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 ...

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 ...

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 ...

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 ...

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

For maximum efficiency, the boundary conditions of the complete electro-mechanical system should be mapped During the optimization of a stepper-motor-based motion control system design an engineer ...

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 ...

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

For the last 40 years, stepper motors have been used in applications requiring tight position control at an affordable price. The advantageous economics stem from simplicity. Steppers deliver accurate ...

[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 ...
