Munich, Germany--Electric motors have undergone more change in the last ten years than the previous hundred. This is particularly true with ac induction motors. For example, users today can specify vector or inverter drives, as well as the convergence of both systems: sensorless vector control. Other emerging technologies include soft switching techniques and transient-resistant windings.
Computer models take over. Sensorless vector control blurs the distinction between inverter and vector drives. While open-loop inverters are relatively inexpensive, there is no method of feedback from the motor to allow
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.
