DANFOSS ORBITAL MOTOR

Orbital Motors Introduction

Danfoss is a world leader within production of low speed orbital motors with high torque. We can offer more than 1500 different orbital motors, categorized in types, variants and sizes (including different shaft versions).
The motors size vary (rated displacement) from 130 to 800 cm3 [7.9 to 48.9 in3] per revolution Motor sizes:

  • OMT and OMV
  • TMK
  • TMT
  • TMTHW
  • TMVW

Speeds range up to approximate 600 min-1 (rpm).
Maximum operating torques up to 3400 Nm [30090 lbin] (peak) and maximum outputs up to 70 kW [95 hp].

Orbital Motors Features
