Sensorless control of brushless motors

Sensorless control of brushless motors
Many applications would benefit from a brushless motor without a sensor. There are various options for realizing this. A method developed by maxon is now setting new standards for precision and reliability. Driving a brushless motor requires control electronics for precise commutation. However, this is possible only if the control electronics “know” the exact position of the rotor at all times. Traditionally, this information was provided by sensors, e.g. Hall sensors, installed inside the motor. But it can be done differently. Read about the three basic principles that are easily adapted. Why sensorless control? Cost optimization for high control performance Rough ambient conditions

Faster Electronics, Faster Design with New SI/PI-Aware Memory Interfaces
Data-rate-to-gigabit speeds keep increasing, but your time remains finite when designing integrated circuits, circuit boards, computers, smartphones, gaming systems, and other products. This technical brief will expose problems with cumbersome, traditional SI analysis workflows in which power-aware SI analysis is done post-layout — where every change requires repeated model extractions to adequately understand SI effects from fluctuations in power and ground rails. It presents a solution in the form of an end-to-end in-design flow to help you minimize design iterations and help improve design margins.

3D Solver Automates the Time & Trouble of Rigid-Flex PCB Simulation, EM Analysis
Modern portable electronic devices use smaller, lighter weight, and lower-cost rigid-flex printed circuit boards. But these boards present challenges to electromagnetic (EM) analysis using many 3D numerical solvers (FEM and FDTD), mainly due to the bending boards in small spaces and the use of hatched ground and power planes. This white paper sheds light on the challenges and presents an automated simulation workflow using Cadence Clarity 3D Solver.
