Five performance classes – two sizesThe modular design of the pneumatic motors enables space –saving dimensions:We can supply two sizes with only a different diameter but a different torque. The smaller pneumatic motors have a rated load torque of 450 Ncm or 900 Ncm. The diameter of the housing is 99 mm.They are 60 mm smaller in diameter than the more powerful motors with a rated load torque of 1800 Ncm, 3600 Ncm and7200 Ncm and an outside diameter of 159 mm. Within their performance class, their size difference is only 60 mm in the diameter and in the length.Even if gearbox modules are added on to improve performance,the unit’s length increases only by a few centimetres.With the different options among other things also there areversions available as hollow shaft (external) and Va (1.4571) stainless.

Gearbox options Our range of planetary drives can provide additional torque, speed and air consumption to suit your application. Standard gearboxes:

− Gear with reduction 3:1 or 9:1− Gear with ratio 1:2

Special gearboxes on request. Dimensions for the gearbox are shown in the table on the opposite side.For all pneumatic motors are standard shafts available and if requested stronger shafts too (see dimensions d2, L4, L5, L6, L7 in the table)

Installation optionsMounting holes on the standard flange, as well as an optionalmounting profile, or alternatively a mounting flange offer possi-bilities of options for mounting the pneumatic motors in a minimumof space. In addition different adapter variants are available for the optimal air connection.

Control technology The control technology includes all the electronic control devices(excluding valve) required to ensure speed regulation and/or speedmonitoring of the pneumatic motors. The signals received from the Hall sensors, the frequency of which is monitored by the control electronics, regulate the selected motor speed, keeping it within the defined tolerance range on fluctuations of the load orcompressed air. A modern switching concept and the use ofhighly-integrated components ensure that the PMO-DRZ 030300speed controller is set apart by extreme safety, high ability, low construction volume and an affordable price.

PerformanceAir consumption

The technology

This radial-piston piston motor operates without con-rod or crankshaft. The star-shaped working pistons slide uponto a curve embedded into the inside of the casing. They are supplied with compressed air from the centre via arotating control ring and a fixed control shaft. This actively controls the pistons. The control ring is connected tothe cylinder disc, which is double mounted onto the control shaft.

When rotation starts, fresh air and waste air alternately supply and vent the pistons with compressed air. By rever-sing the fresh and waste air, right hand and left hand rotation can be effected, even under load.

This, in combination with the electronic speed control equalises fluctuations in the compressed air circuit and theload and keeps the selected speed constant in the range of tolerance.

The objective…

• High torques

• Low speeds

• Minimised air consumption

… and the following effects: • quiet and durable• low operating temperatures• controllable energy properties• increased performance with gearbox

• optimised energy utilisation• economical air consumption• compact design• universal installation

The concept:

in line with the economy principle, achieving maximumbenefit for the least possible input along the shortestpaths!

Input = air consumption Path = revolutions Benefit = performance

Speed - performance – air consumption, the ultimate magical triangle

In the standard version all these motors achieve maximum torque at the lowest speed (30 rpm). Also air consump-tion is smallest. The maximum speed is 300 rpm and should not be exceeded. The performance potential, as wellas the measured air consumption in the various speed ranges is easy to determine from the graphs of the indivi-dual motors.

The argument

Technical information:

Materials:• housing aluminium alloy • hard-coated or black anodised• steel parts• Delrin - NBR - special

Optional:• sea water resistance to IP 68• silicone free• rust-proof• EX-Certificate to RL94/9/EG• electronic speed control +/- 10% of the load change • with hollow shaft (external)• rust-proof Va jacket• different adapters for air connection

Temperature application range:• -10° C to +80° C

Operating medium:unoiled compressed air filtered to ≤ 5µis mandatory• For the increase of the lifespan, see under

www.ptmgmbh.com/Technical Information/Compressed air

Operating and/or installation range:• optional

Operating pressure:• max. 3 – 6 bar

Maintenance :• none required

Notes:the motor can generally be seamlessly matched to thevarious requirements of the application concerned bysetting the volume flow via either throttling or a pressurereduction. The compressibility of the air has a damping effect in allranges, which means that the PMO compressed airmotor can be started under load at any time. Fresh air throttling: achieves the best results with re-gard to lifespan, quiet running and air consumption. Waste air throttling: reduces lifespan and increases airconsumption. Warning: The vent hole M5 for a potential overpressurein the housing may never be sealed off!
