The U-series (High Current Impulse Magnetizer IM-U-1420-A-HC)

Data Sheet Datenblatt

Description

The impulse magnetizer IM-U-1420-A-HC operates according to the principle of capacitor discharge. The inner construction of the magnetizer has been optimized so that impulses of 60000 Amperes, with only 1400 Joules of energy, can be produced.

The magnetization of small rare-earth magnets requires especially high currents in thin wires. If these magnetization fixtures are operated with traditional standard magnetizers they run the risk of overheating.

This impulse magnetizer is especially suitable for the operation of this type of sensitive magnetization fixtures because very high currents are produced at very short impulses. The use of this impulse magnetizer offers the following advantages:

• Better magnetizing results
• Higher current in the magnetization fixture
• Less heating of magnetization fixture
• Longer lifetime of magnetization fixture
• Shorter duty cycles in production

Safety functions

Safety is a key area for Magnet-Physik. Operation without interruption and protection of the operator is a primary concern.

All basic functions are controlled continuously by the PLC. The voltage at the capacitor banks are monitored by the PLC and additionally by a separate circuit. In case of a fault or interruption from mains the capacitors are discharged automatically. The magnetizers are equipped with two of these circuits. The PLC also monitors the charging unit and in case of a failure it separates it from the mains and controls the automatic capacitor discharge.

Magnet-Physik fixtures are equipped with thermocouples that allow monitoring of the fixture heat. A second internal switch also will open should excessive heat build up.
