The new SilverPak 23DE, an integrated Nema 23, High Torque, 1.8° bipolar step motor, microstepping driver and encoder is designed to reduce overall design time and system cost for a wide array of step motor applications needing high torque. The SilverPak 23DE is 2.25 inches in width and is offered in three body lengths: 2.52, 2.96 and 3.89 inches. Depending on its stack size, the integrated motor/driver is capable of producing up to 294 oz-inch of holding torque. The SilverPak 23DE operates from 15 to 48V dc and the available phase current ranges from 0.3 to 3A peak. This integrated motor/driver combination features jumper configurable step resolutions ranging from 2X microstepping up to 256X microstepping and 4 selectable damping modes, optically isolated step, direction and disable/enable inputs, under-voltage and over-temperature protection, and Pole Damping Technology™ (PDT). Options available with the built-in encoder are Tracks up to 100,000 cycles/sec, 32 to 1250 CPR, Max 5000 pps, 2 channel quadrature TTL squarewave single ended outputs and optional index.

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.
To get to a trillion sensors in the IoT that we all look forward to, there are many challenges to commercialization that still remain, including interoperability, the lack of standards, and the issue of security, to name a few.
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.
