Abstract

The invention discloses a winch roller device directly driven by frameless combined type permanent magnet synchronous linear motors. The winch roller device directly driven by the frameless combined type permanent magnet synchronous linear motors comprises a base. A fixed shaft is arranged on the base and fixed through a shaft pressing cover. The fixed shaft is sleeved with a first roller and a second roller. A fourth bearing is arranged between the first roller and the second roller. The part, at the tail end of the first roller, of the fixed shaft is provided with one synchronous linear motor. The part, at the tail end of the second roller, of the fixed shaft is provided with the other synchronous linear motor. Each synchronous linear motor comprises a stator assembly and a rotor assembly, wherein the stator assembly is composed of a plurality of stator units of fan-shaped structures, each stator unit is an independent controlling mechanism and comprises a stator iron core and a stator winding wound around the stator iron core, the stator assembly is fixedly installed on the fixed shaft, and the rotor assembly is fixedly connected with the inner walls of the tail ends of the first roller and the second roller. The two rollers are installed on the fixed shaft integrally, the space is saved, and meanwhile energy loss is lowered.

Description

technical field [0001] The invention belongs to the field of hoisting machines, in particular to a hoisting machine drum device directly driven by a frameless combined permanent magnet synchronous linear motor, which is suitable for hoisting winches, winches, hoisting machines and other equipment. Background technique [0002] Existing winch mainly is made up of power system, transmission system, work system, control indication system etc. and its subsidiary parts. It uses the driving motor as the power source, and through the gear box, the main shaft device and other transmission systems and working systems, the steel wire rope wound on the drum in the main shaft device is retracted and retracted, so as to realize the work of winches, hoists and other equipment. The traditional hoist needs to be equipped with a gearbox, which has relatively low efficiency, is prone to failure, has poor reliability, requires frequent maintenance, and occupies a large space; AC asynchronous m...
