Magnetics Help Motors Achieve High Torque Levels

Introduced as a high performance alternative to more expensive servomotors, or other stepper designs, these new motors claim a torque per frame size of up to 380 oz.-in, 2.7 N-m. The T-Series NEMA 23 high torque, 1.8° step motors have high accuracy (0.036° typical) for very precise load positioning. The rugged, housingless square frame motors employ a magnetic circuit optimized to maximize performance in a small envelope, to reduce input power required, and to provide smooth micro-stepping operation. The steppers are available in standard and custom configurations for ease of system integration. Standard options include leaded or terminal box construction for enhanced operation and protection in demanding environments, as well as encoders and encoder mounting provisions to optimize control schemes. Shafts, gears, sprockets, connectors and windings can also be customized. PACIFIC SCIENTIFIC, Rockford, IL. (866) 316-8437.
