Electromagnetic Transmissions Solenoids Holding Magnets

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 [...]

Energise to Hold Electromagnets

Energise to Hold Electromagnets / standard Electromagnets / Solenoid/Electromagnet Electrical current is required to turn the magnet ON. Power is removed to turn the magnet OFF. Pull force conversion (approximate): 1kg = 10N = 2.2lb. The outer shell of the electro magnet is a sturdy bright nickel plated cylinder, passivated with body mounting. Designed for [...]

TYPES OF HOLDING MAGNET Electromagnetic holding magnets: The ferromagnetic part is held in place on the holding magnet’s attraction surface when power is supplied to the coil. When the holding magnet is not powered, the electromagnetic force [...]

Solenoids

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 [...]
