Embodiment Construction

[0027] A single salient pole of a sector-shaped salient pole rotor of an electric motor, including a mandrel 5, a winding 11, a first group of salient pole rotor punches 1 and a second group of salient pole rotor punches 3, which are arranged at equal intervals on the mandrel 5 There are threaded through holes 6, a first mandrel through hole 2 is provided on the first group of salient pole rotor punches 1, and a second mandrel through hole with a notch is provided on the second group of salient pole rotor punches 3 4. On the mandrel 5, the first group of salient pole rotor punches 1 and the second group of salient pole rotor punches 3 are alternately pierced. The gaps provided on the second group of salient pole rotor punches 3 are the The threaded through-holes 6 provided at equidistant intervals on the 5 are correspondingly provided, and one end of the double-ended screw 10 passes through the gap provided on the second group of salient pole rotor punches 3 and is screwed to t...

Abstract

The invention discloses a single salient pole of a motor sector salient pole rotor and an assembly method of the single salient pole, and solves the technical problems of difficulty in wiring and poor overall ventilation cooling effects of an existing motor caused by a narrow reserved internal lead space of the existing motor. The single salient pole is characterized in that threaded through holes (6) are equidistantly arranged on a mandrel (5) at intervals, first mandrel through holes (2) are arranged on a first group of salient pole rotor sheets (1), second mandrel through holes (4) with notches are arranged on a second group of salient pole rotor sheets (3), the first group of salient pole rotor sheets (1) and the second group of salient pole rotor sheets (3) are alternately connected onto the mandrel (5) in a penetrating manner, the notches arranged on the second group of salient pole rotor sheets (3) correspond to the threaded through holes (6) equidistantly arranged on the mandrel (5) at intervals, and one end of a double-headed screw (10) is connected with the threaded through holes (6) arranged on the mandrel (5) in a threaded manner. The single salient pole is quite convenient to mount and machine.

Description

technical field [0001] The invention relates to a salient-pole rotor of a motor and an assembly method thereof, in particular to a salient-pole rotor of a motor made of laminated sector pieces and an assembly method thereof. Background technique [0002] Existing large-scale motor rotors are made of fan-shaped silicon steel sheets laminated to form a single magnetic pole. During the lamination process, the positioning and compression of each fan-shaped silicon steel sheet is completed by the mandrel and fixed plate at the center of the magnetic pole. The core at the center of the magnetic pole The shaft and the fixed plate ensure the concentricity and compactness of each fan-shaped silicon steel sheet, and at the same time, the process is simple and the installation is convenient. The way to solve these problems in the prior art is to use the connection of the dovetail groove, and finally use a long screw to install the entire magnetic pole on the shaft. The errors on the...
