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
A new white paper by the Association for Advancing Automation says that increases in industrial robot shipments correlates positively with increases in US job growth based on Bureau of Labor statistics. The result could be new types of manufacturing and engineering jobs.
