The AC electromagnet can produce an alternating magnetic field with adjustable amplitude in the frequency range of 50~499Hz. AC electromagnets are best used for the purpose of testing materials in an alternating magnetic field
The AC electromagnet is made of special silicon steel sheets that form an E-shaped yoke, which is a fixed air gap. The magnetic poles are packaged at both ends of the pole and the magnetic field has a vertical direction.
The pole face of the electromagnet is a square 45*45mm², the air gap is 10mm, and the maximum magnetic field H is more than 10000Gs. The 45Hz~499Hz frequency is continuously adjustable; the magnetic field is continuously adjustable, and the maximum magnetic field can reach 1.0T (amplitude value, the same below). The 100Hz magnetic field can reach a maximum value of 0.5T; at 200 Hz it is about 0.2T. The magnetic field at 499Hz can reach 200~300Gs.
Uniform zone: In the magnetic field center 10*10*10mm³, the magnetic field uniformity ΔH/H is approximately 0.03.
Working time: Using low current density power-on operation, the wire package has vents, cooling with air cooling to ensure that the magnetic field is rated maximum, the long-term working temperature rise is less than 20 °C.
AC power, 12kW. The single-phase output has a maximum voltage of 300V, a rated output current of 40A, and a load regulation rate of 0.5%. Voltage and frequency adjustable; frequency adjustable range 50 ~ 499Hz; display interface: voltage, current, frequency and power indicator.
The net weight of the electromagnet is about 150kg.
