Elk Grove Village, Ill. – With the recent introduction of its 1FN6 Linear Motors, Siemens now offers three models of Linear Motors for seamless integration with all Sinumerik or Simotion control systems using Sinamics drives. The three new motors are the 1FN3 Peak Load Motor, 1FN3 Continuous Load Motor, and the1FN6 Magnet Free Secondary.
The 1FN3 Peak Load Motors feature high acceleration/deceleration and velocity rates and can be used for horizontal or compensated vertical axes. They feature nominal force of 8,100 N, maximum force of 20,700 N, and maximum velocity of 253 m/min with liquid cooling.
The 1FN3 Continuous Load Motors feature long power-on duration for horizontal, inclined or compensated vertical axes. Nominal force is 10,375 N, maximum force is 17,610 N with maximum velocity of 129 m/min with liquid cooling. Both the 1FN3 Peak and Continuous load motors can be run with air convection cooling, but the ratings must be reduced by 50%.
Lastly, 1FN6 Magnet Free Secondary motors are ideal for long traverse lengths at high acceleration and velocity rates and can be used for horizontal, inclined or compensated vertical axes. The nominal force is 2,110 N with maximum force of 8,080 N and a maximum velocity 532 m/min with air convection cooling.
One linear motor stationary track (either with magnets or magnet-free) can support multiple primary sections moving either the same slide in a master-slave configuration or moving separate slides independently at different rates and in different directions. This allows designers to consolidate drive systems on multiple slide machines for cost efficiency and better productivity. Also, linear scales for position and velocity feedback are available from a variety of third party suppliers to suit the application.
To help in the design and application process, Siemens has developed a number of tools to help take a slide design application and configure the right size motor to it. Once this process is complete, it is a simple matter to integrate the motor(s) into a complete Siemens system that includes controls, motors, operator stations and even complete panels and cabinets.
