PROBLEM TO BE SOLVED: To provide a synchronous rotating electric machine having a permanent magnet shape capable of suppressing the saturation of q-axis magnetic flux, improving the use of reluctance torque, contributing to enhancement of magnet torque, obtaining a large torque at the time of starting and in a sudden change in load and being efficient, in an iron core formed between the upper end surface of magnet holes arranged in two V shape and the outer circumference of a rotor and a vehicle, an elevator, a fluid machine and a processing machine equipped with such synchronous rotating electric machine. SOLUTION: The synchronous rotating electric machine having a permanent magnet shape is structured as follows. With reference to two magnet holes 2, 3 for inserting two permanent magnets 6, 7 per pole along the V shape, which are provided at a predetermined pole pitch angleθin a rotor core 11, the angle made with the magnet hole 3 making the peak of the V shape as a basis and the center line OC of the pole pitch angleθis made smaller than the angle made with the magnet hole 2 and the center line OC of the pole pitch angleθ, and in a salient pole of a rotor 10 in which the q-axis magnetic flux flows, two salient magnetic poles of a stator 12 are almost facing each other.
