The new SilverPak 23DE, an integrated Nema 23, high torque, 1.8 degree 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 four 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.
The Beam Store from Suitable Technologies is managed by remote workers from places as diverse as New York and Sydney, Australia. Employees attend to store visitors through Beam Smart Presence Systems (SPSs) from the company. The systems combine mobility and video conferencing and allow people to communicate directly from a remote location via a screen as well as move around as if they are actually in the room.
An MIT research team has invented what they see as a solution to the need for biodegradable 3D-printable materials made from something besides petroleum-based sources: a water-based robotic additive extrusion method that makes objects from biodegradable hydrogel composites.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
