There are a lot of fun projects you can do with stepper motors salvaged from old printers or disk drives. However, it isn’t always clear how to connect to some strange motor with no markings or ...

Engineers rely on motion-control devices to improve efficiencies and production rates on automated factory floors, or at least maintain them. One family of such devices, stepper motors, is widely used ...

When applying step motors, designers need to consider several factors, including output torque, rotor inertia, step angle, and speed. Having already discussed the effects of torque and inertia (August ...

Sometimes less is more. Here, a quarter-step switching logic sequence for stepper motors offers several significant advantages over full-and halfstep modes—higher resolution, smoother drive, minimal ...

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 ...

Motors can be wired delta or wye. Which arrangement do you choose, and how do you do it? For purposes of making the connection, it doesn’t matter to the installer if the motor is delta-wound or ...

The Model WC300 Automatic Wire & Tubing Cutter is a compact, stepper motor driven cutter that can process wire and small cables from 10 to 30 AWG and sleeving or tubing up to 5/16 in. into any lengths ...
