What Automotive Engineers are Missing When it Comes to Power Sources

October 16, 2009 7:41 am | by Chad Hall, COO of Ioxus | Comments

The demand for better and more efficient power sources in the automotive industry has been a driving force behind research in battery technology, capacitor technology, and electronic power supply design. In order to utilize energy as efficiently as possible, automotive engineers began by reducing the gross weight of an automobile

Comparing motor-control techniques

October 13, 2009 7:10 am | by Daniel Torres, Applications Engineer, Microchip | Comments

The majority of motor-control designers are consistently and continuously looking for methods to improve efficiency while reducing system cost. These are the two main factors that are driving the efforts to improve existing motor designs and motor-control techniques. A good example of this trend is the Permanent Magnet Synchronous Motor (PMSM).

Tech Advances Impact Motion Control

October 8, 2009 6:09 am | by Chuck Lewin, Founder & VP of Engineering, Performance Motion Devices | Comments

There are a number of technology trends that are profoundly changing how engineers are designing machines with motion control. Two among these stand out for their potential impact on cost, ease of assembly, and serviceability. These are the continual reduction of the size of the motion amplifier, and the advent of low cost, high-speed digital networks.

Driving 3-Phase Induction Motors

October 6, 2009 5:57 am | by Dr. Stephan Chmielus, Fairchild Semiconductor, Germany | Comments

Although an increasing interest and use of Permanent Magnet Synchronous Motors (PMSM) can be observed during the last decade, the standard 3-phase Induction Motor (IM) is still the most widely used electrical motor. The simplest way to start an IM is to connect the motor directly to the 3-phase main supply.
