All of the motors measure 21mm from front to back, plus 8mm of shaft protrusion. In each case there is a standard and a higher holding-torque variant, for example: the 42mm 200mNm HS17HX7L4100 and its ...

Finding just the right off-the-shelf part to complete a project is a satisfying experience – buy it, bolt it on, get on with business. Things don’t always work out so easily, though, which often ...

There is increasing demand from engineers and specifiers working on complex motion control applications for cutting edge motors, especially those requiring high-torque, precise positioning and ...

AutomationDirect has expanded the line of SureStep motion control products. Stepping motors in standard NEMA sizes (17, 23, & 34) now include dual-shaft, bi-polar models with output torques ranging ...

The new PF25 stepper motor measures 25 mm in diameter and integrates a lead screw shaft. It is available with either Anisotropic ferrite or neodymium magnets. Motors using neodymium magnets have a ...

Hybrid stepper motors combine the operating principles of variable reluctance with permanent-magnet stepper motors. The rotor shaft holds one or more pairs of stacked laminations containing many teeth ...

It’s increasingly common for designers to pair stepper motors with motion-control SoCs. In fact, more design engineers than ever are setting up SoCs themselves for motion applications. These chips ...

Stepper motors resemble servo motors in that both types are characterized by an ability to rotate a partial turn and then stop for any interval with or without holding torque. In addition, both motor ...

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.

Over the last 2 years [Carl Bujega] has made a name for himself with his PCB motor designs. His latest adventure is to turn it into a stepper motor by adding position control with microstepping. The ...
