The Model 8515 is a medium-energy, high voltage, capacitor discharge type magnetizer capable of saturating Ceramic and Rare Earth magnetic materials. The Model 8515 is easily adapted to a wide range of production and laboratory magnetizing requirements. A modern solid-state electronic control circuit, coupled with a rugged, heavy-duty discharge SCR and fixture, make this magnetizer a highly reliable, low maintenance unit. The electronic voltage control circuit prevents the Model 8515 from being discharged before the preset energy level has been reached, avoiding incomplete magnet saturation. An easy to read front panel meter monitors the capacitor voltage. The energy storage level can be easily changed in the field. Integral electrical interlock and fail-safe circuitry provide a high degree of operator safety.

Applications

The Model 8515 Magnetizers, with proper fixtures, are capable of saturating a wide range of sizes and configurations of permanent magnet assemblies, including: PM motors, loudspeakers, linear actuators, magnetrons, TWT magnets, torque motors, relays, multi-pole timing motors, etc. The magnetizing fixture transforms the capacitor-stored energy (discharge as a current) into magnetizing energy (a pulsed magnetic field). Fixtures are designed to provide the field shape, direction, and intensity to accommodate a specific magnet. Fixtures that simulate certain magnetic circuits are available. Both air core and steel core fixtures are commonly used.
