Nanotec will reportedly be the first manufacturer in the world to launch a sensorless control for stepper motors in which the speed of the rotor is determined by means of a "virtual encoder" within ...

AMI Semiconductor has introduced two single-chip stepper motor driver and controller ICs, each offering sensorless stall detection. Target applications include headlamp leveling and swiveling and ...

In addition, an integrated current reduction function increases performance and reduces energy consumption. With the current reduction function comes integrated sensorless, load-dependent current ...

The primary feature of stepper motors is listed right within their name: their ability to ‘step’ forwards and backwards, something which they (ideally) can do perfectly in sync with the input provided ...

[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 ...

AMI Semiconductor has expanded its family of single-chip stepper motor driver and controller ICs with two new devices that incorporate sensorless stall detection. The new ICs will improve reliability ...
