Problems solved by technology

However, because the teeth of the block stator have edges and corners, that is, the winding circumference is approximately square, it is easy to cause the coil to be wound tightly enough and the space factor is small, especially the thick copper wire has high hardness and is inconvenient to bend, which will cause certain difficulties to pr

Example Embodiment

[0021] The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings:

[0022] Such as Figure 1-3 Shown: 1 is the clamping arm, 2 is the winding ridge, 3 is the outer baffle, 4 is the inner baffle, 5 is the through slot, and 6 is the inner baffle slope.

[0023] The stator winding frame of the present invention includes an arc-shaped winding ridge 2 and clamping arms 1 on both sides. The winding surface of the winding ridge 2 is but not limited to an arc surface. The spacing between the clamping arms 1 on both sides depends on the width of the stator teeth. Fixed, just enough to buckle the stator teeth. Both ends of the winding spine 2 and the clamping wall 1 have an inner baffle 4 and an outer baffle 3. The height of the baffle in the winding direction of the clamping arm 1 and the winding spine 2 is based on the required winding line type and winding Depending on the number of turns, generally the coil should not...

Abstract

The invention discloses a winding skeleton which is sleeved on the stator iron core of a motor, and a method for detecting the number of coil turns of the stator winding by using the skeleton. The winding frame includes an arc-shaped winding ridge and clamp arms on both sides, and a through hole or a through groove parallel to the clamp arm is opened on the back side of the winding surface of the winding ridge. When the frame is buckled on the stator teeth, the The through holes or slots are still open, and there are baffles at the two ends of the winding ridge and the clamping wall. The stator winding frames are used in pairs, and are respectively buckled on the stator teeth at both ends of the stator core block, and are positioned against the stator tooth tips. The fastening surface between the inner baffle plate at one end and the tooth tip of the stator is an inclined plane, and its inclination coincides with the inclined plane of the tooth tip of the stator. The winding skeleton is made of synthetic material of nylon and glass fiber. The use of the winding frame can effectively improve the space factor and winding quality of the stator winding, improve the performance of the motor, and can detect the number of coil turns of a single stator winding.

Description

technical field [0001] The invention relates to a motor winding component, in particular to a winding frame set on the stator core of a motor, and a method for detecting the number of coil turns of the stator winding by using the frame. Background technique [0002] The winding is an important part of the motor. The quality of the winding has a great influence on the performance of the motor. It is the place with the heaviest work and the weakest structure among all the structural parts of the motor. Most of the other parts of the motor are made of steel materials, which are generally less damaged under normal use. The motor winding is different, it is made of insulated wires, and the rotating magnetic field will cause the electromagnetic vibration and heat of the winding when it is energized, making the winding the most vulnerable part. In addition, improper selection of the stator and insulated wires, or misoperation of the motor and failure of the motor system protection...
