Wiring device of mining explosion-proof permanent magnet synchronous variable-frequency traction motor

Abstract

The invention discloses a wiring device of a mining explosion-proof permanent magnet synchronous variable-frequency traction motor. The wiring device comprises a base, a stator winding, a wiring boltand an insulating sleeve, wherein the stator winding is installed in the cylinder wall of the base in a winding manner, and a preset distance is formed between the stator and one opening of the base;a first through hole penetrating through the cylinder wall is formed in the preset distance, the insulating sleeve is fixed outside the cylinder wall of the base through the first through hole, and the bottom end of the insulating sleeve extends into the cylinder wall; and a wiring bolt penetrates into and is fixed in the insulating sleeve, and the upper end and the lower end of the wiring bolt are respectively exposed out of the top end and the bottom end of the insulating sleeve. According to the invention, the problem that the space of a motor junction box is compressed is solved; the mining explosion-proof permanent-magnet synchronous variable-frequency traction motor solves the problem that a mining explosion-proof permanent-magnet synchronous variable-frequency traction motor in an improved transport locomotive head for a coal mine cannot be designed due to the fact that a terminal sleeve cannot be arranged, a special stop gasket, a terminal electrical gap and a creepage distancecannot meet standard requirements, simplifies the device and reduces the cost at the same time.

Description

technical field [0001] The invention belongs to the technical field of electric motors, and in particular relates to a mining explosion-proof permanent magnet synchronous frequency conversion traction motor wiring device installed in the front of an improved coal mine transport locomotive.
