Nippon Pulse now offers a new series of motors to its extensive line of Linear Shaft Motor servomotors. The SX series features high-energy magnets for greater force in mid-range sizes, to supplement the existing sizes of the standard S-series motors. The SX series motors are available in 6, 8 and 10mm shaft diameters. Each size […]

Linear shaft motors see increased force capabilities thanks to advances in magnets
By Paul Denman • Applications engineer and business development • Nippon Pulse America Today most linear-motion designs execute their strokes with actuators based on stepper motors or brushless dc (BLDC) servo motors. Such designs have an inherent complexity due to the fact that the motors and its gearing and encoder must essentially hang off the […]
Linear guides, power transmission, actuators see unexpected applications
Our 2020 survey of the industry indicates an unabated trend towards more automation of previously static or manually tended systems. Key to these new offerings is installation simplicity for OEMs and end users of linear components for linear axes … as well as positioning stages and Cartesian robots. In fact, Cartesian robots (also called linear […]
New 20-mm linear stepper motor now available from Nippon Pulse
Nippon Pulse now sells the the PFL20 Linearstep — its smallest linear stepper motor yet. The PFL20 is a highly efficient, high thrust tin-can linear actuator with a 20-mm diameter and a bipolar winding. PFL20 is RoHS-compliant, has a 30/60-mm effective stroke, and can reach 6 N of force at 200 pps. With 24 steps […]
Can-stack linear actuators: How the motor and screw components work
Can-stack linear actuators are one type of stepper-motor design that converts rotary to linear motion with a built-in leadscrew. The linear actuators incorporate can-stack motors — sometimes called claw-tooth step motors, tin-can stepper motors, or claw-pole motors — leverage low-cost construction with punched sheet-metal parts that form toothed (or clawed) cups surrounding bobbin coils. Common […]
Podcast: Scott of Nippon on iron core, U-channel, and tubular linear motors
In a recent Technology Tuesdays podcast, Brian Scott, application engineer at Nippon Pulse America, talked to me a little bit about linear motors including iron core, U-channel, and tubular linear motors … and the benefits and drawbacks of each. He also shed some light on the major design objectives OEMs cite when migrating axes to linear motors. Click here […]
Nippon Pulse small-forcer linear servo motor for high-density applications
Nippon Pulse America Inc. now sells one of the smallest available linear motors for high-density applications — the L250SSS Linear Shaft Motor. It is a 25-mm-diameter linear servo motor with a single winding and our smallest available forcer – only 30mm in length, and with higher force than competing off-the-shelf motors. Its maximum usable stroke reaches to […]
How linear force-current relationships from linear motors improve motion
Applying an electric motor is easier when one knows what it will output for a given input. The simpler it is to predict that, the more elegant and robust the design. To this end, some linear motors have linear force-current relationships so engineers don’t need to accommodate nonlinear effects through approximation or additional terms in […]
