[0003] Chinese patent publication number CN217508479U discloses a non-contact brake motor. When a permanent magnet fixed on the motor shaft rotates with the rotor, a hysteresis plate fixed on the motor housing generates a magnetic field to hinder the rotation of the permanent magnet.

[0004] The distance between the permanent magnet and the hysteresis band of the brake motor in the above technology remains unchanged. When the rotor rotates, it will be disturbed by the hysteresis band and needs to overcome the magnetic force of the hysteresis band before it can rotate, which leads to higher energy consumption.

[0012] As a further solution of the present invention, limit bearings matching the motor shaft are provided on both sides of the motor housing and at positions corresponding to the motor shaft.

[0013] Compared with the prior art, the anti-interference brake motor of the utility model has the following beneficial effects:

[0014] When the motor is turned on, the power supply of the electromagnetic coil is turned on, the electromagnetic coil generates magnetism and attracts the iron sheet, thereby driving the hysteresis plate to move in the direction away from the permanent magnet, increasing the distance between the hysteresis plate and the permanent magnet, reducing the obstruction of the hysteresis plate to the permanent magnet, avoiding interference from the hysteresis band during rotation, and reducing the consumption of the motor rotor rotation.

For example, it can be a fixed connection, an integral connection, or a detachable connection; it can be the internal connection of two components; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0028] See attached Figure 1-4 As shown, an embodiment of the utility model is an anti-interference brake motor, including a motor housing 1, a motor stator 101 is arranged on the inner wall of the motor housing 1, a motor rotor 102 matching the motor stator 101 is installed inside the motor housing 1 and at a position corresponding to the motor stator 101, and a brake mechanism 103 for braking is also installed inside the motor housing 1 and at a position corresponding to the motor rotor 102.

[0029] See attached Figure 3 As shown, the motor rotor 102 includes a motor shaft 1021 rotatably mounted on the motor housing 1 , a rotor coil 1022 matching the motor stator 101 is arranged on the motor shaft 1021 and at a position corresponding to the motor stator 101 , and a permanent magnet 1023 is also fixedly connected to the motor shaft 1021 .

[0030] See attached Figure 4 As shown, the brake mechanism 103 includes a mounting plate 1031 fixedly connected to the inner wall side of the motor housing 1, telescopic components 1032 are provided at the top and bottom of the side of the mounting plate 1031, the two telescopic components 1032 are connected by a hysteresis plate 1033, an iron sheet 1034 is provided on the side of the hysteresis plate 1033, and an electromagnetic coil 1035 is installed on the side of the mounting plate 1031 and at the position corresponding to the iron sheet 1034.

[0031] The telescopic assembly 1032 includes a mounting slide rod 10321 fixedly connected to the side of the mounting plate 1031, and a mounting sleeve 10322 is slidably connected to the mounting slide rod 10321. The side of the mounting sleeve 10322 close to the hysteresis plate 1033 is fixedly connected to the hysteresis plate 1033, and a sleeve spring 10323 is sleeved on the mounting slide rod 10321 located between the mounting sleeve 10322 and the mounting plate 1031.

[0032] The anti-interference brake motor using the above technical solution can reduce the obstruction of the hysteresis plate 1033 to the permanent magnet 1023 when the motor rotates, thereby reducing the consumption of the motor rotor 102 rotation. When the motor stops, the power supply of the electromagnetic coil 1035 is disconnected at the same time. Therefore, under the elastic force of the sleeve spring 10323, the hysteresis plate 1033 is driven close to the permanent magnet 1023, thereby increasing the obstruction of the hysteresis plate 1033 to the permanent magnet 1023, thereby achieving a good braking effect.

[0035] When the motor is turned on, the power supply of the electromagnetic coil 1035 is turned on, the electromagnetic coil 1035 generates magnetism and attracts the iron sheet 1034, thereby driving the hysteresis plate 1033 to move in the direction away from the permanent magnet 1023, increasing the distance between the hysteresis plate 1033 and the permanent magnet 1023, reducing the obstruction of the hysteresis plate 1033 to the permanent magnet 1023, thereby avoiding interference from the hysteresis plate 1033 during rotation, reducing the consumption of the motor rotor 102, and disconnecting the power supply of the electromagnetic coil 1035 when the motor is disconnected. Therefore, under the elastic force of the sleeve spring 10323, the hysteresis plate 1033 is driven close to the permanent magnet 1023, increasing the obstruction of the hysteresis plate 1033 to the permanent magnet 1023, thereby achieving a good braking effect.
