Abstract
The present application provides a brake and a motor. The brake comprises a stator core (1), an armature (2), a friction plate (3) and a limit plate (4) arranged in sequence along the axial direction, the limit plate (4) and the stator core (1) are fixedly connected, a guide column (5) is arranged between the limit plate (4) and the stator core (1), the armature (2) can be limited by the guide column (5) and slide along the guide column (5), the armature (2) is a block structure, and adjacent blocks can be relatively displaced in the axial direction. According to the brake of the present application, the friction contact area can be increased to avoid the reduction of the static torque of the brake.
