H2W Technologies Voice Coil Positioning Stage VCS08-350-LB-01-MCS

Voice Coil Linear Positioning Stages are designed for a variety of short stroke and high velocity applications. They have a stroke lengths of up to 2.0 in. (50 mm), a continuous forces as high as 100 lbs (445 N) and a peak forces of up to 300 lbs (1335 N). They are ideal for short stroke closed loop positioning applications where intricate position, velocity, and acceleration control is necessary. They have a compact size that allow it to fit into small spaces. The stages have very low electrical and mechanical time constants. The low moving masses allow for high accelerations of light payloads. The iron-less core coil assembly has no magnetic attractive force to the stationary magnet assembly, which reduces the load on the bearing system, which increases the life of the bearing. There are no magnetic drag forces (hysteresis), which allows for higher accelerations. These actuators are wound in such a way that no commutation is required for motion to occur. Electrical devices such as Hall Effects are not necessary. The result is a much simpler and more reliable system.
