Description
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.
Mode of Operation: Three modes of operation are available (switch selectable):
Auto Charge to Preset Level
Push to Discharge
Push to Charge
Auto Charge to
Preset Level
Push to Charge
Push to Discharge
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 (discharged 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.

* Lower charge voltages will produce faster recharge times, however, actual cycle times may
vary depending on fixture cooling requirements.
Typical Peak Magnetizing Forces:
Peak H will depend on the impedance of the charging fixture. Magnetizing forces in excess of
50,000 Oersteds can be achieved.
Magnetizing Pulse Characteristics: The rise time to the peak and overall pulse width will
depend on the fixture impedance and the capacitance of the magnetizer.
Specifications subject to change without notice.
