F897, magnetic laminate, non-insulation laminated sheet with magnetic conductivity. Composed by E-glass fabric impregnated with epoxy resin, adding iron power by processing under high temperature and pressure. It has high mechanical strength, and good heat resistance. Usually used as magnetic slot and wedge for motor and generator. It can transform magnetic circuit, improve the electromagnetic properties and working efficiency, reduce motor loss and noise, control temperature rising and save more energy.
Product Application
F897, magnetic laminate, can be used as magnetic slot wedge. Magnetic slot wedges are widely used in high-voltage motors (such as industrial high-power asynchronous motors) and low-voltage high-power three-phase asynchronous motors to seal the stator slot openings. By reducing the air-gap magnetic resistance, improving the magnetic field distribution, reducing stray losses, and enhancing efficiency (such as increasing efficiency by 1-2%);
In the energy-saving renovation of old motors, magnetic laminates significantly reduce no-load current and operating temperature by replacing traditional slot wedges, improve energy efficiency and reduce carbon emissions (each motor can save hundreds to thousands of kilowatt-hours of electricity annually).
FAQ
FAQ
Q: 1.What are the differences between molding and drawing processes?
A: Molding process: High magnetic permeability and high strength (bending strength ≥400MPa), but relatively high cost, suitable for precision motors.
Drawing process: It has excellent longitudinal strength and low cost, making it suitable for mass production, but its transverse strength is relatively weak.
Q: What are the differences between magnetic laminates and traditional insulating materials?
A: Traditional materials (such as epoxy resin wedges) only serve to insulate and fix, while magnetic laminates can actively adjust the magnetic field, reduce magnetic resistance and loss, and enhance equipment efficiency.
