This Design Idea further develops a previous one integrating a stepper-motor driver in a CPLD (Reference 1). However, this idea integrates not only the driver, but also a simple one-axis stepper-motor ...

Stepper motors are brushless and very reliable, since there are no contact brushes inside the motor. Therefore, the life of the motor is simply dependent on the life of the mechanical bearing. A ...

The PCM4806E is the latest addition to the IDEA Drive line. The RoHS-compliant drive lets an encoder input to the controller for closed-loop position correction capability. The drive is optimized to ...

When you think about highly-precise actuators, stepper motors probably aren’t the first device that comes to mind. However, as [Diffraction Limited]’s sub-micron capable micro-manipulator shows, they ...

Using pulse outputs from a PLC is a cost-effective way to get simple motion. Most, if not all, PLC manufacturers provide a way to control servos and steppers using a pulse train signal. So when a ...

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 ...

Motor controllers receive supply voltages and provide signals to motor drives that are interfaced to motors. They are used to start, stop, and run motors in a programmed manner. Motor controllers can ...

The primary feature of stepper motors is listed right within their name: their ability to ‘step’ forwards and backwards, something which they (ideally) can do perfectly in sync with the input provided ...

When deciding whether to build or buy, OEMs need to consider a myriad of factors including required design efforts, up-front costs and ongoing support. Stepper motors are popular due to their low cost ...

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 ...
