Abstract

A dynamic magnetic suspension device comprises a suspension magnet, a motor magnet, an upper shell and a lower shell, wherein the upper shell is connected with the lower shell through screws; the coils are uniformly distributed in the magnetic ring, the coils are internally provided with core rods, and the magnetic sensors are arranged at the end parts of the core rods; the circuit control board is connected with the motor circuit. The utility model discloses a developments magnetic suspension device through increasing intelligent control motor mechanism, keeps suspension magnet incessantly to rotate, and the suspended solid can do at the uniform velocity and rotate under the drive of motor, and its direction of rotation, speed can be controlled, switches at random at the arbitrary time, very big improvement suspended solid handicraft sight's visual effect.

Description

Dynamic magnetic suspension device

Technical Field

The utility model relates to a developments magnetic suspension device.

Background

Magnetic suspension device is various in kind on the existing market, and the function varies, mostly relies on manual pulling the suspended solid to rotate, under air resistance, the rotating object handicraft will stop soon, need continuously pull repeatedly, and pull the back, because of the power size difference rotational speed of using can't be even all the time, the very big sight that influences the suspended solid handicraft, the direction is single, can not the switching-over. For example, chinese patent 2006100653361, the direction and speed of rotation of the handicraft article are not adjustable, and under the air resistance, the rotation of the handicraft article gradually weakens and finally stops rotating.

Disclosure of Invention

The utility model aims at providing a dynamic magnetic suspension device with novel design, simple structure and free rotation.

The utility model discloses a dynamic magnetic suspension device, including suspension magnet, motor magnet, upper casing, lower casing, upper casing passes through the screw and links to each other with lower casing, its characterized in that, is equipped with motor, circuit control board, magnetic ring, coil in the inner chamber that upper casing and lower casing enclose, and the output shaft of motor sets up the plane symmetry center at the magnetic ring, and motor magnet and the output shaft of motor are connected; the coils are uniformly distributed in the magnetic ring, the coils are internally provided with core rods, and the magnetic sensors are arranged at the end parts of the core rods; the circuit control board is connected with the motor circuit.

The utility model discloses a developments magnetic suspension device, with chinese patent 2006100653361 is the same reason, through increasing intelligent control motor mechanism, keeps suspension magnet incessantly to rotate, has overcome the not enough of prior art, and the suspended solid can do at the uniform velocity and rotate under the drive of motor, and its direction of rotation, speed can be controlled, switch at random at the arbitrary time, very big improvement suspended solid handicraft sight's visual effect.

Detailed Description

A dynamic magnetic suspension device comprises a suspension magnet 1, a motor magnet 2, an upper shell 4 and a lower shell 5, wherein the upper shell 4 is connected with the lower shell 5 through screws, and the dynamic magnetic suspension device is characterized in that a motor 6, a circuit control board 7, a magnetic ring 8 and a coil 9 are arranged in an inner cavity defined by the upper shell 4 and the lower shell 5, an output shaft of the motor 6 is arranged at the plane symmetry center of the magnetic ring, and the motor magnet 2 is connected with the output shaft of the motor 6; the coils 9 are uniformly distributed in 8 circles of the magnetic ring, the core rod 3 is arranged in the coils 9, and the magnetic sensor 10 is arranged at the end part of the core rod 3; the circuit control board 7 is electrically connected with the motor 6.

The opposite polarities of the motor magnet 2 and the levitation magnet 1 are opposite, and the motor magnet 2 attracts the levitation magnet 1 to rotate together with the levitation magnet due to the principle that the opposite polarities attract each other. The upper surface of the annular magnetic ring 8 is opposite to the suspension magnet 1 in the same polarity, the suspension magnet 1 can float due to the principle that the same polarities repel each other, and the four coil groups which are symmetrical on the central shaft are respectively provided with a magnetic sensor 10 (Hall sensor) for controlling the exciting current of the coils, thereby controlling the free movement of the suspension magnet 1 in the direction of the central line. The low-speed rotation of motor 6 makes suspension magnet 1 obtain the rotation, and circuit control board 7 control motor 6 motion, and programmable transmission: and different commands of left turning, right turning, swinging and the like are used for enabling the levitation magnet 1 to complete the commands.

The motor 6 adopts 28BYJ-48, and the circuit control board 7 is provided with a program circuit chip U L N2803, a singlechip ST32 and a conventional control circuit.
