Nippon Pulse – Linear Shaft Motor

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 Shaft 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.

Specification Overview

  • Range of shaft diameters: 4mm to 100mm
  • Stroke lengths: 20mm to 4.6M
  • Achievable peak forces more than 3000N
  • Continuous force up to 600N

Linear Motor Applications
The Linear Shaft Motor can be built for a variety of operating environments, including in water, vacuums, or clean rooms.

  • High-speed pick-and-place machines
  • High-accuracy pick-and-place or dispensing applications
  • Scanners that need smooth and precise movements
  • Long-life and low-maintenance expectations
  • Applications that require low power and high efficiency

Linear Motor 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.

Linear Motor 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.

Linear Motion 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.

Linear Motion 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.

Linear Motor Speed
Able to efficiently move large amounts of weight accurately and smoothly at high speeds, increasing throughput and profitability.
