Abstract

The invention discloses an integrated hydraulically-driven permanent magnet synchronous generator which comprises a motor shell (25), a rotating shaft (24), a cylinder body (23), a permanent magnet (26) and a motor stator (27), wherein the right side of the cylinder body (23) is tightly attached to an oil distribution disk (20), and the left side of the cylinder body (23) is provided with an inclined disk (31); a plunger hole (32) is arranged in the cylinder body (23), a plunger (8) positioned in the plunger hole (32) is rotatably connected with a slide shoe (6), and the slide shoe (6) is tightly attached to the inclined disk (31); an oil inlet (15a) on an oil-pass joint block (16), an oil inlet passage in a right end cover (17) and an oil inlet window on the oil distribution disk (20) are communicated in sequence; and an oil outlet (15b) on the oil-pass joint block (16), an oil outlet passage in the right end cover (17) and an oil outlet window on the oil distribution disk (20) are communicated in sequence. The permanent magnet synchronous generator is used for converting hydraulic energy into electric energy.

Description

technical field [0001] The invention relates to hydraulic technology and a permanent magnet synchronous generator, in particular to an integrated conversion device from hydraulic energy to electric energy. Background technique [0002] Using a hydraulic motor to drive a generator to realize the conversion of hydraulic energy to electrical energy can be used in many occasions, such as potential energy recovery of hybrid construction machinery, field power supply, wind power generation, etc. Taking potential energy recovery of hybrid construction machinery as an example, hydraulic motors and generators are installed in the oil return circuit of the system. When the boom is lowered, the return oil back pressure formed by potential energy drives the generator to rotate through the hydraulic motor, and then uses capacitors or batteries to The energy storage device stores the electrical energy generated by the generator, thereby converting the hydraulic energy into electrical ener...
