TU_Automotive put on its ADAS technology event in Detroit Oct. 16 and 17, featuring presentations from firms such as Toyota, Volvo, Ford, Lear Corp., Harman, Mitsubishi Electric, GM Ventures, Navigant Research, and start-up companies CalmCar, Seeva Technologies and AlphaCs Corp. Here are a few of the more intriguing displays we perused during the event. NEXT […]

FAQ: Piezoelectric motors, Part 2: drive circuits
Unlike better-known electromagnetic motors, the widely used piezoelectric-based motor/actuator provides precise, repeatable linear motion over short distances, and requires a voltage drive rather than a current drive. Part 1 of this FAQ looked at the moving piezoelectric element of the actuator. Part 2 looks at their drive requirements, which are very different than those of […]
FAQ: Piezoelectric motors, Part 1: actuators
Unlike better-known electromagnetic motors, the widely used piezoelectric-based motor/actuator provides precise, repeatable linear motion over short distances, and requires a voltage drive rather than a current drive. When we think “motor”, we usually think of rotating motion or perhaps a special “linear motor” which is a rotary motor which has been rolled out flat. To […]
