TRACK POSITION WITH MOTOR AND ENCODER, DESIGN FOR SMALL SPACES
02 May 2005 - Fieldbus Foundation

Lin Engineering, the technical leader in step motor design, is pleased to introduce their compact and lightweight step motor complete with a small E4 encoder from US Digital. The 1.8º 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” square and are available in three lengths; 1.24”, 1.75” and 1.99”. This 1.8º NEMA 11 motor provides high torque in a small package. Depending on the length, the 211 motor can produce maximum holding torques of 9.2 oz-in 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. The E4 encoder is capable of tracking 100 to 300 cycles per revolution; 400 to 1200 pulses per revolution. The E4 encoder will only add 0.9” of length to the 211 motor. Please note that encoder mating cables and connectors are not included and are available separately.

The 211 motor with E4 encoder is ideally suited for applications in the medical, robotics, communications and semiconductor industries.
