Explosion-proof half-direct driven permanent magnet motor

Abstract

The invention discloses an explosion-proof half-direct driven permanent magnet motor which is formed by combining a loading type reduction gear (1) and an external permanent magnet motor. The permanent magnet motor is composed of a rotor (5), a stator (4), an explosion-proof connecting box (2) and an explosion-proof engine base, wherein the stator (4) is provided with an armature winding and is arranged in the explosion-proof engine base with the explosion-proof connecting box (2); the input shaft of the loading type reduction gear (1) is assembled with the rotor (5) through a bolt (7); magnetic steel is attached on the outer surface of the rotor (5); the loading type reduction gear (1) is fixedly connected with the front end of the engine base (3) by screw bolts through a front end cover; the back-end input shaft of the loading type reduction gear (1) is loaded in a back end cover with a bearing (10); the back end cover (6) and the engine base (3) are fixedly connected through the screw bolts; and the bearing (10) is provided with a bearing cover (8) and a double-lip encapsulated skeleton oil seal (9). The explosion-proof half-direct driven permanent magnet motor has the advantages of high efficiency, low noise, large torsion, strong overload capacity, stable operation, small volume, light weight and the like.

Description

technical field [0001] The invention belongs to a kind of electromechanical equipment for mining, in particular to an explosion-proof semi-direct drive permanent magnet motor. Background technique [0002] At present, there are two main types of mining traction technology: one is DC motor; the other is asynchronous motor. [0003] Although the DC motor has the advantages of high efficiency and good speed regulation performance. However, traditional DC motors use brushes and commutators to commutate in the form of mechanical structures, which inevitably have disadvantages such as large mechanical noise, large spark interference, short service life, etc., and high manufacturing costs; difficult maintenance, which limits its scope of use. [0004] Although the asynchronous motor has the advantages of simple structure, good reliability, low manufacturing cost, and convenient maintenance, it also has disadvantages such as poor speed regulation performance, low overload capacity...
