Abstract:
An elevator speed governor for an elevator in which an elevator car (1) is attached to one end of a rope (2) having a counterweight (3) on the other end and driven by a motor (5) via the rope (2) comprises a motor current detector (15) that detects a motor current of the motor (5), a target speed determining section (11) that determines a target speed in accordance with the motor current detected by the motor current detector (15), and a motor control section (13) that controls the motor (5) so that the elevator car (1) moves at the target speed determined by the target speed determining section (11).
