The Advantages of a Direct Drive Approach
K-Series motors provide machine designers with the advantage of lower costs, increased reliability, and improved performance.

• Zero mechanical connections between motor and load
  • No inertia match required (no compliance / wind up)
  • Stiffer / more responsive system (easier to tune)
  • No maintenance / repair of mechanical linkages (couplings, etc.)
  • Smaller envelope for tight spaces
  • 6 frame sizes with multiple stack lengths
  • Shaft speeds to 8000 rpm
  • Rated torques up to 26 Nm (227 in-lbs)
  • Multiple winding selections for optimized performance
  • Lower cost solution
