Product Information

If it is only the CHANGE IN magnetic flux that is taken into account, why would it make a difference if I was using a 2x1x1/2 magnet or a 2x1/2x1/2? For extensive technical information on recommended speeds and feeds see the end of the article. Now you know how, why would you want to ream a hole? It was a desire to provide a solution to these challenges that led us to create two brand new products - Enter the VersaDrive and ImpactaMag range of construction and fabrication reamers. VersaDrive Impact Reamers

The ImpactaMag™ HSS reamer is a unique double-use reamer for enlarging and aligning holes in metals and hard materials. To maximise tool life do not attempt to increase the existing hole diameter beyond 2-3mm. If a larger, finished hole size is required, then the next size reamer should be used to ‘step up’ until the finished hole diameter is reached. http://www.researchgate.net/publication/224606165_High-speed_axial-flux_permanent-magnet_generator_with_coreless_stator The correct tool for the job will depend on the drive tool you are able to use, the size of the final hole required and the material you are reaming. When VersaDrive reamers are the best option:VersaDrive reamers are the perfect hole alignment and enlarging tool for metalworkers & steel erectors for keeping the job moving when a hole is misaligned or the incorrect size for the fixing. Note that in real-world applications this is not always the case. Economics often matters more than sheer performance per size. Washing machine makers who implement direct drum drive brushless DC motors (with the Fisher & Paykel (now Haier) smartdrive as a superb example) often choose to use ferrite magnets with a consequent larger coil size and so larger diamter rotor and overall machine dimensions as a consequence. The tapered design allows the narrow end of the ImpactaCut reamer to be entered into the existing hole and accurately centred.

DSc thesis - DESIGN OF AXIAL-FLUX PERMANENT-MAGNET LOW-SPEED MACHINES AND PERFORMANCE COMPARISON BETWEEN RADIAL-FLUX AND AXIAL-FLUX MACHINES Specially designed cutting geometry allows the tool to be used in an Impact wrench or a Magnet drill. When used in an Impact wrench it is secured into a special adapter meaning the tool is easier to control, apply correct feed rate, and withdraw from the finished hole, enhancing tool life. This reamer will also fit into a standard Weldon magnet drill arbor.Secondly, assuming you already have a hole you wish to enlarge or align choose the most appropriate reamer for the size of hole you need. For example, if you are wishing to go from an 8mm hole to a 16mm hole it is not advisable to do that in one operation. For best results, and to prevent tool breakage, enlarge the hole in small increments of 2-3mm at a time, using the appropriate sized reamer to do this. The maximum uniform pull happens when one end of the plunger is at the middle of the solenoid. An approximation for the force F is [8] F = C A N I / ℓ {\displaystyle F=CANI/\ell } His first electromagnet was a horseshoe-shaped piece of iron that was wrapped with about 18 turns of bare copper wire ( insulated wire didn't then exist). The iron was varnished to insulate it from the windings. When a current was passed through the coil, the iron became magnetized and attracted other pieces of iron; when the current was stopped, it lost magnetization. Sturgeon displayed its power by showing that although it only weighed seven ounces (roughly 200 grams), it could lift nine pounds (roughly 4 kilos) when the current of a single-cell power supply was applied. However, Sturgeon's magnets were weak because the uninsulated wire he used could only be wrapped in a single spaced out layer around the core, limiting the number of turns. Insert reamer into the hole to be enlarged. VersaDrive and ImpactaMag reamers are Tapered reamers, otherwise known as Bridge reamers, and will self centre thanks to their sloping, tapered sides. (Reamers used in a magnet drill can only self centre with the magnet turned off so the drill can move to the correct position.)
