Embodiment Construction

[0027] The invention will be described in further detail below in conjunction with the accompanying drawings.

[0028] figure 1 It is a longitudinal sectional view of a two-phase electric excitation doubly salient pole electric sunroof drive motor of the present invention. A two-phase electric excitation doubly salient pole electric sunroof driving motor is composed of a stator core (1), a mover (2), an excitation isolation block (3), an excitation winding (4), a guide rail (7) and an armature winding.

[0029] The stator core (1) is in the shape of a long strip. Let the length direction of the strip be the x-axis, the thickness direction of the top and bottom of the strip is the y-axis, and the width direction of the strip is the z-axis. There is a column on the stator core (1) facing the y-axis Stator poles protruding in the direction, the stator poles are parallel to the z-axis and arranged in sequence along the x-axis, and the pole distance between adjacent stator poles i...

Abstract

A two-phase electric excitation doubly salient pole electric sunroof driving motor is characterized in that it consists of a stator core (1), a mover (2), an excitation isolation block (3), an excitation winding (4), a guide rail (7) and an armature winding composition; the stator core (1) has a row of stator poles protruding in the direction of the y-axis; the elongated mover is located above the stator core (1), and the mover (2) has a row of protruding poles in the direction of the negative y-axis There is a field winding (4) between every two stator poles, the field winding (4) is wound around the x-axis direction where the length of the stator core (1) is located, and the adjacent field winding (4) is wound In the opposite direction; the armature winding is wound around the stator pole, and the A-phase armature winding and the B-phase armature winding are arranged at intervals; the mover (2) is connected to the sunroof, and the stator core (1) is connected to the vehicle body, when the mover ( 2) The sunroof can be opened or closed while moving. The technology of the present application does not have a worm gear reduction mechanism, and is light in weight, thin in thickness and high in transmission efficiency.

Description

technical field [0001] The invention relates to a two-phase electric excitation double salient pole electric sunroof driving motor, which belongs to the technical field of automobile electric appliances. Background technique [0002] The electric sunroof is driven by a motor, and the sunroof will automatically open or close when the switch button is pressed. Compared with the traditional old-fashioned sunroof, the electric sunroof is much more convenient to operate. Therefore, many car manufacturers will equip their cars with electric windows to attract more consumers. [0003] The traditional electric sunroof drive motors are all rotating motors, which must be equipped with a worm gear reduction mechanism before they can be used. It is difficult for electric sunroofs with these transmission mechanisms to reduce the thickness of the car roof. [0004] Linear motor technology offers a great solution for electric sunroofs. If a linear motor is used to drive the electric sun...
