Brushless Permanent Magnet Motor Design
|
|
Features Revised and greatly expanded from the first edition. The first three chapters are similar to the first edition, but all later chapters are entirely new. Starts from fundamentals and slowly builds a set of understandable concepts for motor design. This test does NOT assume that you already have years of experience. Over 350 figures, over 400 equations, 408 pages. Illustrates over 50 motor designs ranging from a 2 pole, 3 slot motor to a 32 pole, 36 slot motor. Provides motor cross section, winding layout, and performance details for each design. Presents a winding algorithm for all feasible pole and slot count combinations. Rigorous analytic description of the magnetic field distribution in the magnets and air gap that is applicable to radial field, axial field, and linear motors. Provides comprehensive design equations that take into account, the air gap flux density distribution, the leakage flux from magnet to magnet, stator slotting, steel saturation, arbitrary winding distributions, etc. Defines and discusses topics such as permeance coefficient, armature reaction, cogging torque, skewing, core losses, torque ripple, slot leakage inductance, motor constant, torque constant, back EMF constant, fractional slot, fractional pitch, etc. To
