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 ...

Stepper motors are often used for positioning since they are cost-effective, easy to drive, and can be used in open-loop systems—meaning that they don’t require position feedback like servo motors.

When it’s time to specify a high-performance motor that offers both precise positioning and cost efficiency, stepper motors offer many advantages over DC motors thanks to their brushless technology.

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 ...

• The inductance in a stepper-motor phase winding limits how fast current rises when power is applied. • Series-resistor current limiting needs higher voltages for faster step rates, but higher ...

Physical testing is vital in a product’s journey from conception to its final destination, which involves client or patient interaction. Quality testing is integral in this process, occurring at ...

The torque wrench is probably the most often-used specialty tool. If you’re like us, you may still have your first torque wrench; we got our Craftsman ½-inch drive clicker-style as a Christmas present ...

Wireless rotary torque transducers are offered by Sensor Technology Ltd. They form the core of a test rig to design next-generation technologies for powertrains of hybrid and electric vehicles. AVID ...

BCT currently tests completed solar array drive assemblies (SADA). BCT would save time and money by testing stepper motors before integration. Our STEP (Stepper Testing Environment for Performance) ...
