The invention relates to a motor stator, a motor with the motor stator and a manufacturing method of the motor stator. The motor stator comprises a stator iron core, wherein the stator iron core comprises a plurality of block iron cores matched in the circumferential direction, each block iron core is provided with stator teeth extending inwards in the radial direction of the stator iron core, a wire groove is formed between every two adjacent stator teeth, and the width L of a groove opening of each wire groove meets the condition that L is larger than 1.5 mm and smaller than 2.4 mm. According to the motor stator provided by the embodiment of the invention, the stator iron core can be wound in an internal winding mode to form the stator winding by utilizing the winding machine after the block iron cores are assembled, the coil can also be formed in an external winding mode before the block iron cores are assembled, and the coil is further connected to form the stator winding after theblock iron cores are assembled; therefore, the motor stator in the embodiment meets two different production modes, the equipment utilization rate can be improved, and production efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of motors, in particular to a motor stator, a motor having the same, and a manufacturing method of the motor stator. Background technique [0002] In the related art, the stator core of the motor stator mainly has two forms: integral type and segmented type. Integral stator core, the slot between the stator teeth is larger, the stator winding adopts the inner winding method, and for two-phase or multi-phase motors, each phase winding can be wound continuously to form less wire ends and wire tails for easy wiring. Compared with the integral stator core, the segmented stator core is assembled from segmented cores. The segmented stator core has the advantages of high material utilization and material saving during manufacturing, but due to the The size of the notch between the rear stator teeth is small, and the segmented stator core can only wind the individual segmented cores separately, and then splice the...
