• Hall-effect sensors used to control dc-electric motors can detect motor rotation direction, and rpm. • Improper inflation of aircraft tires drastically shortens tire life span, leading to premature ...
As previously mentioned, the feedback sensors include position sensors to track the rotor’s location, current sensors to measure the motor phase currents, voltage sensors to monitor the DC bus voltage ...
Sensor-less brushless dc motors do not have to be hard to drive, claims Allegro MicroSystems. “Start-up and run commutation can be customised for individual motors and loads by adjusting a few default ...
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 ...
Here is a motor speed sensor module, the major goal is to check the rate of an electric motor. The module can be used in association with a microcontroller for motor speed detection, pulse count, ...
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 ...
[Davide Gironi] shows us how to implement a sensorless brushless DC motor controller (sensorless BLDC) using an ATmega8 microcontroller. In order to control a BLDC motor you need to know its ...
In the first installment of this series, "Calculating a practical hotspot safety margin", we discussed how two-parameter thermal models assume that the entire motor, including windings, exhibits one ...
Featuring DC to 5-MHz bandwidth, Allegro MicroSystems' galvanically isolated, high-accuracy magnetic current-sensor IC with zero current reference (ACS37030), and overcurrent fault with internal pull ...
