Brush DC Motors

SEI permanent-magnet DC (PMDC) motors deliver high torque in a cost-effective package for variable-speed applications that do not require a gearhead. Motor diameters range from 31mm through 130mm with rated output power up to 1125W.

Sealed ball bearings and low-noise construction support long service life in consumer, industrial, and instrumentation products. Custom windings, cabling, connectors, shaft configurations, and encoders are available at OEM volumes.

FAQ

When should I use a standalone PMDC motor vs. a brush DC gearmotor?
Use a standalone PMDC motor when your application already includes a gearbox or requires direct-drive speed control. Choose an integrated brush DC gearmotor when you need matched motor and reduction in one unit.
Are custom windings available?
Yes. SEI can wind motors to match your target voltage, speed, and torque for OEM production programs.
