The data will also be sent to the system is in use in the offices of Callaghan engineering firms to enable rapid determination in Wellington and Christchurch and provides of the health of the buildings after a severe warning of earthquake shock waves before they shake. arrive, switches off/on emergency systems, triggers visible and audible alarms. This enables staff to potentially exit the building before the destructive wave arrives. Data from the system is sent to a central server, Jenlogix hosted by Red Wolf in its secure data centre, for Phone: 09 579 6439 | sales@jenlogix.co.nz processing. www.earthquakeearlywarning.systems/ Maxon motor Australia has configured a combination of brushed DC motor, planetary gearhead and digital incremental encoder with completely customised features for a prominent medical manufacturer and have produced it in 11 working days. An interactive 3D model of the entire assembled combination showing all modifications and final production part numbers can now be generated within an hour of specification request along with data sheets showing the working points of the application. The new motor has a unique stepped planetary gearhead that uses a 26mm diameter on the highspeed input stage and a 32mm on the high torque output stage. Focusing the wear and strength attributes by placing components specific to their role also increases the motors power density. In order to allow for the full use of shaft length that is tailored for the application, a new process of laser welding the inner race of the output bearing directly to the shaft material has been used over CUSTOMERS SPOKE, LEONARD PRODUCTS LISTENED In response to customer requests for increasingly complex rolled and pressed products, Leonard Products invested. Complementing the current section and rolling operations in the workshop, Leonard Products has invested in new high precision cut, roll and folding equipment. With the addition of the brand new Durma 300 tonne CNC controlled press brake and Durma plate rolling machine, Leonard Products will continue to provide high quality finished steel products into the market. Investment in new technology has allowed the company to increase the range of cut, bend, rolling and punching options, in an ever-increasing range of materials. Leonard Products can cut acrylic, polycarbonate, MDF, timber, plywood, cardboard, and many other textiles as well as various metal products (aluminium, mild and stainless steels). “We will continue to listen to customers and strive to exceed their expectations,” says the company.

The motor is capable of producing over 10,000rpm and the gearhead up to 12Nm with ratios to 1526:1. Zero cogging and linear characteristics combined with new encoder resolutions up to a staggering 65,536cpt open new position control possibilities for automation, tool and robotics applications. www.maxonmotor.com.au MAXIMUM POWER DENSITY DC MOTOR
