Nanotec will 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 the ...

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 announced two new single-chip stepper motor driver ICs that will significantly reduce component count and bill of materials (BOM) cost in dynamic motion applications. Devices ...

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 ...

Engineers rely on motion-control devices to improve efficiencies and production rates on automated factory floors, or at least maintain them. One family of such devices, stepper motors, is widely used ...

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 ...

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 ...

STMicroelectronics has released the STM32 ZeST (Zero Speed Full Torque) software algorithm, designed to run on STM32 microcontrollers, that lets sensorless motor drives produce full torque at zero ...

Brushless motors are ubiquitous in RC applications and robotics, but are usually driven with low-cost motor controllers that have to be controlled with RC-style PWM signals and don’t allow for much ...
