Car 1 is held stationary in proportion to the braking force in the downward direction. The maximum braking force of the electromagnetic brake 6 in the descending direction is maximum when the car 1 is empty. Conversely, when the loading weight of the car 1 is 50% or more (point M), a downward force acts on the car 1, and the downward force balances the braking force of the electromagnetic brake 6 in the upward direction.

Let it. If the failure of the electromagnetic brake 6 is determined not only by the rotation of the encoder 7 but also by the output of the car position sensor 11, the accuracy of the determination can be increased.
- the electromagnetic brake 6 can hold the car 1 stationary only by generating a braking force corresponding to the difference between the straight line I and these ⁇ , ffl, IV lines. If the reduction of the braking force due to the failure of the electromagnetic brake 6 'is equal to or less than the braking force generated by the electric motor torque control of the first embodiment, the movement of the car 1 can be prevented.
- Various methods can be used to determine the value of the torque generated by the motor torque control. When the encoder 7 detects minute rotation of the electric motor 5, it is possible to determine whether the braking force in the upward or downward direction from the rotation direction is insufficient.
- the value of the unbalanced load can be obtained, so that the direction and magnitude of the braking force necessary to hold the car 1 stationary can be considerably accurate.
- the torque value applied to the motor 5 to prevent the rotation of the motor 5 is based on the value of the unbalanced load measured using the balance 10 as shown by the straight line ⁇ in Fig.
- the braking force is generated by the electric motor 5.
- the load is in the dead zone between points A and B, as indicated by the polygonal line m, no braking force is generated, and the braking force is generated in other areas according to the unbalanced load.
- point C a constant braking force for each of positive and negative values in a region other than the dead zone, such as a broken line IV, by the motor 5.
- FIG. 6 is a diagram showing the relationship between the braking force generated by the electromagnetic brake and the loaded weight of the car.
- the limiting means 9 of the control device 9 so that the braking force to be generated does not exceed the point P or the point Q as shown in FIG. 6 so that the motor 5 is not overloaded. According to 06, restrictions may be added.
- the car 16 is controlled by the alarm 16 from the car 1 under the control of the notification controller 910 of the control device 9. May be notified to the passengers early exit.
- the elevator control system stops at the platform where the car is located, opens the car door for passengers to get on and off, and operates the electromagnetic brake while the electromagnetic brake is operating.
- the controller controls the electric motor so as to generate a torque for preventing the rotation of the electric motor when the car starts to move slightly and the encoder detects the rotation angle of the electric motor due to insufficient stationary holding force of the electromagnetic brake due to a failure. Since the drive control is performed, even if the electromagnetic brake causes a problem of insufficient braking force, the braking force is increased by the electric motor, and an elevator control system that does not pose a danger to passengers can be obtained. .
