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 ...

As previously mentioned, the feedback sensors include position sensors to track the rotor’s location, current sensors to measure the motor phase currents, voltage sensors to monitor the DC bus voltage ...

In theory, you really don’t need much to work with electronics. A scope ought to do everything. However, for special purposes, it is handy to have meters, logic analyzers, and other special-purpose ...

The flux-oriented control (FOC) is a commonly used technique for three-phase electric motor control application. Here, the applied voltage pattern is defined using the space vector modulation (SVM) ...

Adjust the phase current, crank up the microstepping, and forget about it — that’s what most people want out of a stepper motor driver IC. Although they power most of our CNC machines and 3D printers, ...

Stepper motor systems are highly efficient when producing torque, but lack operational efficiency when not producing torque. Applied Motion Products offers insights on how to make a greener and more ...

Microstepping is a major advancement in step motor technology introduced many years ago that allows motors to make finer steps in movement. By manipulating the current vector, microstepping creates ...

In this installment of the back-to-basics electronic component series, in partnership with EDN, we cover current sensors. Don’t miss our discussion with Michael DiGangi, executive vice president of ...
