Embodiment Construction

[0026] Attached below Figures 1 to 6 The present invention is described further:

[0027] A motor rotor, the motor rotor 1 includes a rotating shaft 11 and a rotor main body 12 arranged on the rotating shaft 11, the rotor main body 12 includes an inner core 121 and several magnetic tiles 122 distributed on the outer peripheral surface of the inner core 121, the The two ends of the rotor main body 12 are covered with end caps 13, and the circumferential direction of the end caps 13 has an annular flange 130 and the annular flange 130 encloses the magnetic tile 122, and the two end caps 13 An annular groove 9 is formed between the annular flanges 130 so that part of the magnetic tile 122 is exposed. The annular flange 130 of the end cover 13 can wrap the magnetic tile 122, thereby avoiding the falling off of the magnetic tile, ensuring the stability of the product, and making the motor rotor of the present invention firmly assembled; the annular groove 9 makes part of the magn...

Abstract

The present invention discloses a motor rotor, a sewing machine energy saving motor by employing a motor rotor and a sewing machine of a motor rotor. The motor rotor comprises a rotating shaft and a rotor main body arranged on the rotating shaft, the rotor main body comprises an inner core and a plurality of magnetic tiles distributed at the outer peripheral face of the inner core, end caps covertwo end faces of the rotor main body, annular flanges are arranged at the circumferences of the end caps and are configured to wrap the magnetic tiles, and an annular groove which allows part of the magnetic tiles to be exposed is formed between the annular flanges of the two end caps. The annular flanges of the two end caps can wrap the magnetic tiles so as to avoid shedding of the magnetic tiles, ensure the stability of products and allow the motor rotor to be firmly assembled; and moreover, the annular groove allows part of the magnetic tiles to be exposed so as to reduce the influence of the end caps on the magnetism of the magnetic tiles.

Description

【Technical field】 [0001] The invention relates to a motor rotor, a motor and a sewing machine. 【Background technique】 [0002] The existing motor rotor mainly includes a rotating shaft, an annular inner core, and magnetic tiles arranged outside the annular inner core. The magnetic tiles are generally bonded to the peripheral surface of the annular inner core with glue, which is troublesome for workers to operate. At the same time, if the amount of glue used is insufficient, the magnetic tile may fall off, causing damage to the motor. 【Content of invention】 [0003] In order to solve the above problems, the present invention provides a motor rotor. The motor rotor of the present invention has a simple structure, which can ensure that the magnetic tiles are not easy to fall off, is assembled firmly, and is easy to manufacture. At the same time, the invention provides an energy-saving sewing machine motor and sewing machine including the motor rotor of the invention, which h...
