Problems solved by technology

However, after the early domestic motor factories used magnetic slot wedges, the motor ran for a period of time, and the magnetic slot wedges suffered from loose organization, surface bubbling and even cracking, so until now, the use of magnetic slot wedges has been stopped.

Embodiment Construction

[0008] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0009] like Figure 1 ~ Figure 2 As shown: the present invention is mainly composed of a stator punch 1, an upper stator coil 2, a lower stator coil 3, a magnetic slot wedge 4, a top pad 5, a middle pad 6, an adjustment pad 7, and an expansion pad 8.

[0010] The motor with the magnetic slot wedge device includes an upper stator coil 2 and a lower stator coil 3 arranged in the stator punch 1, a magnetic slot wedge 4 is arranged below the lower stator coil 3, and the top surface of the upper stator coil 2 and the stator punch 1. A top pad 5 is provided between the bottom and top, a middle pad 6 is provided between the top surface of the lower stator coil 3 and the bottom end surface of the upper stator coil 2, and a middle pad 6 is provided between the bottom end surface of the lower stator coil 3 and the bottom frame of the stator punch 1. There are an adjustm...

Abstract

The invention relates to a motor stator component structure with a magnetic slot wedge, which is characterized by comprising an upper stator coil and a lower stator coil which are arranged in a stator punching; the magnetic slot wedge is arranged below the lower stator coil, a top cushion is arranged between the top end surface of the upper stator coil and the bottom roof of the stator punching, a middle cushion is arranged between the top end surface of the lower stator coil and the bottom end surface of the upper stator coil, an adjustment cushion and an expansion cushion are arranged between the bottom end surface of the lower stator coil and the bottom frame of the stator punching, the adjustment cushion is arranged below the expansion cushion, and the top end surface of he magnetic slot wedge is in contact with the bottom end surface of the adjustment cushion. The magnetic slot wedge of the invention can effectively improve the magnetic potential wave shapes of air gaps, reduce exciting currents, increase the power factors and efficiency of a motor, and reduce the temperature rise, noise and vibration of the motor. The magnetic slot wedge can ensure that the motor can be reliably fixed in the stator slot shape during the operation process without phenomena of loosing, cracking, tissue loosing, surface bubbling and the like, thus avoiding the friction between the stator and the rotator of the motor caused by the cracking, loosing, dropping and the like of the magnetic slot wedge.

Description

technical field [0001] The invention relates to a motor stator component structure, in particular to a motor stator component structure with a magnetic slot wedge device. Background technique [0002] At present, the international energy is becoming more and more tense, and energy saving is becoming more and more important. If magnetic slot wedges are used, for high-voltage motors with open slots in the stator, the loss can be significantly reduced, the efficiency can be improved, and the temperature rise of the motor can be reduced (the motor temperature rise of the magnetic slot wedge is about 18% lower than that of the non-magnetic slot wedge), Reduce noise. However, after the early domestic motor factories used magnetic slot wedges, the motors ran for a period of time, and the magnetic slot wedges suffered from loose organization, surface bubbling and even cracking, so until now, the use of magnetic slot wedges has been stopped. Contents of the invention [0003] The...
