PI (Physik Instrumente) has recently expanded its portfolio, in total, three variants of the PIMag® voice-coil linear drives are now available. They are best suited for travel ranges up to 10, 15 or 20 mm and reach velocities up to a maximum of 750 mm/s.
An integrated optical linear encoder for direct position metrology ensures reliable position control and repeatability with a resolution of up to 0.01 µm. Because the feed force of the magnetic direct drives depends on electrical current, it is not only possible to use the PIMag® linear actuators for motion, but also for generating force. In conjunction with the C-413 digital controller of PI, it is possible to perform tasks in automation systems that require fast, exact submicrometer positioning and controlled actuator force, for example, when testing sensors or operating elements.
Thanks to their durability, linear drives are also suitable for industrial applications that need to be operated “around the clock”, seven days a week. The three variants of the PIMag® voice-coil linear drives include V-273 PIMag® Voice Coil Linear Actuator, V-275 PIMag® Voice Coil Linear Actuator and V-277 PIMag® High-Load Linear Actuator.
