--- title: Choose the right air motor in three easy steps - Step 2 Ascertain the torque of an air motor description: Once you know in which environment you will use the air motor, you need to figure out which torque is necessary for the task. Indeed, a motor speed depends on its torque and speed. By deciding those two facts, you will find the perfect air motor. image: https://blog.modec.fr/hubfs/Photo-t%C3%A9l%C3%A9phone.jpg --- [![modec-logo](https://blog.modec.fr/hs-fs/hubfs/modec-logo.png?width=2500&height=599&name=modec-logo.png "modec-logo")](https://modec.fr) - [Products](https://modec.fr/en/products/) - [Air motors](https://modec.fr/en/air-motors/) - [Pneumatic tools](https://modec.fr/en/air-motors/pneumatic-tools/) - [Flanges and shafts](https://modec.fr/en/air-motors/flanges-shafts/) - [Accessories](https://modec.fr/en/air-motors/accessories/) - [Options](https://modec.fr/en/air-motors/options/) - [Resources](https://modec.fr/en/resources/?product=motor) - [Applications](https://modec.fr/en/applications/) - [Portable valve actuators](https://modec.fr/en/portable-valve-actuators/) - [Resources](https://modec.fr/en/resources/?product=pva) - [Applications](https://modec.fr/en/applications/) - [Company](https://modec.fr/en/about-us/) - [About us](https://modec.fr/en/about-us/) - [Services & support](https://modec.fr/en/services-support/) - [Technologie and innovation](https://modec.fr/en/technology-innovation/) - [Resources](https://modec.fr/en/resources/) - [Air motors](https://modec.fr/en/resources/?product=motor) - [Technical documentation](https://modec.fr/en/resources/?type=technical-data-sheet-doc&product=motor) - [Manuals & Guides](https://modec.fr/en/resources/?type=user-manual&product=motor) - [Catalogues & brochures](https://modec.fr/en/resources/?type=catalog&product=motor) - [Maintenance](https://modec.fr/en/resources/?type=maintenance-video&product=motor) - [Portable valve actuators](https://modec.fr/en/resources/?product=pva) - [Technical documentation](https://modec.fr/en/resources/?type=technical-data-sheet-doc&product=pva) - [Manuals & Guides](https://modec.fr/en/resources/?type=user-manual&product=pva) - [Catalogues & brochures](https://modec.fr/en/resources/?type=catalog&product=pva) - [Maintenance](https://modec.fr/en/resources/?type=maintenance-video&product=pva) - Blogs - [Air motor Blog](https://blog.modec.fr/en) - [Portable valve actuators Blog](https://blog.modec.fr/portable-actuators) - [Contact](https://modec.fr/en/contact/) - [Contact us](https://modec.fr/en/contact/) - [Find a distributor](https://modec.fr/en/find-distributor/) - EN - [![francais modec](https://blog.modec.fr/hubfs/Files_Modec/images/fr.png)](https://blog.modec.fr?hsLang=fr) - [![](https://blog.modec.fr/hubfs/Files_Modec/images/es.png)](https://blog.modec.fr/es/motores?hsLang=fr) - [![](https://blog.modec.fr/hubfs/Files_Modec/images/de.png)](https://blog.modec.fr/mobileventilantriebe?hsLang=fr) MOTOR - CHOICE # Choose the right air motor in three easy steps - Step 2 Ascertain the torque of an air motor 2 avril 2019 MOTOR - CHOICE Once you know in which environment you will use the air motor, you need to figure out which torque is necessary for the task. Indeed, a motor speed depends on its torque and speed.

Is it the nominal torque, the starting torque or the stall torque I am interested in ? You need to know the starting torque if you are for example in the case of hoisting application  (a hoist or a winch which need to lift heavy loads from the start). You need to know the stall torque if you need your motor to stop when hitting a certain torque. For example, for any tightening applications where the motor stops automatically when the piece is screwed. As you understood, figuring out if you need a starting torque, a stall torque or even a nominal torque is crucial and not always easy. If you are not sure, you can [contact us](https://offers.modec.fr/en/contact-us?hsLang=fr) via our website or by phone and we will know how to advise you and if needed, land you motors for trials.
