B&R's 8JS three-phase synchronous motors have been specially developed for use in high-performance applications. They are now being used to produce consumer goods and products in the plastic, packaging, metal, food and beverage industries and then palletize them with material handling systems. Complete solutions from one source: this requires the right components as well as the right configuration for the application environment. The large selection of available 8JS three-phase synchronous motors makes it possible to easily meet conditions such as reducing the variety of parts, guaranteeing ease of service and maintaining minimum requirements on space.

 

An optimally configured drive rounds off a successful design. To meet this goal, specialists are available at B&R subsidiaries all over the world who are eager to share their know-how in the area of mechatronics. B&R automation components: the economical combination of mechanics, electronics, technology and innovation.

Three-phase synchronous motors from the 8JS series are permanently excited, electronically commutated synchronous motors for applications that require excellent dynamic characteristics and positioning precision as well as compact size and reduced weight.

  • NdFeB permanent magnets
  • Sinusoidal commutation with EnDat encoder or resolver as feedback unit
  • Three-phase winding with star connection
  • Compact sizes result in low weight
  • Minimum moment of inertia because of favorable rotor construction results in very good dynamic properties
  • High overload capability/peak torque
  • Optimized torque ripple
  • High dynamic torque at high speeds
  • Long life-span, all motor parts except for bearings are free of wear
  • Power dissipation generated in the stator diverted directly to the flange via the housing
  • Preloaded, grooved ball bearings which are sealed on both sides and greased
  • Complete motor system with stall torque ranging from 0.48 Nm to 53 Nm
  • Connection using two SpeedTEC circular plugs
  • Control via ACOPOS servo drives or ACOPOSmulti drive systems
