Tubular linear motors from Dunkermotoren

The devices come with an integrated amplifier and controller option which the company says eases integration and simplifies wiring. They also feature a range of analogue and digital inputs and outputs, with CAN, Profibus and EtherCAT communications protocols available as standard. The controllers are capable of velocities up to 5ms and accelerations up to 422m/s2, with a maximum stroke length of 271mm and a peak available force of 92N. The motor's actuator rod can be supplied with a range of industry standard fixtures and fittings. Built-in feedback eliminates the need for expensive external encoders and offers absolute accuracy of ±350µm with ±12µm repeatability.
