LSM Technology Overview

 

Linear Synchronous Motor Technology - Advancing the Transport of Goods and People


MagneMotion’s core Linear Synchronous Motor (LSM) technology is scalable and adaptable to a wide range of applications, from small transport and positioning systems to large people movers. Unlike short stroke linear motors, LSMs generate propulsive force by running current through a stator creating an electro-magnetic field that interacts with a set of permanent magnets on a vehicle to create thrust. The permanent magnets serve as the motor secondary, equivalent to a rotor in conventional motors, enabling linear motion. The magnet array and vehicle is propelled by the moving electro-magnetic field, traveling along as electric current is applied to the stator beneath the vehicle. The vehicle’s movement is regulated by a sophisticated control system incorporating state-of-the-art position sensing technology.

LSM Overview

The two types of linear motors in most prevalent use are Linear Induction Motors (LIMs) and Linear Synchronous Motors (LSMs). While both motor types have appeal for certain applications, there are technical reasons why MagneMotion typically favors the use of the LSM. Some of the technical issues behind this preference are discussed in this section. More

Control Systems

Accurate and continuous control of vehicle movement and interaction is critical to the success of many transport systems. MagneMotion has developed a state-of-the-art control system with a scalable distributed architecture that can safely and efficiently manage many vehicles on a common network of track. More

Key Features and Advantages

Linear Synchronous Motors (LSMs) can be used anywhere that you need linear motion or actuation. Factory automation applications using chain- and belt-based conveyor systems, hydraulic actuators, and lead screw drives are a few examples where LSMs could produce the required action, serving as an alternative to these mechanically dependent devices. Advantages include the following:

  • Increase reliability fewer components subject to wear
  • Acceleration and braking not dependent on friction
  • Improve performance
  • Increased speed, acceleration, efficiency
  • Provide more precise position control
  • Negotiate steep grades without depending on friction
  • Any slope is possible, including vertical
  • Eliminate the need to have propulsion power and control on the vehicle
  • Vehicle can be passive
  • Ability to control multiple vehicles on complex trajectories
  • No need to transfer communication or control signals to a moving vehicle

 

Major improvements in LSM technology over the last decade have made electro-magnetic propulsion a more viable solution for manufacturing and transportation industries. LSMs now use better and less expensive power electronic components and faster and more versatile digital signal processors with motor control features. Our motor configurations have been optimized using more advanced research and design tools. LSMs are well suited to many types of industrial applications. Permanent magnets (specifically NdFeB magnets) have also become less expensive, and have a higher electro-magnetic energy product.
