Linear Shaft Motor (PSM Series)

  • Linear Shaft Motor
  • Peak force up to 513N, Continuous force to 102N
  • Ideal for high precision/smooth motion

Conventional Ballscrew Form Factor Shaft Motors For Precious And Efficient Linear Motion Systems

PBA Linear Shaft motors were designed with similar form factor dimensional outline and Functionality to that of a mechanical ballscrew/nut with the intention to provide to equivalent upgrades to traditionally ballscrews and pneumatic cylinder applications.

The coils of the PSM motor surrounds the magnets allowing for optimal use of magnetic flux which makes the air gap non-critical and allows for max efficiency as the motor requires less current and mass to produce similar force ranges when compared to other brushless linear motors.

Resultant performance characteristics from the above design are precision positioning and Minimal speed ripple which makes the range of applications unlimited and highly diverse.

  • Zero cogging
  • Precise speed and positional capability
  • Low torque ripple
  • Simple economical construction
  • Compact and lightweight
  • Non-critical air gap
  • Easy upgrade of existing ballscrew systems
