Sensorless control of stepper motors, in which the speed of the rotor is determined through a virtual encoder within the controller, is possible, claims German firm Nanotec. “This enables the stepper ...

The International Electrotechnical Commission (IEC) defines a servo device as “an adjustable-speed AC power drive system that includes an AC motor integrated by feedback, a converter, and control, ...

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 ...

[Frank Herrmann] had an interesting idea to turn a geared DC motor into a servo motor assembly, but with a stepper motor-like interface. By stacking some small PCBs behind the motor body, it was ...

As a Machine Design article notes, the key to effectively specifying the right step motor is to find the balance between efficient operations and performance limitations. “[The term “Maximize torque ...

National Instruments (Nasdaq:NATI) today announced the latest version of the NI SoftMotion Development Module for LabVIEW, the revolutionary software that empowers machine builders and original ...

A new open source servo stepper designed for makers and developers has been launched via Kickstarter this week offering industrial reliability in an affordable open source design. The AnanasStepper ...

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 ...

The amount of noise in a motor depends on the type of motor, environmental conditions, and the specific application. Permanent magnet and hybrid stepper motors are generally quieter, as they have a ...
