Description

Technical Field

[0001] The utility model relates to the technical field of motor stator coil structures, in particular to a high-performance stator coil structure for a high-power wind power motor. Background Art

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It uses an energized coil to generate a rotating magnetic field and acts on the rotor to form a magneto-electrodynamic rotating torque. The electric motor is mainly composed of a stator and a rotor. The direction of the force movement of the energized wire in the magnetic field is related to the direction of the current and the direction of the magnetic flux lines. The working principle of the electric motor is that the magnetic field acts on the force of the current, causing the motor to rotate.

[0003] For example, the announcement number is N219351442U, and the name of the Chinese authorized patent is (a high-performance servo motor stator structure), including: a base body, a rectangular opening is opened on the top of the base body, and an installation mechanism is provided in the inner cavity of the base body. Through the mutual cooperation of the damper, shock-absorbing spring, hinged rod, sliding plate, fixed plate, telescopic rod and reset spring, when the base body moves downward, by squeezing a number of dampers and shock-absorbing springs, the adjacent sliding plates are pushed to move to the side away from each other under the limit of the second slide groove and the second slider through two adjacent hinged rods, squeezing the adjacent telescopic rods and reset springs, so as to facilitate the shock absorption of the brushless motor body and extend its service life. Through the mutual cooperation of the servo motor, gear roller, rack plate, connecting block, limit plate, second connecting plate, first connecting plate and card block, the brushless motor body can be easily installed, reducing the work intensity of the staff.

[0004] However, when assembling and installing the stator in the existing motor, the coil will be wrapped around the outer wall of the stator connecting rod. As time goes by, the coil will fatigue, resulting in the problem of the coil being loose and not secure. Therefore, it does not meet the existing needs. In this regard, we propose a high-performance stator coil structure for high-power wind turbines. Utility Model Content
