Linear motion technology from Nippon Pulse is used in a wide variety of applications and industries. Linear solutions from NPM are offered in three basic formats: Linear Stages, Linear Servo Motors, and Linear Stepper Motors.
Linear motors come in a variety of technologies and styles, including brush or brushless, and configured as flat iron-core, U-shaped, or tubular. Nippon Pulse’s tubular Linear Servo Motor consists of a magnetic shaft and coil assembly (forcer) which can be integrated into a mechanical assembly and driven with a brushless DC servo drive. These linear motor actuators can replace ball and lead screw, pneumatic, and conventional flat or U-Channel linear actuation systems.
Linear Servo Motors from NPM can be found inside our Linear Stages and provide the force of motion. The force output of a linear servo motor is determined by two factors: the diameter of the shaft and the size and quantity of forcers. With shaft diameters ranging from 4mm to 100mm and stroke lengths from 20mm to 4.6m(!), NPM’s linear servo motors can tackle applications across nearly any industry.
With a linear servo motor solutions from Nippon Pulse, unique motion applications can be solved!
In this example, four fully independent forcers all move on the same axis (each forcers incorporates its own encoder head)
Linear Stages from NPM are fully assembled motion solutions with high degrees of capability. Capable of high speeds, high accuracy, and surprisingly high force output, NPM Linear Stages are capable of covering an extremely wide range of applications. Every NPM linear stage includes a linear servo motor, a high-accuracy encoder, and a linear rail — all sized to your specific application requirements.

NPM Linear Servo Motors
Nippon Pulse offers customized linear servo motor solutions.
- Simplicity – The simple structure of a magnetic shaft and coil assembly (forcer) experiences minimal wear and is entirely maintenance-free, keeping your
machinery running longer with less downtime and a significant cost reduction throughout its lifespan. - Precision – With no iron in the forcer or shaft, ultra-high precision is achievable with zero cogging for applications that require extreme smoothness of
motion in machine operation. - Accuracy – High-performance positioning with encoder resolutions less than 10nm enable a positioning accuracy of ±1.2 pulses of encoder resolution for
improved yield of high precision processes. - Strength – Rare-earth magnets, the strongest magnets available, add to the intensity of the magnetic field and thus allowing a small amount of current to
produce large amounts of force for low power and high efficiency machines. - Speed – Able to efficiently move large amounts of weight accurately and smoothly at high speeds, increasing throughput and profitability.
