Take an initial broad based approach in DC power systems selection

While in the R&D phase of product development, keep your options open on what type and size DC motor you'll select for production. For instance, when designing systems with electric motors for automobiles, many specs will change throughout product development and even into the production phase of the project.

I recommend: Thomas Publishing Company gives you the most extensive products available to engineering, manufacturing and research and development departments. You can even find a local supplier by narrowing your search to your state. GlobalSpec is an engineering catalog search tool that allows you to select the best possible matches by limiting the listing specifications. You'll need to register to use the site, but the process is relatively quick.

Narrow your selection to a few DC motor producers

There are a number of different manufacturers that specialize in a specific type of DC motors. Find manufacturers and distributors that specialize in your size and power of motor. Share with their sales associate the application and discuss proper options. You may also want to check the spec sheet to be sure it produces adequate horsepower and current requirements.

I recommend: If you are looking for small appliance DC motors, a great resource is Motor Technology. They can custom make a DC motor for your project with the motor it needs. If you need a larger powered DC motor for manufacturing or other applications, try Bison Gear and Engineering Corp. They can custom build a DC motor to your specs as well.

Get several quotes from your DC motor suppliers

Once your motor specs are well defined in the project, you'll want to approach several manufacturers and/or suppliers for price quotes meeting your specs. Contact the sales staff and request a price plan for initial purchase price and high volume discount pricing.

I recommend: Anaheim Automation has a convenient online quote request form. Another DC motor maker, maxon precision motors, takes a more personal approach. They provide contact information for the regional service providers. You may want to contact an associate and discuss your needs, then send your spec sheet.
