Model 7500/900 Series Magnetizer

Model 7500/900-I Series Magnetizer

 

Features

  • Energy Levels from 6,000 to 24,000 Joules (Watt-Second)
  • Fast Recycle Time
  • Voltage from 50 to 850 Volts
  • Safety Interlocks
  • Saturation of Alnico, Ceramic, Rare Earth Magnetic Materials
Description
The Model 7500/900 Series Magnetizer is a high energy, capacitive discharge magnetizer capable of saturating Alnico, Ceramic and Rare Earth magnetic materials. A solid state electronic control circuit coupled with rugged, heavy duty discharge SCR's or ignitrons and fixtures, make this magnetizer a highly reliable, low maintenance unit. The electronic voltage control circuit prevents discharging the Model 7500/900 before the preset energy level has been reached, avoiding incomplete magnet saturation. An easy to read front panel meter monitors the capacitor voltage at all times.
Applications
The Model 7500/900 Series Magnetizer, when used with proper fixturing, is capable of saturating virtually all sizes and configurations of permanent magnet assemblies, including PM motors, loudspeakers, linear actuators, magnetrons, TWT magnets, torque motors, and relays. Ideally suited for magnetization of Rare Earth magnets and assemblies, and large volume Alnico magnets and assemblies requiring long high energy pulses for saturation. Magnetizing fields in excess of 100,000 oersteds can be produced in specially designed fixtures.
Our engineers welcome the opportunity to discuss adapting the Model 7500/900 to your specific magnetics application.
