  • High energy neodymium magnet rotors provide high acceleration/deceleration in minimum package size
  • Eight pole motor design for high torque and low cogging
  • Temperature sensors built into windings allow intelligent shut down in overload conditions
  • Unique stator design provides optimal thermal transfer to handle high hit-rate, demanding applications
  • High radial load rating allows use of direct mount pinions and belt pulleys for cost-effective application
  • Standard cable sets simplify machine design, build and commissioning
  • Flexible feedback options include incremental encoder standard, with high resolution and multi-turn absolute encoder available
  • IEC form factor simplifies machine design by allowing use of standard gearboxes and mounting plates
  • IP65 packaging ensures reliable operation in harsh environments
  • Maintenance-free design
  • UL, cUL and CE Mark allow worldwide application
