Stepper motors offer unique advantages over direct current (DC) and brushless DC (BLDC) motors in many applications. A bipolar stepper provides accurate open-loop position as well as zero-speed torque without using a control loop or external sensors.Learn More
This paper will focus on the basics of the sensorless control algorithm, the advantages of different sensing techniques, and how the GUI can drive a full-featured sensorless sinusoidal BLDC motor with no software programming required.Learn More
There are four general categories of Hall-effect IC devices that provide a digital output: unipolar switches, bipolar switches, omnipolar switches, and latches. Latching Hall-effect sensor ICs, often referred to as "latches," are digital output Hall-effect switches that latch output states.Learn More
This paper introduces Hall-effect technology, then explores how it has been applied, in particular, differentiating between the primary types of Hall sensor ICs and the highly differentiated range of sensing behaviors they can support.Learn More
