H2W Compact High Force Ironcore Brushless Linear Motor

H2W engineers have developed a compact high force brushless linear motor (BLSM-1F) that can generate 300 lbs [1330 N] at a 10% duty cycle and 100 lbs [444 N] at a 100% duty cycle, and, when used with a matching magnet track (BLST-FSX). The mass of the coil assembly is 19 lbs [9 Kg] which gives a force to moving mass ratio of 15.8

The motor can be driven using either a trapezoidal or digital standard three phase brushless amplifier. The Brushless Linear Motor Coil measures  6.53” X 7.50” x 1.50” [170 mm x 190 mm x 38 mm]. This Brushless Linear Motor is designed for applications that require a wide speed range and a relatively high force. This motor is encapsulated using high temperature 350°F [176°C] thermally conductive potting compound which protects the components and seals it from dust and moisture. 

The 3-phase brushless linear motors, also known as an AC linear servo motors, are direct drive motors that are ideal for long stroke, closed loop servo, linear motion applications. They can be used at speeds up to 240 in/sec [6 m/sec]. They are capable of very precise position, velocity and acceleration control when coupled with a linear encoder for position feedback.  

The laminated 3 phase wound coil assembly is used in conjunction with a linear magnet track to produce a controlled linear force. A customer supplied bearing system is required to maintain the .060" [1.5 mm] air gap between the coil assembly and the magnet track.  There is a relatively large attractive force between the motor coil and the magnet assembly. The magnet track consists of rare earth neodymium magnets and the require overall length is equal to the coil assembly length plus the stroke length.  

Advantages:  

  • Uses a standard three-phase brushless amplifier
  • Multiple coils can operate on the same magnet track assembly
  • Unlimited stroke length
  • High force to moving mass ratio
  • The magnetic attractive force between the coil and magnet track assemblies creates preload for a bearing system

 Typical Brushless Linear Motor Applications: 

  • Conveying Systems
  • Baggage Handling 
  • Coordinate Measurement Machines
  • Laser and Water Jet Cutting
  • Pick-and-Place Machinery
