PK-M Series sizes 17 and 23 high-torque, hybrid step motors offer step-angle resolutions of 0.9-degrees full step and 0.45-degrees per half step. The motors also maintain holding torques of 22 to 44.4 oz-inches for the size 17 and 54.2 to 187.5 oz-inches for the size 23. The PK-M Series higher-step resolution results in an unloaded step accuracy of 0.05 degrees. Running torques of 20 oz-inches at 2,500 pps are developed for the smallest PK-M model, the PK243M-01BA, and up to 175 oz-inches at 1,100 pps for the largest PK-M family member, the PK268M-03BA.

Engineers at Fuel Cell Energy have found a way to take advantage of a side reaction, unique to their carbonate fuel cell that has nothing to do with energy production, as a potential, cost-effective solution to capturing carbon from fossil fuel power plants.
This is part one of an article discussing the University of Washington’s nationally ranked FSAE electric car (eCar) and combustible car (cCar). Stay tuned for part two, tomorrow, which will discuss the four unique PCBs used in both the eCar and cCars.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
