July 16, 2007 - Nippon Pulse Motor introduces the Captive LINEARSTEP Series: Linear-Type Stepper Motor, a RoHS compliant, linear-type stepper motor with a one-piece captive shaft.
The guideless, linear shaft movement gives designers a simple linear stepper system at a fraction of the price of a conventional rotary stepper system that must be adapted for linear motion. The anti-rotation cap allows the shaft to actuate without an external guide mechanism that is required with non-captive type linear stepper motors.
The Captive LINEARSTEP produces linear motion in a rotary size package with outside dimensions of 25mm and 35mm, and a 30 mm stroke. Shaft travel in resolutions from 0.010 mm to 0.05 mm per step can yield up to 5 Kg of force. The same drive circuit used for NPM tin-can type steppers can drive the Captive LINEARSTEP.
The Captive LINEARSTEP has ball bearing shaft supports and a welded motor case that ensure long life and durability. The one-piece shaft could eliminate some misalignment issues caused by two-piece shafts.
These new linear actuators give OEMs an opportunity to reduce device components and simplify design. Designers can replace rotary systems that generate complicated linear movement through belts and pulleys or rack and pinions. This can result in smaller space requirements and ultimately lower system costs.
Nippon Pulse offers various controllers (boards and chips), drivers (boards and chips), and motors (tin-can and linear servo) to cover almost any motion application. (See attached file: PFCL25 captive type small.JPG)
