[0008] In the conventional hanging type elevator system,

However, in the self-propelled elevator system, it is necessary to obtain the entire propulsion force for moving the car by a linear motor, etc., and for this purpose, it is necessary to operate the car of the same weight using a hanging type elevator system. When compared with the case where the elevator is operated by a self-propelled elevator system, the self-propelled elevator system requires significantly more capacity. Furthermore, in self-propelled elevators, it is necessary to install a linear motor etc. in the car, and even if the car has the same loading weight, the weight of the car itself is greater in self-propelled elevators than in suspension-type elevators. It also becomes heavier due to the weight of the linear motor.

[0010] Therefore, although the self-propelled elevator system has superior transportation capacity, it requires a much larger electric motor capacity to operate a car with the same loaded weight. For this reason, it is necessary to increase the capacity of the inverter and power supply that drive the electric motor, and there is a problem in that the capacity of the entire system is significantly larger than that of the conventional crane elevator system.

[0012] In this respect, in the conventional door driving device for a sliding elevator, as shown in FIG. The drive electric motor 7 is configured to open and close via a speed reducer 8 and a door link 9. If such a conventional door drive device is applied as a door drive device for a self-propelled elevator, the weight of the car can be reduced by the traveling car. The electric motor for opening and closing the door is also loaded together with the linear motor for the door, which becomes a major impediment to weight reduction.
