November 9, 2012 - Suited for controlled sinusoidal motion applications, Model NCM02-05-005-4JBH operates from 1–1,000 Hz for open loop applications and 1–125 Hz for closed loop applications. Precision ground 0.125 in. diameter shaft, guided by jeweled sapphire bushings, has 0.070 in. hole, which is suitable for routing fiber optic cable or air hose. Featuring 0.15 in. stroke, non-commutated, moving magnet type linear actuator generates 0.5 lb of continuous force and 1.5 lb of peak force.

Santa Clarita, CA, 91350

Press release date: November 5, 2012

H2W introduces its most compact moving magnet actuator with a hole through the shaft.  The voice coil actuator (NCM02-05-005-4JBH) 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 jeweled sapphire bushings.  The shaft has a 0.070” 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 0.15" [3.8 mm] stroke, generates 0.5 lbs [2.2 N] of continuous force and 1.5 lbs [6.6 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.

- High frequency operation
- High acceleration
- Compact size
- Custom strokes and force configurations available

H2W Technologies is dedicated to the design and manufacture of linear and rotary motion products that are used in the motion control industry.  The complete line of linear electric motors includes: single and dual axis linear steppers, DC brush and brushless linear motors, voice coil actuators, and AC induction motors.  Also offered is a complete line of ball screw, lead screw and belt driven positioning stages.  Other motion control products include: limited angle torque motors for compact, limited angular excursion rotary servo applications, 3 phase brushless rotary servo motors with matching digital servo amplifiers and permanent magnet linear brakes for fail-safe, zero power braking for baggage handling and people moving applications as well as amusement park rides.
