This compact and lightweight step motor comes complete with a small E4 encoder from US Digital. The 1.8 degree NEMA 11, bipolar stepper and miniature E4 encoder are designed for flexibility in applications with limited space. The 211 Series motors measure a mere 1.1 in. square and are available in three lengths: 1.24, 1.75, and 1.99 in. The motor provides high torque in a small package. Depending on the length, the 211 motor can produce maximum holding torques of 9.2 to 16.6 oz-in. The US Digital E4 miniature encoder is designed to provide digital quadrature encoder feedback of motor position as well as stall detection for applications with space constraints.
