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 ...

Nanotec has introduced a driver for stepper and brush-less dc (BLDC) motors with sensor-less closed-loop and field-oriented control (FOC). Intended for steppers from NEMA 14 to NEMA 34 and BLDC motors ...

Sensorless control of stepper motors, in which the speed of the rotor is determined through a virtual encoder within the controller, is possible, claims German firm Nanotec. “This enables the stepper ...

"The need for real-time motor control is more critical than ever, thanks to broad-reaching trends like power efficiency and automation, as well as increasing demand for quieter motors," said Noman ...

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 ...

Traditional sensorless motor control development is complicated and unattainable for most developers due to cost, time and the constraints of dealing with real world applications. This new technology ...

Closed-loop stepper-motor control with step-loss compensation is a common performance-boosting algorithm for stepper systems. In one prevalent form of step-loss compensation, an angle sensor or ...

Demand for low-cost, robust motor drives has spurred increased use of sensorless vector control of induction and BLDC motors — in everything from consumer products to industrial applications, in ...

[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 ...
