Description

Technical Field

[0001] This invention relates to the field of magnetic wheel speed regulation, specifically to an electric regulator for redundant adjustment of magnetic wheel speed regulators. Background Technology

[0002] The main components of the magnetic wheel speed controller include a conductor wheel, a permanent magnet wheel, and a movable base.

[0003] The conductor wheel is mounted on the motor shaft, and the movable base is mounted on the bottom of the motor, driving the motor to move axially. This changes the coupling area between the conductor wheel and the permanent magnet wheel, thereby adjusting the transmitted torque and changing the load's speed. To achieve automatic control of the magnet wheel speed controller, an electric actuator is installed on the movable base to receive control signals from the control system and convert them into mechanical actions to control the travel of the movable base. However, this control method is a one-to-one structure, with one electric actuator controlling one movable base. If the electric actuator malfunctions or loses power, the movable base cannot be controlled, ultimately affecting the safe and stable operation of the entire system. Summary of the Invention

[0004] The purpose of this invention is to provide an electric regulator for redundant adjustment of a magnetic wheel speed controller, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an electric regulator for redundant adjustment of a magnetic wheel speed regulator, specifically for adjusting the movable base of the magnetic wheel speed regulator, comprising a reducer and a control cabinet, wherein the reducer has an output end and two sets of input ends, and the two sets of input ends respectively form a transmission with the output end;

[0006] The unidirectional output end is connected to the drive shaft of the movable base, and the two sets of input ends are respectively connected to servo motors. The two sets of servo motors rotate synchronously and serve as hot backups for each other. When one set of servo motors fails or loses power, the other set of servo motors takes over the drive.

[0007] As a preferred technical solution, the control cabinet has a dual power supply automatic transfer switch. The control cabinet is connected to two power supplies. When one power supply fails, the dual power supply automatic transfer switch switches to the other power supply.

[0008] As a preferred technical solution, the control cabinet has two sets of PLC control modules. The two sets of PLC control modules synchronize data and control the two sets of servo motors. When one set of PLC control modules fails, the other set of PLC control modules continues to synchronize data and control the servo motors.

[0009] As a preferred technical solution, the reduction ratio of the reducer is greater than or equal to 60.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] This electric regulator has two sets of servo motors, two sets of PLC control modules, and two power supplies. With multiple redundancy settings, it has high reliability and will not affect the operation of the entire system due to the failure of one part. In case of servo motor failure, it can be replaced online to ensure that the system has a backup drive. Attached Figure Description

[0017] Example 1

[0018] The electric regulator is specifically used to regulate the movable base 20 of the magnetic wheel speed regulator 10. The electric regulator includes a reducer 40 and a control cabinet 30. The reducer 40 has an output end and two sets of input ends, and the two sets of input ends respectively form a transmission with the output end.

[0019] The unidirectional output end is connected to the drive shaft of the movable base 20, and the two sets of input ends are respectively connected to servo motor A41 and servo motor B42. Servo motor A41 and servo motor B42 rotate synchronously and serve as hot backups for each other. When one set of servo motor A41 fails or loses power, servo motor B42 takes over the drive.

[0020] Example 2

[0021] The electric regulator is specifically used to regulate the movable base 20 of the magnetic wheel speed regulator 10. The electric regulator includes a reducer 40 and a control cabinet 30. The reducer 40 has an output end and two sets of input ends, and the two sets of input ends respectively form a transmission with the output end.

[0022] The unidirectional output end is connected to the drive shaft of the movable base 20, and the two sets of input ends are respectively connected to servo motor A41 and servo motor B42. Servo motor A41 and servo motor B42 rotate synchronously and serve as hot backups for each other. When one set of servo motor A41 fails or loses power, servo motor B42 takes over the drive.

[0023] The control cabinet 30 has a dual power supply automatic transfer switch. The control cabinet 30 is connected to two power supplies. When one power supply fails, the dual power supply automatic transfer switch switches to the other power supply.

[0024] Example 3

[0025] The electric regulator is specifically used to regulate the movable base 20 of the magnetic wheel speed regulator 10. The electric regulator includes a reducer 40 and a control cabinet 30. The reducer 40 has an output end and two sets of input ends, and the two sets of input ends respectively form a transmission with the output end.

[0026] The unidirectional output end is connected to the drive shaft of the movable base 20, and the two sets of input ends are respectively connected to servo motor A41 and servo motor B42. Servo motor A41 and servo motor B42 rotate synchronously and serve as hot backups for each other. When one set of servo motor A41 fails or loses power, servo motor B42 takes over the drive.

[0027] The control cabinet 30 has a dual power supply automatic transfer switch. The control cabinet 30 is connected to two power supplies. When one power supply fails, the dual power supply automatic transfer switch switches to the other power supply.

[0028] The control cabinet 30 has two sets of PLC control modules. The two sets of PLC control modules synchronize data and control servo motors A41 and B42. If one set of PLC control modules fails, the other set of PLC control modules continues to synchronize data and control servo motors A41 and B42.

[0029] The reduction ratio of the reducer 40 is greater than or equal to 60, thereby preventing the electric regulator from reversing under external force.

[0030] Specifically, the magnetic wheel speed regulator 10 drives the conductor wheel 11 to rotate via a motor. The strong magnetic field generated by the permanent magnet wheel 12 passes through the air gap and induces eddy currents in the conductor wheel 11. These eddy currents generate an opposite magnetic field, which interacts with the permanent magnet magnetic field, thereby driving the permanent magnet wheel 12 to rotate and transmitting torque to the load. During operation, the electric regulator adjusts the movement of the moving base 20 of the magnetic wheel speed regulator 10. The moving base 20 drives the motor to move axially, changing the coupling area between the conductor wheel 11 and the permanent magnet wheel, thereby adjusting the transmitted torque and changing the speed of the load. The electric regulator has two sets of servo motors, two sets of PLC control modules, and two power supplies, with multiple redundant settings, ensuring high reliability. The failure of one component will not affect the operation of the entire system. If one set of servo motors fails, it can be replaced online, ensuring that the system has a backup drive.

[0031] Two sets of servo motors are connected to the two input ends of the worm gear of the reducer 40. When replacing the servo motor, the servo motor is kept in a stable position. The power and control lines of the servo motor use quick-connect connectors for direct plugging and unplugging for replacement.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
