NEW SERVO MOTOR WITHSTANDS WASHDOWN ENVIRONMENTS
New from Kollmorgen is the versatile and durable AKMA servo motor. With its lightweight design and high torque density, the motor is suited to precision motion applications in food & beverage processing, and in pharmaceutical & medical packaging operations. The motor has a hardened anodized aluminium surface which
ensures a cost-effective hygienic option to stainless steel in medium- to heavy-washdown applications. This offers strong resistance to chemicals across a wide pH range and, as it is scratch resistant and will not flake like a painted motor, it can be used above the food line. The AKMA’s IP69k rating enables it to deliver high performance even
in wet and rugged environments, supporting critical applications like tracking and positioning for antenna pedestal systems. In addition, its stainless steel shaft meets functional safety requirements, while its ‘one- piece’ rounded housing structure eliminates the need for a seal between the flange and housing to prevent puddling and water ingress. Its vented design equalizes pressure inside and outside for increased OEE
and motor durability.

ETHERCAT MOTION CONTROL SOLUTIONS FOR A RANGE OF APPLICATIONS
Mclennan works closely with distribution partners that have developed EtherCAT motion controllers, stepper and servo motor drives, digital and analogue I/O modules and feedback devices. Through its in- house design and build capability, the company integrates these products with mechanical components such as actuators, gear units and positioning stages, etc. to provide complete, ready to install, motion-centric sub-systems. These are used in areas such as packaging machinery, medical devices, pharmaceutical test and production equipment, scientific research and many more. One example is the Flex-6-Nano from Trio Motion. This is a powerful
integrated EtherCAT servo and stepper controller for high-speed synchronised motion and machine control with cycle times as low as 125 microseconds. Its modular construction allows from two up to 64 motion axes and the din-rail mounted system also takes care of machine I/O and supplementary motion through Trio’s modular Flexslice 16 in/out digital, analogue and axis modules. The multitasking operating system includes setup and diagnostics from Trio’s Motion Perfect software with programming using the TrioBasic motion language or through IEC611-31. A comprehensive motion library includes electronic gearbox, axis interpolation, maths functions, robotic kinematic transformations and more. Where open loop control is satisfactory and EtherCAT is preferred, Mclennan uses solutions from its USA-based distribution partner, AMP Inc. (Applied Motion Products). Its STF series microstepping intelligent drives are available for up to 10A per phase with compatible stepper motors. A choice of Ethernet interfaces including EtherCAT allows streamed motion commands from the host controller. Alternatively, or in combination with the streamed commands, stored programs on the STF can called from a host-controller using daisy-chained, dual port communications, to realise medium level multiple axis synchronisation. The panel mounted STF series also include a compliment of eight digital inputs and four digital outputs to provide local control of machine functions. Servo motor solutions from AMP include EtherCAT communications options for its innovative SS series StepSERVO closed loop intelligent drives. AMP’s StepSERVO closed loop technology offers greater torque, acceleration and throughput than traditional step motor systems. The SS-EC is a panel mounted drive with continuous output current of 3, 5 or 10 Amps and is supplied with a choice of 14 matched StepSERVO stepper motors from NEMA size 11 to 34. AMP’s SS-EC series drives support CANopen over EtherCAT (CoE) for tight axis synchronisation through CiA operating modes that include profile cyclic synchronous position and cyclic synchronous velocity, as well as profile velocity, torque and position. Another partnership is with JVL Industri Elektronik. JVL’s integrated
servomotor and stepper motor products are intelligent drives that combine motor, drive and optional feedback as single housed packages complete with a motion controller, machine I/O and a power supply. JVL’s Quickstep and ServoStep integrated stepper motors and MAC motor series integrated servo motors are available with the CiA402 drive profile for its EtherCAT protocol option. This brings support for EtherCAT synchronised position (CSP) and synchronised velocity (CSV) modes which potentially means millisecond-level motion and machine synchronisation with extremely low jitter for demanding high-speed automation tasks. Other modes such as profile position, profile velocity and homing are also supported. JVL’s MAC motor integrated brushless servo motors are available for motor power to 13.5kW peak, and its ServoStep integrated stepper motors cover torques to 25Nm. Mclennan also works with Leine & Linde, the Swedish manufacturer of
advanced measuring systems. Its 600 and 900 series absolute encoders now include EtherCAT communication options that are able to provide ultra-fast position read and processing values, with increments as short as 31.25 microseconds.
