With the recent rise in land prices, residential land has become increasingly narrow and difficult to obtain. As a result, houses have increased in height from two to three stories, and there is a trend for two generations to live together. In such houses, common areas such as kitchens and private rooms such as bedrooms are located on different floors, and inter-floor communication is essential. This makes it difficult for elderly households to live there, and it also becomes troublesome to carry luggage into and out of the third floor. Therefore, it has been proposed to install elevators in such private residences, and there is a demand for small and simple elevators.

By the way, in the above-mentioned elevator drive device, the hoisting machine 4 is disposed above the car 1 to support the total weight of the car 1 and the counterweight 2, so the building supports the total weight and the hoisting machine 4. The weight of the upper machine and the electric motor must also be supported, making the pillars thicker and the building more expensive.

In addition, since the three-phase AC power supplies R, S, and T are connected to the motor 5 with the phase order switched between the ascending direction operation and the descending direction operation, the ascending direction contactors 11a and 1 are connected to the electric motor 5, respectively.
1b and downward direction contactors 12a, 12b are required, which has the disadvantage of complicating control.

As described above, the present invention provides an elevator drive device for raising and lowering a car by driving, with an electric motor, a hoist that generates a load torque in the direction of winding and constantly rewinding one end of the main rope that suspends the car. Upward operation is performed by supplying three-phase AC power to the motor to generate drive torque and winding up the main rope against the load torque, and downward operation is performed by disconnecting the control rectifier connected to the three-phase AC power. This is done by applying the single-phase AC power obtained by making it conductive to the motor, and rewinding the main rope in conjunction with the above load torque, and as necessary when approaching the destination floor during both ascending and descending operations. The motor is designed to apply direct current to the electric motor to generate braking torque.

1. A main rope that suspends the car, a hoist that winds and unwinds one end of the main rope to raise and lower the car, an electric motor that drives the hoist, and a motor that rotates the electric motor in the direction that raises the car. phase AC power supply,
a control rectifier connected to the three-phase AC power supply to change the AC voltage; a rectifier circuit that rectifies the AC supplied from the AC power supply and outputs DC to generate braking torque for the motor; The three-phase alternating current and the direct current are selectively supplied to operate the cage upwardly, and the control rectifying element is made non-conductive without changing the phase order of the alternating current power source, thereby cutting out one phase. An elevator drive device comprising a control means for driving the car downward by selectively supplying a single-phase alternating current obtained from a power source and the direct current.
