Electromagnetic Transmissions Solenoids Holding Magnets Solenoids for simple operation Single-acting solenoids are for common applications. The magnetic field delivered by the coil upon power-up attracts the core. Then, the nucleus becomes free again in the absence of current. They are thus available in different designs, folded sheet, square profiled, machined in the mass. Solenoids for [...]

Electromagnet or solenoid are general terms for all types of electromagnetic actuators. Basically, electromagnets or solenoids are devices that generate a magnetic field by means of an energized coil, guiding it through suitable iron parts with air gap. Here, magnetic poles are created inbetween which a magnetic force of attraction, the magnetic force, prevails. If [...]
What is microstepping? Microstepping is a method of controlling stepper motors, typically used to achieve higher resolution or smoother motion at low speeds. Stepper motors move in discrete steps, or fractions of a revolution. For example, a stepper motor with a 1.8 degree step angle will make 200 steps for every full revolution of the [...]
Differences Between Various Stepper Motors, Stepper motors: Differences between permanent magnet, variable reluctance, and hybrid types Stepper motors are commonly used in linear motion applications for their precise positioning capabilities and good holding torque. And while the basic operating principle is the same for all stepper motors, there are differences in operation and performance between [...]
How Electromagnets Work What do a wrecking yard, a rock concert and your front door have in common? They each use electromagnets, devices that create a magnetic field through the application of electricity. Wrecking yards employ extremely powerful electromagnets to move heavy pieces of scrap metal or even entire cars from one place to another. [...]
Importance of Magnet Drawings for Magnet Manufacturer Magnet Product drawings, i.e. product processing drawings, are also needed for magnet products, especially for some complex magnets, such as special-shaped magnets and motor magnets.
