A permanent magnet motor is a type of electric motor that uses permanent magnets for the field excitation and a wound armature. The permanent magnets can either be stationary or rotating; interior or exterior to the armature for a radial flux machine or layered with the armature for an axial flux topology.
KS Steel is a permanent magnetic steel with three times the magnetic reluctance of tungsten steel, which was developed in 1917 by the Japanese scientist and inventor Kotaro Honda. "KS" stands for Kichizaemon Sumitomo , the head of the family-run conglomerate, who provided financial support for the research leading to KS Steel's invention.
Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.
A permanent-magnet synchronous motor (PMSM) uses permanent magnets embedded in the rotor to create a constant magnetic field. The stator carries windings connected to an AC electricity supply to produce a rotating magnetic field (as in an asynchronous motor). At synchronous speed the rotor poles lock to the rotating magnetic field.
The teeth function as alternating magnetic poles. The rotor’s magnetic poles interact with the alternating magnetic flux of the teeth, producing torque. [1] The use of grain-oriented steel in radial flux motors is challenging due to the curving geometry of the magnetic flux path. [2]
