Problems solved by technology

If there are only N or S poles on the outer surface of each magnetic steel, then when the rotor is running, that is, from N→S or S→N, the gap between the magnetic steel blocks will cause the high-speed running slotted motor to vibrate when changing poles

Embodiment Construction

[0007] The invention is a novel slotted drum motor. The number of magnetic steels 5 on the rotor of the high-speed slotted drum motor is thirteen, and the arrangement is uniformly distributed along the circumference with the iron core 2 as the center. Each magnetic steel has N and S poles at the same time, so that there is no gap and weak magnetic field during the high-speed operation of the rotor. The present invention includes a stator, the stator is composed of a cylindrical coil 13 embedded in the inner ring of the silicon steel sheet 4; the iron core 2, the main magnetic steel 5, the stainless steel sheath 12, and the bracket 14 are combined together, and are supported by the bearing 10 on the seat body. A cantilever rotor is formed in the hole, and the rear cover 9 is closed on the rotor by screws, and then the end face is blocked by the end cover 7. A circuit board support is installed on the rear cover 9, and the positioning detection Hall sensor 11 and the positioning ...

Abstract

The invention relates to a motor, in particular to a novel groove drum motor matched with an automatic winder in the textile spinning industry. The novel groove drum motor comprises a stator formed by embedding a drum-shaped coil into an inner ring of a silicon steel sheet; an iron core, main magnetic steel, a stainless protective sleeve and a bracket are combined together; a bearing is supported in a hole of a seat body to form a cantilever rotor; the motor is provided with a positioning detection Hall sensor and a positioning detection circuit board; and in addition, the motor is also provided with a speed-measuring Hall sensor and a speed-measuring circuit board. A groove drum can be fixed on the iron core through bolts and two rolling bearings; and the motor acquires a direct current pulse signal through a power cord. The invention can ensure that the rotor of the high-speed groove drum motor matched with the automatic winder stably runs in the use process and can solve the domestic difficult problem of the high-speed groove drum motor.

Description

technical field [0001] The invention relates to a motor, in particular to a novel grooved drum motor matched with an automatic winder in the textile spinning industry. Background technique [0002] At present, the grooved drum motors produced in China tend to vibrate when running at high speed. One of the main reasons is that the magnetic steel on the rotor is not uniformly magnetized, and there are weak magnetic points between the poles; the number of magnetic steel pole pairs on the rotor is unreasonable. The magnetic density is not uniform, and the low magnetic density causes the slotted drum motor to fail to meet the requirements of long-term high-speed operation. Especially in the hot summer, the torque is unstable, the rotor rigidity is poor, the rotor beats large, the current is large, and the power consumption is high. Severe fever, high temperature rise and burnt. In order to obtain the high-speed operation of the slotted drum motor, the slotted drum motor must hav...
