Applications include automated production machinery, robots, AGVs, aerial drones, medical bionics and any application that requires high performance servo operation. The drive is certified to IEC 61800-5-2, SIL-3.

, the Gold Twitter Nano’s compact size

means it can be placed on the moving load, on the motor, or even inside the motor. This improves performance, saves space and reduces the need for cables. The new drive, therefore, is suitable for motion control applications with a high power demand in

The Gold Twitter Nano also offers advanced networking capabilities based on EtherCAT and CANOpen. The Gold Twitter range of servo drives uses Elmo’s fast and soft power switching technology (FASST), giving over 99 per cent efficiency and negligible electro-magnetic interference (EMI).


A brushless DC motor has been designed by Printed Motor Works for use in dynamic vehicle testing. The high power-density motor is part of a steering robot developed by Anthony Best Dynamics. The system helps provide a repeatable test environment for quantitative testing of road vehicles on the track. The compact design of the motor enables the

assembly to be mounted behind the steering wheel, allowing normal driver operation between tests. The three-phase permanent magnet motor is a customised version of PMW’s IR9 series. Its conventional internal rotor design combined with dovetailed NdFeB rare earth magnets gives it exceptional performance and long service life. Originally developed by Printed Motor Works (PMW) for an actuator in a bomb disposal robot, the modified motor retains the same winding specifications but incorporates a different shaft and a bespoke casing that integrates directly into the Anthony Best Dynamics steering robot. During the design process the two companies’ engineering teams worked closely together to ensure the exacting specifications of the motor package were met. Steering robots, or programmable steering controllers, apply precise, repeatable inputs to a test vehicle’s steering system. Applications include the development of advanced driver assistance systems (ADAS) and electronic stability control (ESC) systems, as well as self-driving cars and other autonomous vehicles. PMW

The Gold Twitter Nano 80A/80V demonstrates Elmo's approach of ‘cutting costs by technology,’ and supports advanced substrates. It can be used for structural bonding and sealing.

The new WLAN 1,100 wireless module from Phoenix Contact combines access point und antenna technology in just one device. In contrast to the classic concept, it is installed like an antenna directly onto machinery, mobile vehicles or control cabinets, rather than inside the control cabinet. Two integrated high performance antennae with MIMO

technology ensure reception wherever it is needed. This concept offers the user a cost-effective and extremely simple WLAN machine connection. As the wireless module does not require space in the

control cabinet it is simple to retrofit. It is attached using single-hole assembly, and via a Combicon connector and RJ45 Ethernet connector, as usual. The wireless module is also suitable for tough industrial environments. It is shock proof according to IK08 and therefore even withstands stronger mechanical loads.


Esterline Connection Technologies’ SOURIAU five- pin UTL range is simple to use and suited to applications that require field wiring. Engineered in compliance with IEC 60320, IEC 69184 and UL 1977, the five-pin is a must for new industrial facilities and field facilities. The five-pin UTL connector significantly improves tasks for operators working on aerial work platforms or in tight spaces. The rear coupling snaps onto the body of the connector whilst accommodating cable clamps and cable glands. The resulting assembly forms a rigid structure that protects cables from strain and vibrations and guarantees both the quality and reliability of power and signal connections. Metal tabs provided in the connector ensure an audible click that is both sensitive and instantaneous. Robust and safe for users, the push-pull lock and

thermoplastic construction of the plugs and receptacles ensure safe use. 36 JUNE 2017 | DESIGN SOLUTIONS

A renowned manufacturer has relied on the tried and tested ROBA-stop-M-safety brakes by mayr power transmission in its new storage and retrieval systems. One ROBA-stop-M safety brake by mayr power transmission is installed directly on each upper and lower toothed rack of the storage and retrieval system. These electromagnetic safety brakes work according to the fail-safe principle. In case of error conditions such as power failure and emergency stop, these ensure that the respective storage and retrieval system stops reliably within the shortest possible time. ROBA-stop-M brakes guarantee full safety even if the drive is dismantled, for example for installation or maintenance work. In addition, the safety brakes by mayr power transmission score crucial points

with regard to operational safety and ease of maintenance in comparison to many other safety brakes. They distinguish themselves through an enclosed constructional design and the high Protection IP54 or IP65 in sealed design. Designed for a duty cycle of 100 per cent, the ROBA-stop-M brakes are maintenance-free for the service lifetime of the friction linings. Their compact and functionally safe construction enables quick and cost-effective installation. Installation and adjustment errors can be avoided thanks to the design-specific, tested and non-changeable working air gap. Furthermore, the variable spring configuration for different

torques makes the safety brakes particularly flexible.
