The Benefits of Linear Motors

Linear Motors

Today, most motor technologies are set up to run in a rotary fashion. This can be a problem when the need to produce a straight move arises. To get linear output you would be forced to buy and maintain additional components (such as pinion gears, belts, pulleys, etc.), thus wasting precious time and money. To solve this issue, many engineers opt to upgrade their system to use a linear motor. Linear motors run in a straight line and follow your instructions, all with a minimal number of components. 

Performance Attributes of Linear Motors

  • Straight Motion
    • Up / down  
    • In / out   
    • Push / pull
  • Fast
    • Acceleration
    • Deceleration
    • Run speeds up to and beyond 100” per second
  • Precise
    • Positioning with closed loop encoders built right onboard
    • Motion profile to follow your exact commands (in, out, sine/cos, vibrate at desired frequency, etc.)
    • Drive the brushless linear motor with the right amount of current to get exact force needed
  • Robust
    • Simple two component construction - stator and rotor
    • Less components means less to fail = more engineering reliability
    • Non-contact magnet field creates motion
    • Long life bearing; require 1 minute of maintenance every 6 months

Moog's linear motors offer dynamic and precise linear motion positioning for robotics, factory automation, processing, packaging and other industrial applications. As a high force, direct drive solution, Moog's linear motors extend maintenance intervals and reduce the cost of ownership of any linear motion system. These devices are easy to install and have a rugged and durable design with built-in thermal and fault detection.
