29 www.drivesncontrols.com February 2020 SPS REPORT n Allied Motion launched a new range of outer-rotor brushless DC motors supplied as frameless stator-rotor part sets. The KinetiMax HPD motors come in six frame sizes and three stack lengths, and offer low cogging torques, high peak torques, high torque-to-weight ratios, and efficiencies of 83–90% over a wide speed-torque range. Baumüller was showing a new generation of its b maXX 5300 frequency converters which no longer use plug-in safety modules, but have integrated safety functions instead. The drives support the FSoE (FailSafe over EtherCat) standard, allowing several axes to collaborate safely and to work with higher-level safety controls from various manufacturers. Using resolvers, speed resolutions of better than 1 rpm are possible. When triggering the STO safety function, the controller is switched without torque with a delay of less than 1ms. Bonfiglioli has added a compact 15kW variant to its Agile series of frequency inverters, designed to be customisable to the application and users’ requirements. It has HVAC functions and can drive asynchronous AC motors or brushless PM synchronous machines. Delta Line was demonstrating an expanded series of Portescap’ s Ultra EC brushless, slotless DC motors in diameters from 16-35mm, with continuous power ratings from 27–330W. There are three variants optimised for parameters such as high speed, high continuous torque, or a balance of speed and torque. Kollmorgen was showing a second generation of its AKM2G servomotors with higher power densities and more torque from a given size, allowing some machines to use smaller motors. A second generation of Kollmorgen’s AKD2G servodrives offer new safety functions which can avoid the need for I/O modules, thus saving space. Maxon motor has a compact new drive that combines its EC-I brushless motor with an EPOS4 positioning controller, with the option of a planetary gearhead. The efficient, IP65-protected IDX drive has configurable analogue and digital inputs and outputs. The EPOS4 is now also available in a micro version (the Micro 24/5) suitable for applications such as robotics where space is tight. Nord Drivesystems demonstrated its recently announced “IE5+” permanent magnet synchronous motor which can be supplied without a fan and with smooth surfaces. It is said to have much lower losses than IE4 motors, and will be available initially in power ratings from 0.25–1.1kW, with continuous torques from 1.6–4.8Nm, and operating speeds from 0–2,000 rpm. Nord has also improved the design of its IE3 asynchronous motors with optimised fans and fin shapes for better heat dissipation. Panasonic has developed a 400V servodrive system especially for the European market.
