Zubax in Estonia Develops Electro-Permanent Magnet for Aerospace & Robotics 

Zubax Robotics of Estonia has added a new product to its electro-permanent magnets portfolio designed for aerospace and automation applications. The EPM4 combines the advantages of electromagnets and permanent magnets by being able to switch between the on-state and off-state on demand, like an electromagnet, while consuming zero power in either state, like a permanent magnet. 

Applications include payload attachment in aerial vehicles; workholding in CNC machines, manipulators and robots; also in magnetic locks, clamps and holders. In concert with the company’s focus as a developer of products for both manned and unmanned aerospace systems, the device supports advanced communications interfaces such as Cyphal/CAN FD control with diagnostic telemetry, RCPWM control input and voltage level control input. 

Zubax is a research and development company that specializes in manned and unmanned aerospace systems, chiefly involving energy-efficient electric propulsion and real-time intravehicular data distribution. It founded the OpenCyphal project to address the challenge of on-board deterministic computing and data distribution in next-generation intelligent vehicles. The standard is now used by numerous vendors and companies for manned and unmanned aircraft, spacecraft, micromobility, even racing cars. 

Complete UAV powertrain kit from Zubax includes motor, controller and propeller for drones 

Based in Tallinn, the company’s hallmark product is the Telega system which provides sophisticated control of permanent-magnet, synchronous-magnet and brushless DC motors for aerospace and robotics. It also builds a complete electric propulsion system for drones. 

Its Myxa ESC is a high-end PMSM/BLDC motor controller for propulsion systems in light unmanned aircraft and watercraft that is based on the Telega motor control technology. Applications include propeller and fan drives in drones, pump and propeller drives in unmanned watercraft, also fuel pump drives for jet engines and gas turbines. For more info, see www.zubax.com
