Description

Technical Field

[0001] This utility model relates to the field of permanent magnet synchronous traction control, specifically a permanent magnet synchronous traction control device. Background Technology

[0002] In vertical transportation equipment such as elevators, permanent magnet synchronous traction control devices play a crucial role. The traction machine is the core component of the elevator's electric drive system, and its main function is to convert the rotational motion of the motor into the linear motion of the elevator car. It consists of a permanent magnet synchronous motor, a traction sheave, and a braking system. The permanent magnet synchronous motor uses high-performance permanent magnet materials and a special motor structure, and has characteristics such as energy saving, environmental protection, low speed, and high torque. The traction sheave and the brake sheave are coaxially fixedly connected and use double-point support.

[0003] In terms of structural design, the installation and connection of the internal components of the equipment are not modular enough, which makes the disassembly and assembly process cumbersome during inspection and maintenance, consuming a lot of time and manpower, seriously affecting the maintenance efficiency of the equipment. The heat dissipation performance also needs to be improved. Traditional heat dissipation methods are often unable to effectively deal with the heat generated by the equipment during operation, especially under long-term continuous operation or high-load conditions. Excessive temperature will cause the performance of permanent magnet synchronous motor and control module to degrade, or even cause failure, reducing the stability and reliability of the equipment. To address this, we have proposed a permanent magnet synchronous traction control device. Utility Model Content

[0049] Working principle: The housing 1 is fixedly installed in the required position by the support 3, providing stable support for the operation of the equipment. The base of the permanent magnet synchronous motor 10 is fixed to one side of the housing 1 with bolts and nuts to ensure the stability of the motor. At the same time, the main shaft of the traction machine 9 is coaxially connected with the output shaft of the permanent magnet synchronous motor 10 to ensure smooth power transmission. The control module 16 is installed on the mounting plate 18. The mounting frame 25 is inserted into the socket 21 by sliding the slider 19 on the second mounting frame 5 with the slot 13 on the top surface of the housing 1. This positions the control module 16 between the permanent magnet synchronous motor 10 and the cooling fan structure. In the cooling fan structure, the cooling fan 21 is fixed in the mounting frame 1 4 separated by the cross partition 20. The slider 19 is also fixed in the mounting frame 1 4 with the slot 13. The mounting frame 4 is inserted into the socket 12. Finally, the two protective covers 2 are hinged to the symmetrical sides of the opening of the housing 1. At this time, the traction sheave of the traction machine 9 and the manual brake release wrench are located between the protective covers 2. The traction hole 8 on the protective cover 2 connects the traction sheave to the outside, preparing for the subsequent installation and operation of the traction rope. When the elevator needs to run, the control module 16 sends an electrical signal to the permanent magnet synchronous motor 10 through wiring. The permanent magnet synchronous motor 10, with its high-performance permanent magnet material and special motor structure, converts electrical energy into mechanical energy, and the output shaft starts to rotate, driving the main shaft of the traction machine 9 to rotate, which in turn causes the traction sheave to rotate. The friction between the traction sheave and the traction rope drives the elevator car to move in a straight line, realizing vertical transportation. During operation... The control module 16 continuously monitors the elevator's operating status, such as speed and position parameters. Based on preset operating logic and signals from various sensors, it adjusts the electrical signals sent to the permanent magnet synchronous motor 10 in real time, precisely controlling the motor's speed, torque, and other operating parameters to ensure smooth elevator operation and accurate stopping. During operation, components such as the permanent magnet synchronous motor 10 and the control module 16 generate heat. At this time, the cooling fan structure starts working. After being powered on, the cooling fan 21 rotates, generating airflow. Outside air enters the housing through the heat dissipation holes 22, flows over the permanent magnet synchronous motor 10 and the control module 16, and carries away the heat. The ventilation holes 17 on the mounting plate 18 help the air circulate better, enhancing the heat dissipation effect. Hot air passes through the cooling fan... Under the action of fan 21, the exhaust is discharged from the other side of the casing, thereby ensuring that the equipment operates within a suitable temperature range and maintaining the stable performance of each component. During normal operation, the outer shell structure composed of casing 1 and protective cover 2 protects the internal components such as traction machine 9, permanent magnet synchronous motor 10, and control module 16, preventing dust and debris from entering and ensuring the normal operating environment of the equipment. The switch hole 15 on the side of the protective cover 2 corresponding to the manual brake release wrench of traction machine 9 connects the manual brake release wrench to the outside. The rubber sheet 7 serves as a dustproof function, and the sliding hole 14 facilitates the swinging of the manual brake release wrench. When the elevator needs maintenance or an emergency occurs, maintenance personnel can operate the manual brake release wrench through the sliding hole 14 to overcome the braking force of the braking system and manually release the brake.This is so that operations such as manual rotation of the elevator can be performed.
