Magnetizer
Magnetizer, also known as pulse magnetizing power supply, is core specialized equipment in permanent magnet manufacturing. This model integrates both magnetizing and demagnetizing functions, widely used for magnetization of sintered NdFeB, ferrite, AlNiCo and other permanent magnets. It is the key equipment to convert non-magnetic blanks into magnetized finished magnets.
Working Principle
High-voltage energy storage capacitors inside the unit accumulate electric energy and instantly release huge pulse current into the magnetizing coil. The coil rapidly generates a high-intensity directional pulsed magnetic field. Under this strong field, randomly arranged magnetic domains inside the magnet align uniformly, granting the magnet stable and persistent remanence to complete saturation magnetization. The machine can output alternating decaying magnetic field for magnet demagnetization, meeting requirements such as product rework and performance testing.
Main Applications
Perform saturation magnetization on non-magnetic magnets after precision machining and electroplating to endow rated magnetic properties and produce usable permanent magnet finished goods.
With custom dedicated magnetizing fixtures, it supports axial, radial, multi-pole and skew-pole directional magnetization processes, suitable for manufacturing motor magnets, ring magnets, electronic magnetic sheets, speaker magnets and diversified products.
Demagnetize defective workpieces for re-grinding rework and re-magnetization; also used for degaussing pre-treatment before magnetic performance inspection.
Support single sample trial production and tray-based continuous batch magnetization, fitting the rhythm of large-scale industrial continuous production.
Equipment Advantages
Continuously adjustable magnetic field strength, compatible with regular grades and high-coercivity high-temperature resistant NdFeB to guarantee full saturation magnetization.
Stable and controllable pulse output energy, small magnetic force deviation within batches, high magnetization uniformity and excellent product consistency.
Combined magnetizing & demagnetizing in one unit to reduce equipment investment, covering mass production, rework and commissioning scenarios.
Quick fixture replacement to switch production between different sizes, flexible for multi-category, small-batch and large-batch orders.
Multiple safety protections including overvoltage, overcurrent, high-voltage shielding and emergency stop interlock. Stable operation under high-current working conditions with high safety.
Continuous operation heat dissipation design, low heat buildup under long-duration frequent magnetization cycles, low failure rate and extended service life.
