Harmonic Drive Servo Mount Gearheads
High Performance Gearheads for Servo & Stepper Motors
• Harmonic Drive offers two servo gear reduction technologies
• Harmonic Planetary® Gearheads
• Harmonic Drive® Gearheads
• Harmonic Planetary® gearhead designs use either a 3 or 4
planet carrier construction covering ratios from 3:1 up to
50:1 (single & double stage designs)
• Harmonic Drive® gearhead designs use an elasto-
mechanical wave reduction technology spanning ratios of
50:1 through 160:1
