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 […]

Nanometer Precision 3-Channel Controller for miniature piezo inertia drives & actuators
PI L.P.,announces the newest digital servo controller with 3-channels, offering greater flexibility for miniaturized precision positioning and handling tasks. Applications include precision alignment and automation, semiconductor technology, photonics, bio-nano-technology, metrology, microscopy, micro-manipulation. The new E-873.3QTU 3-axis controller compliments the size of the ultra-compact positioners it controls, has integrated power amplifiers and interpolator, and is macro […]
New voice coil actuator delivers low hysteresis/low friction
For some applications, inconsistent motion caused by excessive friction is simply not an option. BEI Kimco has developed a new Linear Voice Coil Actuator (VCA) that provides extremely low hysteresis/low friction with precise and consistent bi-directional position control. Initially designed to meet the exacting requirements of an anesthesia machine, the new LAH15-19-000A VCA will serve […]
Miniature voice coil actuators
H2W Technologies offers miniature versions of both moving coil and moving magnet voice coil actuators. Plus the company offers custom designed solutions to meet application specifications. H2W has built its smallest moving magnet voice coil actuator (NCM01-04-001-2IB) to date, with an outside diameter of 0.40 in. — 10 mm — and a length of 0.735 […]
