The invention provides a stator capable of suppressing copper loss and a motor, the motor stator comprises a stator core and a winding, and the length direction of the winding is consistent with the axial direction of the motor stator; the two opposite sides of the winding in the thickness direction of the winding are the first side and the second side respectively, and the thickness of the winding changes in the width direction of the winding. The first sides of the two windings can face each other so as to be paired into equal-thickness winding pairs; the second sides of the two windings can face each other so as to be paired into a thickened winding pair; in the radial direction of the motor stator, a plurality of equal-thickness winding pairs and / or a plurality of variable-thickness winding pairs are arranged in stator grooves of the stator core. In the direction from the yoke ring of the stator core to the notch of the stator groove, the groove width of at least part of the stator groove is gradually reduced, and the groove width of the stator groove is matched with at least one of the thickness of the variable-thickness winding pair, the thickness of the equal-thickness winding pair and the width of the equal-thickness winding pair. And through a multi-group winding pairing mode, alternating current copper loss under high frequency is effectively inhibited, and the efficiency of the motor is further improved.
