Pneumatic motors

PTM Pneumatic Motors, powerful and robust pneumatic motors for high-torque applications

The pneumatic motors developed by PTM mechatronics are reliable, high-performance solutions for industrial applications that demand high torque, precise control, and maximum safety, including operations in ATEX-rated environments. Thanks to their radial piston technology, PTM motors offer outstanding energy efficiency, with optimized air consumption and performance significantly superior to traditional pneumatic motors.

Compact, quiet, and completely lubrication-free, PTM motors are especially well-suited for clean or sensitive environments such as the food industry, pharmaceuticals, fine chemicals, as well as for dosing, mixing, driving, or positioning processes. Their mechanical robustness, minimal maintenance needs, and wide variety of configurations, including hollow shafts, flange-mounted designs, stainless-steel versions, and more allow for flexible integration into all types of machinery and automated systems.

All PTM pneumatic motors operate from 0 rpm to 300 rpm, deliver torque from 4 Nm to 32 Nm, and are available in four sizes. They run at operating pressures from 2 bar to 6 bar, with or without a connection block (including integrated speed limiter and fittings). They are oil- and silicone-free, feature anodized aluminum housings (except for the stainless-steel version), offer IP67 protection, and maintain noise levels below 75 dB.

Five main categories designed for extreme environmental conditions:

BASIC: Easy to install in standard production environments.
ATEX Motors: Certified for hazardous and explosive atmospheres (ATEX Zone 1+2+21+22).
IP68 Waterproof Motors: IP67 rated with enhanced protection for use in wet conditions, including seawater resistance.
FDA Stainless Steel Motors: Designed for the stringent hygiene demands of the food and beverage sector and for exposure to aggressive substances (ISO Class 1 cleanroom compliant).
Ferrite-Free Motors: Available in a single size (4 Nm). Constructed from non-ferrous, non-magnetic materials for use in magnetically sensitive environments, such as MRI applications.
