Source Engineering introduced planetary brush and brushless gearmotors for OEM applications. Gearmotors are best suited to applications requiring high torque and speed reduction and are available in ratios from 3:1 up to 3,729:1. According to the company's press release, the 22 mm and 56 mm diameter gearmotors can be supplied with 3–36 VDC motors, plastic, powder metal or cut metal gears and 2/3 channel quadrature optical encoders. The compact, center-shaft planetary gearheads are available in 22, 24, 25, 28, 32, 36, 45 and 56 mm frame sizes with either ball or sleeve output shaft bearings. In addition, the output shafts can be custom machined with cross-holes, splines, keyways and flat or end drilled and tapped. Designed for input speeds up to 6,000 rpm, continuous, rated torque is increased to 392 kg cm and max torque is typically three times rated torque. Planetary gearmotors can be customized to meet new and existing applications.
