Torque [Nm] Speed [r/min] Stall torque Min starting torque Torque Power Introducing the air motor The air motor is one of the toughest and most versatile power units available to today´s design engineer. It is easy to control over a wide speed range, and it produces maximum torque where it is often most needed – at start up. The performance of an air motor is dependant on the inlet pressure. At a constant inlet pressure, ungoverned air motors exhibit the characteristic linear output torque/speed relationship. Figure 1. However, by simply regulating the air supply, using the techniques of...

Understanding the performance curves The output of an air motor is most clearly seen from its performance curves Figure 8. For each motor/gear unit the power, torque and air consumption are shown as a function of speed. The diagrams shown apply to an inlet pressure of 6.3 bar, to calculate performance at other pressures refer to page 70 in this catalogue. Motor selection Guidelines on motor selection are given on page 70 in this catalogue – Choosing Your Motor. Methods of modifying motor output Throttling A throttle is usually fitted into the motor´s inlet hose, although it can also be...

Lubrication free air motors Atlas Copco’s lubrication free air motors are equipped with low-friction vanes, sealed bearings and vented cylinder plates. Since they release no lubricants into the air, they offer a viable drive solution for sensitive processes and hygienic environments where oil contamination would be at best a problem and, at worst, a catastrophe. LZB 33 high torque – low speed air motors Accomplishing high torques generally calls for very large motors with correspondingly high air consumption. The LZB 33 high torque/low speed air motors are based on the combination of LZB...

Reversible Motor The compressed air supply should be connected to the inlet that gives the desired direction of rotation, Figure 17. The inlet not in use functions as an additional outlet: it must not be plugged. Hose dimensions Information on hose dimensions recommended for use with type LZB air motors is detailed in Table 2. These dimensions are valid for hose lengths up to 3 m. If lengths above that are used, choose a one size larger hose. Hose size up to 3m length. Figure 17 Table 2 Mounting Type LZB vane motors may be mounted in any position. To facilitate this, flange and foot...

Vane motors LZB 22 LR, LZB 22R LR Low speed reversible Maximum permitted torque 9 Nm (6.6 lbf.ft). For EX certification according to the ATEX directive (Ex II 2G T5 IIC D85°C) use Ordering No. 9834 1108 00 (book as one delivery together with motor). EX certification for LZB 22 LR valid for fixtured mounted use only. Within their working range these motors have a very steep torque curve. Speed and air consumption is relatively constant regardless of the load. Data at air pressure 6.3 bar (91psi) Dimensions LZB 22 RL (mm) Optional Mountings Foot for LZB 22 LR Ordering No. 4430 0160 80...
