Bipolar stepper motors are used in many applications, from driving paper through a printer to moving an XY stage in industrial equipment. Typically, the motors are driven and controlled by inexpensive ...

This application note describes how to implement an exact linear speed controller for stepper motors. The stepper motor is an electromagnetic device that converts digital pulses into mechanical shaft ...

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 ...

Find a downloadable version of this story in pdf format at the end of the story. A new controller IC, the L6470 for stepper motors, integrates the power stage along with a digital control core on a ...

Encoder specialist POSITAL has expanded its line of kit-style encoders for feedback for servo and stepper motors with new models that utilize the same mounting form factor as incremental kit encoders ...

Encoders are fantastically useful devices for human-machine interfacing. The issue for the makers, teachers, students, and engineers trying to use them is that many have less-than-ideal output signals ...

Precisely tracking speed, acceleration, and position of a motor's rotor is an essential requirement for many motor control applications found in everyday equipment such as fax machines, elevators, and ...

Stepper motor linear actuators (SMLAs) combine a stepper motor, precision lead screw and nut in one compact envelope, providing a highly configurable, customizable and robust system for linear motion.

The International Electrotechnical Commission (IEC) defines a servo device as “an adjustable-speed AC power drive system that includes an AC motor integrated by feedback, a converter, and control, ...
