ELECTROMAGNETIC STEEL PLATE FORMER AND ELECTROMAGNETIC STEEL PLATE LAMINATE, AND PERMANENT MAGNET TYPE SYNCHRONOUS ROTATION MOTOR ROTOR AND PERMANENT MAGNET TYPE SYNCHRONOUS ROTATION MOTOR HAVING THE SAME, AND, VEHICLE, LIFT, FLUID MACHINE AND WORKING MACHINE USING THE ROTATION MOTOR

摘要

Provided are an electromagnetic steel plate former and an electromagnetic steel plate laminate, a permanent magnet type synchronous rotator motor rotor and a permanent magnet type synchronous rotation motor having the same, and, a vehicle, a lift, a fluid machine and a working machine using the rotation motor, in which the saturation of a q-axis magnetic flux is suppressed by an iron core portion formed between the upper end faces of magnetic holes arrayed in two V-letter shapes and the outer circumference of a rotor, thereby to utilize a reluctance torque and to improve the magnetic torque, so that a high torque can be efficiently acquired at a starting time or in an abrupt load fluctuation. Of the two magnetic holes (2) and (3) for inserting two permanent magnets (6) and (7) for one pole along a V-letter, within the range of radial polar pitch lines (OP) arranged at a predetermined polar angle (ϑ) in a rotor core (11), one magnetic hole (2) is deviated in a direction apart from the center line (OC) of the polar pitch lines (OP), but the other is deviated in a direction toward the center line (OC) of the polar pitch lines (OP).
