60K RPM Battery SPEEDER by SycoTec
SycoTec developed the revolutionary high-frequency spindle Speeder 60 ER11, which enables HIGH-SPEED MACHINING ON ANY CNC MACHINE - WITHOUT COSTLY CONVERSIONS. The fully autonomous spindle requires no external controls and impresses with tool magazine capability for automatic tool change. The Speeder 60 ER11 combines all the necessary components, making installation simple and commissioning fast. This powerful solution promises high efficiency and ease of use – a real advance in CNC machining technology. PLUG AND PLAY This system was developed as a user-friendly plug-and-play solution. At the center is a motor spindle with impressive specifications: It reaches speeds of up to 60,000 rpm and offers a power output of 300 to 500 watts. In addition, the system scores with maintenance-free hybrid ball bearings and an efficient ER11 clamping system.

Their robust Stainless-Steel spindle body sizes ranging from 25mm O/D to 60mm O/D with other sizes and variants soon to join their range. Their Latest Innovative product to launch here in February 2025 is the SPEEDER Spindle. Special features being; Out of the box application, No special adaption required. Tool Magazine and Auto Tool Change Compatible, Quick change long life battery operation, No cables, No Connectivity, fits most machine styles. Typical applications are seen within Dental, Optical and Engraving sectors through to key Industries of our time ranging from PCB and Chip dicing, Automotive and industrial Robotics, Simple and multi axis special purpose machining. Worldwide the growth markets are seen to be Dental CAD CAM and medical automation. SycoTec was renamed in 2006 from it's former owners KAVO originally formed in 1909.

SycoTec Custom Electric Motors
SycoTec produces a wide range of motor components operating as asynchronous motors, synchronous motors and/or as generators, with all key parameters being flexibly tailored to your requirements. We offer solutions within a wide operating envelope from 5W to > 600 kW and from 3 Ncm to 800 Nm. Beyond that, however, there are no limits to your specific parameters (subject to the laws of physics). In addition to creating customised configurations, we place immense value on optimising our processes. This is why we manufacture your components using the most suitable materials and the most cost-effective production methods. We look forward to working on your project.

Motor Inverters & Drives by Sieb & Meyer
Our partnership with Sieb & Meyer, a renowned name in high-speed drive technology, allows us to offer you frequency inverters that are not just components but pivotal tools for optimizing your machinery's efficiency, precision, and longevity. With the ability to operate motors at speeds up to 480,000 rpm and advanced control algorithms like pulse amplitude modulation (PAM), Sieb & Meyer drives offer unparalleled control over motor torque and speed. The drives support asynchronous and synchronous motors without sensors or with various encoder types providing solutions that push the boundaries of what's possible in automation and control. Designed for the rigors of industrial applications, these drives are built to last, with features like active power factor correction and wide input voltage ranges to accommodate different global standards and environmental conditions. Our Expertise in Drive Selection and Application This translates into energy savings, reduced wear on machinery, and significantly improved product quality. Customized Drive Selection: We work closely with you to analyse your project's specifications, from the type of motor and expected load to environmental considerations. This detailed approach ensures that the frequency inverter you choose is not just compatible but optimized for your specific use case. Setting up a drive for peak performance isn't just about connecting the wires. It involves understanding how the drive interacts with your machinery. We assist in configuring parameters to match your operational needs, ensuring smooth, efficient, and reliable operation. Should you encounter any issues post-installation, our support doesn't end at the sale. We offer troubleshooting assistance to resolve any control or performance discrepancies swiftly, minimizing downtime and maximizing productivity.
