Pittman Introduces CAD Models for DC Brush Motors

Pittman Motors, a division of AMETEK Precision Motion Control, has introduced configurable DC motor 3-D model downloads.The 3-D model system is an online system through the Pittman website that allows an engineer to fully configure a DC brush motor with a wide variety of optional components such as planetary and spur gearboxes, brakes, and encoders. The online 3-D model system makes it very easy for an engineer to evaluate different part configurations in a virtual environment. The customer can configure a part by choosing such parameters as motor voltage, torque rating, gearbox ratio, and encoder resolution.

After configuring a part as many times as necessary, the file can then be downloaded in the most commonly used CAD software file formats, including SolidWorks, CATIA, and Pro/E. The file also can be downloaded in a vendor-neutral format such as an .IGS or .STP file.  The system allows the creation of a fully dimensioned outline drawing generated directly from the configured CAD model.  

After a virtual configuration is created using the online 3-D model system, a product engineer can work closely with a Pittman applications engineers to create a more customized application-specific solution.  Options include optimized motor windings, unique shaft configurations, various bearing systems, output devices such as pinions and pulleys, special lead wire assemblies, EMI/RFI suppression networks, and various other features.  To discuss an application in more detail, engineers can be reached at 267-933-2105.

Pittman DC brush motors are available in a variety of sizes, torque and power ratings.  Diameters range from 0.866-in (22 mm) to 3.25-in (83 mm) and torque output from 0.8 oz-in (0.005 Nm) to 225 oz-in (1.588 Nm) without a gearbox. Both planetary and spur gearboxes are available for any DC motor diameter, greatly increasing the available torque output.Gear ratios up to 4732.5:1 are possible. A wide variety of encoder types are also available designed to meet just about any application requirement. Product applications for Pittman motors are diverse and span a wide variety of high-tech industries, including medical instruments, laboratory automation, semiconductor manufacturing equipment, and laser and optics equipment, or just about any other application where precision motion is needed.
