Abstract

The invention discloses a high-torque motor. The high-torque motor comprises a motor base and a motor cover body. The motor cover body is internally provided with a motor coil. A core rod is arranged in the center of the motor coil. A connecting screw rod is arranged on the top of the motor cover body. The core rod comprises a rod-shaped core rod body. A first limiting annular groove is formed in the middle of the core rod body. A second limiting annular groove is formed in the bottom of the core rod body. The distance between the first limiting annular groove and the second limiting annular groove is larger than the thickness of the motor coil. The first limiting annular groove and the second limiting annular groove are respectively provided with a separable isolation clamping piece. According to the high-torque motor, by the utilization of the isolation clamping pieces which are made of fluorine nylon and arranged on the first limiting annular groove and the second limiting annular groove, the motor coil can be buckled in a fastened mode, axial movement of the coil is effectively prevented, and reliability and stability of the motor are greatly improved.

Description

High-torque motor

Technical Field

The invention relates to an electromechanical device, in particular to a high-torque motor.

Background

The motor is a very common power driving device, and is generally classified into high speed, high torque and the like. Particularly for a high-torque motor with high power, when the torque of the core rod is close to the limit, the coil is easy to slightly move in the axial direction, high-voltage electric arcs are easy to occur, and the coil is easy to burn out.

Disclosure of Invention

The invention mainly solves the technical problems in the prior art, and provides a high-torque motor.

The technical problem of the invention is mainly solved by the following technical scheme:

the utility model provides a high motor of turning round, high motor of turning round contain a motor base and the motor cover body, the internal motor coil that is equipped with of motor cover, motor coil's center be equipped with a core bar, the top of the motor cover body be equipped with a connecting screw rod, the core bar contain a shaft-like core bar main part, the middle part of core bar main part be equipped with a first spacing annular, the bottom of core bar main part be equipped with the spacing annular of second, the spacing of first spacing annular and the spacing annular of second be greater than motor coil's thickness, first spacing annular and the spacing annular of second on be equipped with a separable isolation clamping piece respectively.

In a preferred embodiment of the present invention, the isolation clip comprises a C-shaped clip body, and a core rod through hole and a pair of heat dissipation air holes are formed in the center of the clip body.

In a preferred embodiment of the present invention, the isolation clip is made of nylon.

The high-torque motor can firmly buckle the motor coil by utilizing the isolation clamping pieces made of the fluorine nylon on the first limiting ring groove and the second limiting ring groove, effectively prevent the coil from axially moving, and greatly improve the reliability and the stability of the motor. The high-torque motor is simple in structure, low in cost, obvious in effect and high in practicability.
