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 cm
3
[7.9 to 48.9 in
3
] 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 N•m [30090 lb•in] (peak) and maximum outputs up to 70 kW [95
hp].
Orbital Motors Features
•
Smooth running over the entire speed range
•
Constant operating torque over a wide speed range
•
High starting torque
•
High return pressure without the use of drain line (high pressure shaft seal)
•
High efficiency
•
High radial and axial bearing capacity
•
Long life under extreme operating conditions
•
Robust and compact design
•
For applications in both open and closed loop hydraulic systems
•
Suitable for a wide variety of hydraulics fluids
Technical Features
The program is characterized by technical features appealing to a large number of applications and by
motors that can be adapted to a given application.
Adaptions comprise the following variants:
•
Motors with:
‒
integrated negative holding brake
‒
speed sensor
‒
black finish paint
•
Short motors without bearings or Ultra short motors
•
Wheel motors with recessed mounting flange
Orbital Motors Application Areas
The orbital motors are used in the following application areas:
•
Construction equipment
•
Agricultural equipment
•
Material handling & Lifting equipment
