Classic roller test stands generally have a design based on a two-mass oscillating system assembly – a some- what unfavorable concept. Using a SIMOTICS segment motor is an efficient way of improving the dynamic response of roller test stands. The direct drive technology allows the test stand design to be radically changed and innovated. 

• Easier to handle
  
• High availability: Continued operation even if individual stator segments fail
  
• Rigid design of the mechanical components: Direct drive technology instead of a two-mass oscillating system
  
• Better management of the control characteristics
  
• More compact overall design
  
• Space savings
  

Test stands are becoming increasingly faster and more dynamic. Efficient drive technology is a fundamental precondition in order to achieve the high demands on test stands based on linear motion. Completely new possibilities are created by integrating a SIMOTICS 1FN3 linear motor directly into the mechanical system of the test stand.

• High dynamic response
  
• Low wear on the mechanical components
  
• Simple mechanical design
  
• Applications with constant forces without damaging the mechanical components
  
• Replacement of hydraulic axes by electric drive technology
   

• Solution for battery simulation
  
• Solution for battery test
  
• All the components for the entire system from a single source
  
• Energy exchange in the DC link, resulting in low line supply power rating, thus smaller dimensioning of the shop floor network
  
• Retaining the 380 V - 480 V voltage level even for higher DC output voltages
