Can do.
- a torque current command value that is, a torque command value may be used instead of the torque current.
- the voltage command calculator 33a has a storage unit that preliminarily stores data relating the torque command and the load amount, and calculates a torque command necessary to make the rotational speed follow the rotational speed command. The same effect as that of the above-described fourth embodiment can be obtained by estimating the load capacity of the car by taking out the load capacity corresponding to the torque command in the acceleration section of the elevator and taking out the memory capacity.
- Embodiments 1 to 4 have described the invention in which the operation curve of at least one of the operation curves of the sections D, E, and F is changed according to the load capacity of the car 11.
- the fifth embodiment a case will be described in which the operation is performed using the brake torque of the brake 16 in addition to the rotation machine torque of the rotation machine 20 in the sections D, E, and F.
- the configuration in the fifth embodiment is the same as that in FIG.
- FIG. 19 is a diagram showing an example of an operation curve of the elevator when the car 11 is raised in the fifth embodiment of the present invention.
- the horizontal axis indicates time
- the vertical axis indicates speed, acceleration, total output torque, rotating machine torque, and brake torque in order from the top.
- the rotating machine torque is a torque output from the rotating machine 20
- the brake torque is a braking torque output from the brake 16.
- Total output torque is the sum of rotating machine torque and brake torque.
- the rotating machine torque if the rotating machine 20 is controlled by the speed sensorless control means 30, a force S that can output both a running torque and a regenerative torque is obtained. Is not easy. Brake torque can be output by brake 16, but only regenerative torque can be output! /.
- Total output torque "Rotating machine torque” + "Brake torque” The relationship is established.
- the voltage command calculator 33a outputs a brake torque to the brake 16 before the elevator lift starts and after the lift is completed.
- the brake torque is applied in a specific section of the deceleration section.
- the voltage command computing unit 33a in the speed sensorless control means 30 controls the rotating machine 20 so that the rotating machine torque is reduced in the low speed-regenerative region in the sections D, E, and F.
- the brake torque of the brake 16 is compensated by the amount that the torque is kept small.
- the speed sensorless control means can reduce the low-speed regenerative torque by using the brake torque in combination according to the moving direction of the force and the load amount. In the section where the brake torque is applied, it is not necessary to change the operation curve according to the direction of movement of the force and the load capacity as shown in the embodiment 1-14. As a result, the speed sensorless control means can stably control the rotating machine and can suppress the delay in the elevator lift time.
- the acceleration operation curve itself preliminarily stored in the storage unit of the speed command signal generator is stored in the rotating machine in the low speed / regenerative region. It is possible to set an operation curve that reduces the torque.
- the present invention is not limited to this.
- the braking operation in the deceleration zone can be used in combination even when the acceleration operation curve corresponding to the moving direction of the car and the load amount of the car is used.
- the speed sensorless control means can stably control the rotating machine and can suppress the delay of the elevator rising and falling times.
- a general-purpose inverter for driving a rotating machine can apply a voltage to the rotating machine (induction machine) so that the desired rotating speed can be obtained by inputting a speed command.
- a general-purpose inverter can be used as the control means 30, a general-purpose inverter can be used.
