Abstract:
A brake (3) for a motor comprises: a fixed-side engaging plate (30) fixed to a motor shaft (4); a movable-side engaging plate (20) coaxially opposed to the fixed-side engaging plate (30) along the direction of a center axis (3a); and a self-holding type solenoid (10) that moves, in the direction of the center axis, the movable-side engaging plate (20) to a halt cancelation position (20A) separated from the fixed-side engaging plate (30) and a halt position (20B) where engagement with the fixed-side engaging plate (30) occurs. When the motor is halted, the solenoid (10) is driven to move the movable-side engaging plate (20) from the halt cancelation position (20A) to the halt position (20B). The movable-side engaging plate (20) which has reached the halt position (20B) is mechanically engaged with the fixed-side engaging plate (30), and the motor shaft (4) is forcibly halted.
