Electromagnets and Power Supplies
BUYMAGNETS.com Electromagnets provide an efficient and economical solution for handling and holding parts. Electromagnets are available in a number of shapes and sizes. Bunting® Electromagnets require little maintenance and can be used in a variety of manual and automated applications. Electromagnets are a combination of electricity and magnetism. In an electromagnet, the magnetic field is produced by an electric current and disappears when the magnet is turned off. Through controlled use of electricity, the electromagnet can attract and hold heavy iron, scrap steel and other ferrous materials. The primary benefit of an electromagnet over a standard magnet is the strength can be controlled. Our line of Flat-Faced Round and Rectangular Electromagnets, Small Bi-Polar Electromagnets, Low Profile Electromagnets and Round Lifting Electromagnets will safely pick-up and move your material. Note – a power supply is needed to operate and release the item as required. Electromagnets must be able to release ferrous object as readily as they attract and hold them. Release is the function of the Power Supply – not the magnet. Power Supplies render a reverse current that ensures positive release of even those alloy steels that retain induced magnetism extremely well. All Bunting Power Supplies are designed to provide D.C. power for industrial electromagnets.
BPS1 Power Supplies feature a 3-position manual control switch for on-off-release, an indicator light, 6’ input cord with plug, 3’ output cord, and a splash-resistant enclosure.
BPS3 Power Supplies cycle and release rapidly and cleanly, making them excellent for high-speed automated processes. An SPST switch, limit switch, or PLC output may be used to operate the Power Supply. The release cycle is completely automatic, so operator judgement is not required even with manual switches. An adjustable timed pulse of reverse current to the magnet effectively releases the load. BPSE Power Supplies are ideal for robotics or “pick and place” applications.
