Description:
ELECTROMAGNETIC ELEVATOR MOTOR BRAKE

TECHNICAL AREA

The invention is related to the improvements made on the electromagnetic elevator motor brake in such a way as to ensure safer and longer-lasting operation of the electromagnetic motor brake, which is used especially in elevator drive motors.

PRIOR ART

Especially the gearless system used in elevator systems, electromagnetic braking systems are used extensively today for the braking of gearless elevator drive motors. The brake system on the elevator drive motor consists of the coil body, which contains the coils that create a magnetic field, and the axial rotor, which is positioned between the body and the brake disc and brake pad. During the operation of the elevator drive motor, the axial rotor is pulled towards the coil body by the electromagnetic effect created by the electric current passing through the coils in the brake system, and the brake disc with the pad is discharged and the brake is released. By stopping the drive motor, the current passing through the coils is interrupted and the electromagnetic attraction on the axial rotor is eliminated. Thus, braking occurs when the springs between the coil body and the axial rotor are released and the axial rotor moves the lining on the motor.

In the current technique of the elevator motor brakes used, the electromagnetic effect is obtained through the coil windings, while the coil windings are carried out on circular bodies. When the previous GB2236623A and WO2006136246A1 documents are examined, it was understood that electromagnetic fields with single or multiple coil bodies are tried to be created. As can be seen in the documents, coil winding surfaces generally contain circular continuous-form surfaces, the bodies in which the coils are placed are selected to have circular or angular continuous edges. The generated magnetic brake of the elevator drive motor is one of the most important factors in a healthy and highly effective way given that the domain of a magnetic field coil winding and coil placement can be created in sections so that changes in the structure of the body are of high importance.

BRIEF DESCRIPTION OF THE INVENTION

The electromagnetic elevator motor brake, the subject of the invention, has been developed to obtain the braking to be obtained in elevator drive motors more safely and to extend the material life.

The coil body (1 ) in the developed electromagnetic elevator motor brake is manufactured with a forged steel production technique. On the coil body (1 ), a tightening zone (1.1 , 5.1 ) is created during forging manufacturing, resulting in a more dense and high-strength material with a lower quantity of raw materials, while the electromagnetic insulation property of the material is increased. The coil body is alternatively selected according to the dimensions of the elevator motor and brake disc and manufactured as a two-piece coil body (1 ) or a one-piece coil body (5) for use.

Cooling channels (1.2.1 , 5.2.1 ) are created in the coil core (1.2, 5.2) sections of the developed electromagnetic elevator motor brake, thereby reducing the heating effect that will occur with the electromagnetic effect on the coil body (1 ), while increasing the magnetic effect to be achieved.

Cooling channels (1.4.1 , 5.4.1 ) are created in the outer bowl of the coil (1 .4, 5.4) sections of the developed electromagnetic elevator motor brake, thereby reducing the heating effect that will occur with the electromagnetic effect on the coil body (1 ), while increasing the magnetic effect that will be achieved.

The axial rotor (2) in the developed electromagnetic elevator motor brake is manufactured with a forged steel production technique. On the axial rotor (2), a tightening zone (2.1 ) is created during forging manufacturing, resulting in a more dense and high-strength material with a lower quantity of raw materials, while the electromagnetic insulation property of the material is increased.

The subject of the invention is the part manufactured by the forging steel manufacturing technique to contain at least one tightening zone (1.1 , 5.1 ) on the coil body (1 , 5) located in the electromagnetic elevator motor brake.

The subject of the invention consists of a tightening zone (1 .1 , 5.1 ) formed on the coil body (1 , 5) located in the electromagnetic elevator motor brake in such a way that it forms a recess from the outer edge of the body (1 , 5) to the center of the body (1 , 5).

The subject of the invention is the coil body (1 , 5) in the electromagnetic elevator motor brake, which is manufactured as a two-piece coil body (1 ) or a one-piece coil body (5) that can be used alone on the elevator motor by symmetrically positioning the same two parts created in the same way to be selected according to the size of the elevator motor and brake disc. A two-piece coil body (1 ) or one-piece coil body (5) is selected depending on the disc size to be used on the elevator motor and the desired braking power mounted on the elevator motor. The coil winding sections located on both coil bodies (1 , 5) are used with the same technical specifications.

The invention of the electromagnetic motor brake coil elevator developed in the core (1.2, 5.2), the coil core (1.2, 5.2) contains at least one core cooling channel (1.2.1 , 5.2.1 ) formed in such a way that it forms a recess along its perimeter and towards the center of the coil core (1 .2, 5.2). The subject of the invention the coil core (1.2, 5.2) developed in the electromagnetic elevator motor brake preferably contains at least one core cooling channel (1.2.1 , 5.2.1 ) formed along the entire height of the coil core (1 .2, 5.2).

The subject of the invention the coil outer bowl (1 .4, 5.4) developed in the electromagnetic elevator motor brake, and the coil outer bowl (1.4, 5.4) includes at least one bowl cooling channel (1.4.1 , 5.4.1 ) formed along the edge circumference and indented inwardly from the edge of the coil outer bowl (1 .4, 5.4).

The coil outer bowl (1.4, 5.4) developed in the subject of the invention of electromagnetic elevator motor brake preferably contains at least one bowl cooling channel (1.4.1 , 5.4.1 ) formed along the entire height of the coil outer bowl (1.4, 5.4).

The subject of the invention is the axial rotor (2) developed in the electromagnetic elevator motor brake, which is a part manufactured by the forging steel manufacturing technique to contain at least one tightening zone (2.1 ) on it.

The subject of the invention the axial rotor (2) developed in the electromagnetic elevator motor brake contains a tightening zone (2.1 ) formed on it in such a way as to create an indentation from the outer edge of the rotor (2) towards the center of the rotor (2).

Because the coil body (1 , 5) in the electromagnetic elevator motor brake, which is the subject of the invention, is manufactured with the forged steel technique, the toughness and strength of the material are increased, while the magnetic insulation property of the material is also increased. In addition, thanks to the tightening zone (1.1 , 5.1 ) formed during steel forging on the body (1 , 5), the material is compressed and its strength and insulation properties are increased to higher levels. In this way, the influence of the electromagnetic field required for braking by external factors is reduced, and healthier and safer braking is achieved.

In the electromagnetic elevator motor brake, which is the subject of the invention, due to the fact that the axial rotor (2) is manufactured with the forged steel technique, the toughness and strength of the material are increased, while the magnetic insulation property of the material is also increased. In addition, thanks to the tightening zone (2.1 ) created during steel forging on the axial rotor (2), the material is compressed and its strength and insulation properties are increased to higher levels. In this way, the electromagnetic field required for braking is reduced to be affected by external factors, and healthier and safer braking is achieved.

In the electromagnetic elevator motor brake, which is the subject of the invention, the coil core (1.2, 5.2) and core cooling channel (1.2.1 , 5.2.1 ) formed in the coil outer bowl (1.4, 5.4), and thanks to the dish cooling channel (1.4.1 , 5.4.1 ), the transmission of the heat energy to the coil body (1 , 5), which will occur with the effect of the electric current passing over the coil windings, is minimized, and the material life of the body (1 .5) is extended.
