The BLWRPG17 Series are cost effective Brushless DC Planetary Gearmotors. These motors are designed keeping the OEM in mind, using state of the art design parameters and low cost manufacturing. This allows us to offer these quality motors at exceptional prices. The BLWRPG17 Series include a planetary gearbox and a brushless DC motor in a compact fully integrated package. The brushless DC gearmotor is a perfect solution for applications requiring high torque or speeds under 500 RPM. These star wound motors come with integrated hall sensors for closed loop control for velocity applications. If the off-the-shelf gearmotors do no match your application, a motor can be wound or a gearbox can be selected to meet your specific requirements. We specialize in providing both off the shelf and custom solutions to handle any demanding application.
