Accessories
A range of accessories is available to enhance the functionality and adaptability of pneumatic motors for specific applications.

Quality Assurance
The motors are designed to be insensitive to environmental conditions, ensuring reliability and performance in various settings.

Certified Use Categories

2: Suitable for use in 'Zone 1', where explosive gases or powders may occasionally be present.
G: Approved for use in explosive environments with gases, vapors, or mixtures.
IIB: Suitable for environments with gases like acetylene, hydrogen, and methane.
T4: Maximum allowable temperature class of 135°C on the motor's external surface, according to EN 13463-1.

Performance Characteristics
The performance of a pneumatic motor is defined by power, speed, torque, and consumption. The power delivered by the motor is expressed in Watts, torque in Nm, and speed in revolutions per minute. Consumption is measured in normal liters per minute (Nl/min).

Operational Dynamics
A motor starting without load operates at maximum speed without delivering power or torque. As load increases, speed decreases, and power output increases until it reaches a maximum. Further load increases result in higher torque but reduced power output, leading to motor stall at maximum torque.

Motor Performance and Torque Characteristics
The starting torque is approximately equal to the maximum torque, but may vary slightly depending on the rotor vane position. The speed at maximum output is about half of the no-load speed, and the torque at maximum power is about half the maximum torque.

Influence of Pressure
The performance of motors changes with varying pressure. Performance tables refer to the feed pressure at the motor's input, which can be significantly lower than the compressor's output due to load losses in pipes.

Energy and Ambient Temperature
The energy supplied to the motor from compressed air depends on the pressure difference between input and output. Standard OBER motors are designed to operate between 5 and 40 °C.

Air Supply and Lubrication
The performance and lifespan of pneumatic motors are significantly affected by air supply quality. Proper lubrication is crucial for optimal motor performance and to prevent premature wear.

Safety and Environmental Conditions
Pneumatic motors are resistant to environmental conditions and can operate underwater. They do not produce sparks or overheating, making them safe in flammable environments.

Motor Adjustment
Adjustment of an air motor can be done through supply pressure or airflow adjustments. Pressure adjustment is preferred for stall torque, while flow adjustment is used for speed control.

System Design
Users must choose the appropriate valve layout during the design phase to ensure machinery safety and functionality.

Applications for Pneumatic Motors
Significant applications include machine tools for drilling, grinding, milling, devices for mechanical part movement, and equipment for various industries.

OBER's Experience
OBER specializes in screwing and tapping motors, offering a range of standardized and customized models.

Qualità Certificata Il motore pneumatico è assolutamente insensibile alle condizioni dell’ambiente. Poiché ogni parte del motore è sempre a pressione maggiore di quella dell’ambiente, gli inevitabili giochi possono solo dar luogo a fughe d’aria e mai ad ingresso di alcuna sostanza. Il motore pneumatico può funzionare anche sott’acqua. Inoltre non produce scoppi, scintille, surriscaldamenti di alcun genere, oltre naturalmente a non avere il pericolo di corto circuito sia nel motore che nell’impianto di alimentazione. E’ pertanto assolutamente esente da pericolo di folgorazioni ed è anti-deflagrante....

Certified quality Qualidad Certificada The pneumatic motor is completely insensible to environmental conditions. Since each part of the motor is ever under a higher pressure than the one of the environment, this may give rise to air leaks and never let any substance enter. The pneumatic motor can work also under water. Moreover, it does not create bursts, sparks, and any kind of overheating, besides, obviously, not having the risk of short circuits in both, the motor and the power supply system. It is therefore free of the risk of electric shocks and it is explosion-proof. It can be used also...
