Our Story
OEM motion partners since 1998
One US point of contact - overseas manufacturing cost structure.
Source Engineering has established a team of manufacturing partners in Asia to provide our customers with high-quality, cost-effective motors, gearmotors, and motion control products. Our US engineering department is backed by a strong R&D team overseas, plus a quality control group that assures every delivery meets your specifications.
Founded in 1998 and headquartered at 3283-H De La Cruz Blvd. in Santa Clara, California, we have supported OEM design and sourcing teams for nearly three decades across robotics, medical, semiconductor, factory automation, and aerospace programs.

Customization
Customization is a core strength - not an add-on. We engineer motors, gearboxes, and motion assemblies to your specifications, from early machined samples through full production.
Custom programs that stay practical
