Hybrid excitation doubly salient permanent magnet synchronous motor

Abstract

The invention discloses a hybrid excitation doubly salient permanent magnet synchronous motor. The motor comprises a left shell; and opening and closing assemblies are arranged on the upper side and the lower side of a connecting plate. According to the hybrid excitation doubly salient permanent magnet synchronous motor, one-way locking can be realized when an inserting rod is inserted into a right side connecting plate through clearance fit between the inserting rod and the right side connecting plate and one-way clamping connection between a clamping pin and a clamping groove under the action of a first spring, so that a shell of the motor is quickly disassembled and assembled, and the interior of the motor is conveniently overhauled and maintained; a motor rotating shaft and an external connecting shaft are rapidly connected, and the connecting convenience is improved; the external connecting shaft can be automatically centered while fixing is conducted, so that transmission of the motor rotating shaft and the external connecting shaft is more accurate; the motor can axially rotate with a stand column as the axis after being fixedly installed, and is fixed through clamping connection of a clamping rod and a gear, and therefore, convenience and applicability of installation and use of the motor are improved, and the motor can be applied to more use environments.

Description

technical field [0001] The invention relates to the technical field of a hybrid excitation double salient pole permanent magnet synchronous motor, in particular to a hybrid excitation double salient pole permanent magnet synchronous motor. Background technique [0002] Since the electric excitation synchronous motor can easily adjust the DC excitation, and the DC excitation capacity for adjusting the magnetic field is small, it has advantages that the permanent magnet motor cannot achieve in terms of magnetic field adjustment. The permanent magnet motor also has a series of unique advantages due to the cancellation of the brush and slip ring device, such as high efficiency, simple structure, small size, etc., but the air gap magnetic field of the PM motor is determined by the magnet steel and the magnetic circuit permeability. , remains almost constant during operation and is difficult to adjust, which largely limits the development and application of PM motors. There are t...
