a mechanism to reduce the 'peaks' of power in the startup of an electric motor asynchronous to the command type hydraulic elevator

摘要

a device is described that can reduce the "peak" of power in the startup of an electric motor asynchronous to the command type hydraulic elevators.the device in question consists of a core metal insert and isolated from a tubular body which is arranged a coil connected to the coil of the motor and refocusing on a pair of switches and / or teleruttori.said device may be immersed in the same fluid operating of the engine, is likely to cause a reduction of the initial current during the startup of the aforementioned engine.
