Variable-reluctance sensors are preferred for industrial and automotive environments, because they sustain mechanical vibration and operation to 300°C. In most applications, they sense a steel target ...

Bipolar Hall-effect sensors are used in BLDC motors to detect the position of the rotating magnet. In this example, an eight-pole motor with a three-phase winding uses three bipolar latching ...

Automobiles today contain a growing number of position and speed sensors that look at rotation. From transmission input and output shafts, crankshafts, and even individual tire speeds, these sensors ...

TDK Corp. has introduced the Micronas HAL 302x family of 2D Hall-effect position sensors for stray-field motor position sensing, delivering high angular accuracy performance in challenging mechanical ...

This file type includes high-resolution graphics and schematics when applicable. In the seemingly endless quest for higher motor performance and improved system cost efficiencies, motor manufacturers ...

They can be more efficient than induction motors and work at variable speeds. They are also inherently simple. For a time, they powered Maytag Neptune washing machines. Switched-reluctance (SR) motors ...
