An electric motor is an electrical machine that converts electrical energy into mechanical energy.Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. Ideally, this resistance should be infinite. This is particularly true for parts with narrow sections, or where very high flux density is requiredCommonly Used Magnet Materials MaterialMagnetic PropertiesMagnetic CharacteristicsCurie TemperatureTemperature Coefficient of InductionCost $ / lb.Cast AlnicoBr – 5,500 – 13,500 Hc – 475 – 1,900 MGOe 1.4 – 10.5Cast to Shape, Hard, Crystal Structure – Grind or EDM840°C0.02% / °C$40Sintered AlnicoBr – 6,000 – 10,800 Hc – 550 – 1,900 MGOe 1.4 – 5.0Powder Pressed to Shape, Hard Structure – Grind or EDM840°C0.02% / °C$23Ceramic (Hard Ferrite)Br – 3,450 – 4,100 Hci – 3,000 – 4,800 MGOe 2.7 – 4.0Simple Shapes: Arcs, Rect., Plugs, Rings – Hard-Grind450°C0.02% / °C$2Samarium CobaltBr – 8,800 – 11,000 Hci – 11,000 – 21,000 MGOe – 18 – 32Very Brittle – Grind or EDM750°C / 825°C0.035% / °C$125Neodymium Iron BoronBr – 10,500 – 14,000 Hci – – 14,000 MGOe 27 – 50Requires Coating to Prevent Oxidization Grind or EDM310°C0.13% / °C$95Iron-Chrome CobaltBr – 9,000 – 13,500 Hc – 50 – 600 MGOe – 4.25 – 5.25Can be Formed, Stamped, Thin Rolled Mat’l 0.050″- .0005″600°C0.02% / °C$30Bonded Flexible (Callenered or ExtrudedBr – 2,500 – 5,600 Hci – 3,500 – 16,000 Ferrite 450°C 0.18% / °C $3 MGOe 1.4 – 6.2Flexible, Thermal Shock Resistant, Low-tono Tooling Charge, Available In Wide Range of SizesFerrite 450°C Neo 310°C0.18% / °C 0.07 to 0.13% / °C$3 $30 – $50Bonded Plastic (Molded)Br – 2,500 – 6,900 Hci – 3,000 – 16,000 Ferrite 450°C 0.18% / °C $3 MGOe – 1.5 – 10.5Complex Shapes, Thin Walls, Tight Dimensions without Machining, Good StrengthFerrite 450°C Neo 310°C0.18% / °C 0.07 to 0.13% / °C$3 $60Compression Bonded Neo (Epoxy)Br – 6,200 – 8,200 Hci – 4,300 – 18,000 MGOe – 7.5 – 15.0Simple Geometry, Close Tolerancing W.O Machining Higher BhMax Than Inj. Current flowing through copper wire coil windings wrapped around an iron core (stator) creates an electro-magnetic field that either opposes or attracts the magnetic field provided by permanent magnets mounted to a … Twisting wires together using a pair of household slip-joint pliers is difficult, and the loose connection might come apart. The measurement of partial discharges can also provide information on: points of weakness in the insulation system; ageing processes; further measures and intervals between overhauls. 1.A.1 Shaded-Pole Induction Motors. Consequently, there is an urgent need to give some guidance to those users who are considering the use of PD measurements to assess the condition of their insulation systems. Step 3. The two forces create a torque which causes th… When the field coil is energized, it creates a magnetic field (excitation flux) in the air gap, in the direction of the radii of the armature. Compared with other dielectric tests (i.e. A standard test voltage is applied (below the established Breakdown Voltage) and the resulting leakage current is monitored. motors. The test voltage is increased until the dielectric fails, or breaks down, allowing too much current to flow. Wiring Diagrams for 2-way Switches, 3-way Switches, 4-way Switches, Outlets and More. In order to understand even the simplest concepts of electronics, you must first understand what electricity is. The conductors located under the other pole are subject to a force of the same intensity in the opposite direction. It uses a symbolic language on engineering drawings and computer-generated three-dimensional solid models that explicitly describes nominal geometry and its allowable variation. Because of its lower electrical conductivity, aluminum wire requires a 1.6-times larger cross sectional area than a copper wire to achieve comparable DC resistance. The stresses introduced during punching degrade the material properties around the edges of the lamination, and must be removed to obtain maximum performance. Modern magnet wire typically uses one to four layers of polymer film insulation, often of two different compositions, to provide a tough, continuous insulating layer.
