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 ...

Stepper motors divide a full rotation into hundreds of discrete steps, which makes them ideal to precisely control movements, be it in cars, robots, 3D printers or CNC machines. Most stepper motors ...

The first installment of this two-part series focused on debugging brushed-DC motor systems. Now the second installment will share some tips for stepper motor systems and provide general bench testing ...

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, ...

Higher-than-normal operating voltages give steppers better torque at high speeds — but watch that current! • The inductance in a stepper-motor phase winding limits how fast current rises when power is ...

Stepper motors produce accurate, computer-controlled motion for applications such as robotic arms and paper-feed mechanisms for printers. They require current pulses delivered through a special ...

An improved stepper motor driver IC, which offers 50% lower on-resistance, lets engineers increase the power rating of their designs while reducing waste heat. The TB67S559FTG 50-V/3.0-A stepper motor ...

Even veteran engineers often suffer from a lot of misconceptions about stepper motors and how to drive them. This article will focus on clearing up just a few of these misunderstandings so that ...

Allegro MicroSystems has unveiled a 40 V motor driver IC capable of driving one stepper motor and one DC motor. The bipolar stepper driver outputs are rated up to 1.6 A and the high current DC driver ...

Toshiba Electronics Europe has introduced the TB67S559FTG 50V/3.0A stepper motor driver IC that supports constant current control with built-in current detection. 50V/3.0A constant current stepper ...

Toshiba has launched "TB67S10xA" series of stepping motor driver ICs that realize high voltage, high current and low heat-generation. Sample shipment will start on July 17. High speed, high power ...
