Embodiment 1

[0024] like Figure 1-4 As shown, the built-in door motor of this controller includes a motor casing 1 with a chamber, and a stator 2 with windings is arranged inside the motor casing 1, and an outer end is pierced in the stator 2 and extends to the motor casing The outside of the front end of the body 1 and the inner end are located at the rotating shaft 3 inside the motor housing 1. The rotor 4 is fixed on the rotating shaft 3. The stator 2 is in the shape of an annular disk. The machine housing 1 is provided with a controller circuit board 5 that is plate-shaped and equipped with electronic components and the motor housing 1 is used as a heat dissipation structure for the controller circuit board 5. The controller circuit board 5 is electrically connected to the winding of the stator 2, The controller circuit board 5 is laterally fixed in the motor housing 1 through the positioning structure 6 and is located between the inner end of the rotating shaft 3 and the rear end of ...

Embodiment 2

[0030] like Figure 5 As shown, the structure and principle of this embodiment are similar to the first embodiment, the difference is that the sealing structure 8 here includes a sealing groove 82 arranged circumferentially at the end of the extension housing 12, and the sealing groove 82 is set There is a sealing gasket 83 , and the cover plate 13 presses the sealing gasket 83 between the end of the extension housing 12 and the cover plate 13 .

Embodiment 3

[0032] The structure and principle of this embodiment are similar to the first embodiment, the difference is that the motor housing 1 here includes a first housing and a second housing, and the first housing and the second housing are respectively in the form of One end is closed and the other end is open, and the open ends of the first shell and the second shell are butted and fixed to each other, and a butt sealing structure is provided at the connection between the first shell and the second shell. An inner cavity 71 is located in the first housing, and the second inner cavity 72 is located in the second housing. The motor housing 1 here can be a split docking structure, and the first housing here can be an existing motor. The housing, that is, the existing motor housing is docked with the second housing to realize the motor housing, which saves costs.

Abstract

The invention relates to a door motor with a built-in controller. The door motor solves the problem that design in the prior art is not reasonable enough. The door motor comprises a motor shell, a stator is arranged inside the motor shell, a rotating shaft is arranged in the stator in a penetrating mode, a rotor is fixed on the rotating shaft, the stator is an annular disk body, and the stator is sleeved with the rotor; a plate-shaped controller circuit board is arranged inside the motor shell, the motor shell serves as a heat dissipation structure of the controller circuit board which is electrically connected with a winding of the stator, and the controller circuit board is transversely fixed inside the motor shell through a positioning structure and is located between the inner end of the rotating shaft and the rear end of the motor shell. The door motor with the built-in controller has the advantages that the structure is compact, the size is small, and an original controller shell and an original heat dissipation system are omitted; system cost is reduced; radiated interference of a control unit is reduced; an encoder is arranged inside and cannot be damaged during plugging and pulling in a using process by a user; the damage probability of the motor is reduced during installation and debugging.

Description

technical field [0001] The invention belongs to the technical field of elevator equipment and relates to a motor, in particular to a door motor with a built-in controller. Background technique [0002] The elevator door machine motor is a transmission device installed on the elevator door to control the opening and closing of the elevator door. Some motors have no control function themselves, and need the help of controllers and encoders to realize their operation. The development direction of door machine drive is to use permanent magnet synchronous motor, which is a servo drive motor, which has the advantages of good control characteristics and large starting torque. It can be used for elevator door machine drive to make elevator door switch flexible, fast and stable, and accurate positioning. The door-closing obstacle can be detected immediately through the current, which can make a qualitative change in the quality of the door operator. However, 80% of the existing ele...
