Problems solved by technology

[0004] However, with respect to the conventional electromagnetic brake as described above, if a voltage is applied to the brake shoe portion formed by the electromagnet, then the entire surface of the brake shoe portion and the entire surface of the brake disc portion are in close contact at the same time. A large frictional force is instantaneously generated between the brake shoe portion and the brake disc portion, so there is a problem that not only a large braking impact is applied to the rotating body during braking, but also the rotating body Instead of stopping slowly and softly, the body brakes sharply
[0005] Therefore, the above conventional conventional electromagnetic brake has the problem that it is practically impossible to apply it to an industrial robot arm that requires precise control or a surgical robot arm that requires more precise control.

Abstract

Disclosed is a magnetic brake for minimizing braking shock applied to a rotor by gradually increasing frictional force generated between a disk portion and a pad portion when braking the rotor and smoothly stopping the rotor. The magnetic brake has a very simple and compact structure thereby minimizing braking shock applied to the rotor and smoothly stopping the rotor, and thus can be made useful through an application to a joint portion of a robotic arm requiring precise control, is manufactured to have the simple and compact structure thereby minimizing limitations due to installation space, and can effectively render smaller and lighter various devices to which the magnetic brake is applied.

Description

technical field [0001] The present invention relates to an electromagnetic brake, and more specifically, to an electromagnetic brake capable of braking a rotating body. Background technique [0002] In general, as brakes for the purpose of dynamically braking the rotation of a rotating body, mechanical brakes and electromagnetic brakes are most widely used. The mechanical brake makes the brake shoe contact the rotating body with a mechanical structure, thereby Rotational motion is stopped by frictional force, and the electromagnetic brake utilizes magnetic force to bring a brake shoe into contact with a rotating body to stop rotational motion by frictional force. [0003] In the above-mentioned electromagnetic brake, when a voltage is applied to the brake shoe formed by the electromagnet, the brake disc provided in the rotating body moves toward the brake shoe, and the brake disc comes into close contact with the brake shoe. part, a frictional force is generated between the...
