Hexapods are 6 DOF motion systems that derive 6-axis movement (XYZ, Pitch, Yaw) from actuators placed in parallel between a top and bottom platform. Available in a variety of sizes with bases ranging from 100mm to 1m, different stiffness configurations, and supportive of loads from 2 kg to 1,000+ kg, PI hexapods share two common […]

PI, a leader in piezo ceramic and motion control solutions, offers value added piezo components by adhering […]
Voice coil actuator basics
Voice coil actuators are a type of direct drive mechanism that provides extremely precise positioning over small displacements. Like linear motors, they work on the principle of a permanent magnet field and a coil winding. When a current is applied to the coil, a force is generated. This force, known as the Lorentz force, is […]
