Danfoss is a world leader within production of low speed hydraulic motors with high torque. We can offer
more than 3000 different hydraulic motors, categorised in types, variants and sizes (incl. different shaft
versions).
The motors vary in size (rated displacement) from 25 cm3 [1.5 in3] to 800 cm3 [48.9 in3] per revolution.
Speeds range up to approx. 1700 min-1 (rpm) for the smallest type and up to approx
600 min-1 (rpm) for the largest type.
Maximum operating torques vary from 13 Nm [115 lbf·in] to 2700 Nm [24.000 lbf·in] (peak) and maximum
outputs are from 12 kW [16.1 hp] to 70 kW [95 hp].
Characteristic 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
•
Long life under extreme operating conditions
•
Robust and compact design
•
High radial and axial bearing capacity
•
For applications in both open and closed loop hydraulic systems
•
Suitable for a wide variety of hydraulics fluids
•
The programme is characterised by technical features appealing to a large number of applications and a
part of the programme is characterised by motors that can be adapted to a given application. Adaptions
comprise the following variants among others:
Motors with corrosion resistant parts
•
Wheel motors with recessed mounting flange
•
Short motors without bearings
•
Ultra short motors
•
Motors with integrated positive holding brake
•
Motors with integrated negative holding brake
•
Motors with integrated flushing valve
•
Motors with speed sensor
•
Motors with tacho connection
•
All motors are available with black finish paint
•
Survey of Literature with Technical Data on Danfoss Hydraulic Motors
Detailed data on all Danfoss motors can be found in our motor catalogue, which is divided into 5
individual subcatalogues:
General information on Danfoss hydraulic motors: function, use, selection of hydraulic motor,
•
hydraulic systems, etc.
Technical data on large motors: OMT and OMV
Danfoss has developed a speed sensor specially designed for LSHT motors.
The electric output signal is a standard voltage signal that can be used for regulating the speed motor.
Principle
The speed is measured by a sensor in accordance with the Hall principle. Signal processing and
amplification are performed in the sensor housing. A connection is provided in the housing for a Binder
Series 713 plug or a plug with 5 metres of cable (available from Danfoss). The sensor can also be supplied
with 2 metres molded in cable.
