The invention discloses an electromagnetic device for an elevator brake, the elevator brake and an elevator system. At least two electromagnetic devices are arranged in the elevator brake, and each electromagnetic device comprises a fixing part which is fixed relative to an elevator power device and is provided with at least one electromagnetic part used for providing electromagnetic force after being electrified; the moving part is arranged between the fixed part and a friction part of the elevator brake and can move relative to the fixed part; the force supply part is arranged to be used for providing acting force opposite to the direction of the electromagnetic force for the moving part, so that when the elevator brake is in the first state, the moving part is driven by the acting force to move towards the friction part and makes contact with an elevator power device to provide braking force, and an elevator car is stopped; and when the elevator brake is in the second state, the electromagnetic force is provided to overcome the acting force to promote the moving part to move towards the fixed part, so that the friction part is separated from the elevator power device.

    本发明公开了用于电梯制动器的电磁装置、电梯制动器和电梯系统。所述电磁装置被构造成用于在电梯制动器中至少设置两个,其中每一个电磁装置包括:固定件,其相对于电梯动力装置固定,并设置有至少一个电磁件用于在通电后提供电磁力;运动件,其布置在固定件和电梯制动器的摩擦件之间,并设置成能相对于固定件运动;供力件,其设置成用于向运动件提供与电磁力方向相反的作用力,以使得在电梯制动器处于第一状态下时,运动件被该作用力驱使朝向摩擦件运动并使其与电梯动力装置接触来提供制动力而使得电梯轿厢止停,在电梯制动器处于第二状态下时,电磁力被提供用来克服该作用力以促使运动件朝向固定件运动,从而使得摩擦件与电梯动力装置脱离接触。
