Magnetic Slot Wedges
Slot Wedges
Magnetic and non Magnetic Slot Wedges
SPInduwedge Slot Wedges are made of either magnetic or nonmagnetic Material, being used as Slot Closures to hold the stator windings in the slots formed between the stator teeth.
Slot wedges made of magnetic material are a significant means to improve the efficiency of a motor or generator. Magnetic slot wedges reduce slot ripple in the air gap flux caused by the changing reluctance due to the slots, and also reduce the associated eddy current losses due to the interaction of the harmonics in the air gap flux with the conducting surface of the rotor.
The magnetizing current required in the stator windings to generate the desired air gap flux is less with magnetic slot wedges, since more of the air gap flux is available for useful power production.
Replacement Magnets for HO slot carrs. Spend $150.00 or more on select items to receive FREE Shipping for orders to United States. Magnetic Mail Slot Cover includes a flexible magnetic sheet material which allows mail to be easily placed through slot openings with little resistance. The sheet then closes shut immediately to prevent any air drafts created by typical exterior mail slot doors. The best on the market by far, No visible lugs, Great design, In depth instructions. Scalextric/Slot Car Buildings & Accessories 1:32 scale.
Magnetic slot wedges reduce starting current, improve cos phi and load current, and lead to reduced iron loss (core loss).
Typical reduction of iron loss is in the range of some kW depending on the type of machine. This means a corresponding
value of some thousand Euros, when calculating the machine prize. So it is obvious that additional costs for high performance
slot wedges clearly pay off.
Conventional slot wedges are that weak that they often are not fulfilling the mechanical needs so that some companies are
not using magnetic wedges any more.
The mechanical properties of SPInduwedge – a new generation of magnetic slot wedges – are surpassing that of conventional
magnetic slot wedges (made out of laminated material) by far and it is to mention that they are in the range of non
magnetic (i.e. unfilled) glass fiber reinforced material, some non magnetic material they are even surpassing.
Further, our magnetic Slot wedges are not produced from Sheets which means a massive Improvement since cutting and grinding of Sheets with High Glass Content has a Major Impact on Health.
SPInduwedge (magnetic) Temperature Class F HP
Properties
SPInduwedge F [HP] – High Performance, is a rolled and pressed slot wedge made of special epoxy glassfibre ironpowder prepreg which has good magnetic conductivity and high electrical and thermal resistance combined with excellent mechanical strength.
Application
Magnetic slot wedges are used for example as induction motor, wind generator and traction motor – slot closure key.

SPInduwedge (magnetic) Temperature Class H (HP)
Properties
SPInduwedge H [HP] – High Performance, is a rolled and pressed slot wedge made of special epoxy glassfibre ironpowder prepreg which has good magnetic conductivity and high electrical and thermal resistance combined with excellent mechanical strength.
Application
Magnetic slot wedges are used for example as induction motor, wind generator and traction motor – slot closure key.

Slotwedge Information Folder & Test Results
- Information folder about the unique advantages and properties of SPInduwedge Magnetic slot wedges.
- Our Magnetic slot wedges have been extensively tested for their mechanical properties at the Technical University of Vienna.
to prove the stability of SPInduwedge and to compare the mechanical data with conventional magnetic slot wedges. The results of this investigation are shown in the diagrams of this folder and in an descriptive 23-page booklet (Technical Report), which can be downloaded here.
This extremely high flexibility is a result of SPI's patented Production Process. If you try this with any Competitors Wedge, it will most likely break or delaminate.
Our Furnace Filter Magnetic Slot Seal is the answer to this question. Our air-sealed cover has been specifically designed to eliminate energy loss and stop allergens and pollutants from entering the furnace at the filter.
Benefits:Energy Savings
Saves Energy - Reduces Utility Bills
Improves Indoor Air Quality
Increases Furnace and A/C Lifespan
Lightweight.
Maintenance free.
Magnetically Attaches to Ductwork - Quick and Easy
Blocks allergens and other contaminants, including deadly gases like carbon monoxide and radon from entering the HVAC system at the air filter slot.
Universal one size fits all
Reusable, easy on / easy off design
Magnetically attaches to the duct work
Two-piece design works with any 1' filter up to 25' long
FilterLock® is a patented two-piece system designed for use with 1-inch air filters that eliminates air leakage at the filter slot/door to improve indoor air quality (IAQ) and reduce energy consumption. Energy Star lists air leakage at the filter slot as one of four major issues with duct work in the home.
If not properly sealed, harmful airborne contaminants can enter the heating, ventilating and air conditioning (HVAC) system through the filter slot/door and bypass the air filter. FilterLock® installs in seconds with no tools to eliminate unfiltered air from entering the system through the filter slot/door. Since dirty air that leaks into the HVAC has to be conditioned, FilterLock® can also reduce energy consumption. Built-in magnet fasteners hold FilterLock® securely in place, and it is re-usable indefinitely.
