H2W introduces its most compact moving magnet actuator with a hole through the shaft. The voice coil actuator can be operated under either open or closed loop position control and is ideal for controlled sinusoidal motion applications (1 to 1000 Hz for open loop applications and 1 to 125 Hz for closed loop applications). The NCM moving magnet type linear actuator has a precision ground 0.125” diameter shaft that is guided by precision manufactured high cycle low-wear plastic bushings. The shaft has a 0.059” hole that goes through the shaft which is ideal for routing a fiber optic cable, passing light through, or routing an air hose for vacuum or pressurized air.
The moving magnet voice coil has a 0.10" [2.5 mm] stroke, generates 0.1 lbs [0.5 N] of continuous force and 0.3 lbs [1.3 N] of peak force. The actuator is driven in open loop mode by feeding a sinusoidal control signal into a servo amplifier which is in turn connected to the two leads of the actuator.The actuator can also be operated as a closed loop system by adding a programmable motion control and position feedback device.
