Abstract
Description
Technical Field
[0001] This utility model belongs to the field of DC motor technology, specifically relating to a high torque stability DC motor. Background Technology
[0002] Traditional DC motors often face the following problems in high-torque applications: when the motor is running under high load, the support structure is not rigid enough, which can easily cause vibration or displacement, resulting in torque fluctuation. The motor has a single fixing method, which is difficult to adapt to different equipment installation spaces. In addition, the motor has weak vibration resistance, lacks effective heat dissipation design and reinforcement structure, and long-term operation can easily lead to excessive temperature rise or mechanical deformation. Utility Model Content
[0003] The main objective of this invention is to provide a high-torque-stability DC motor. Through a multi-directional support structure, acute-angle connecting plate, and reinforcing rib design, it achieves stable torque output, flexible installation, and efficient heat dissipation, significantly improving the reliability and lifespan of the motor under high-load conditions.
[0004] To achieve the above objectives, this utility model provides a high torque stability DC motor, which includes a DC motor body, support feet on both sides of the DC motor body, mounting holes on the support feet, the support feet being horizontally positioned, and a connecting plate on the inner side of the support feet, the connecting plate fixing the support feet to the side of the DC motor body.
[0005] The high-torque stability DC motor provided by this utility model features a horizontal support foot plate that provides multiple fixing points, reducing vibration amplitude and ensuring stable torque output. The standardized design of the mounting holes adapts to various installation scenarios, improving the flexibility of equipment integration.
[0006] In one possible implementation, the connecting plate includes a first connecting plate and a second connecting plate, which are arranged at acute angles. The acute angle design enhances the shear resistance of the connecting plate, improves the connection strength between the support foot and the motor body, and simultaneously disperses stress concentration, preventing fatigue fracture at the connection point due to high-frequency vibration.
[0007] In one possible implementation, a front cover is provided on the front side of the DC motor body, and the front cover is fixed by a fixing rod that passes between the first connecting plate and the second connecting plate. The gap between the rod and the connecting plate is designed to allow for thermal expansion space to avoid structural deformation at high temperatures.
[0008] In one possible implementation, reinforcing ribs are provided on the sides and top surface of the DC motor body. These ribs enhance the bending strength of the housing and prevent deformation caused by high torque.
[0009] In one possible implementation, the bottom of the DC motor body is provided with a bottom reinforcing rib, the bottom surface of which is higher than the position of the supporting foot plate. The bottom rib forms a suspended heat dissipation channel, enhancing air convection efficiency and further optimizing heat dissipation performance. Attached Figure Description
