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 ...

Know the four most common microstepping myths. Myth 1: A high microstep count will result in evenly spaced steps at that count. Microstepping is good for smooth motion. However, having a 256 microstep ...

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 ...

• 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 ...

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) ...
