The invention provides an integral direct drive device of a gantry crane, relating to a drive device in which a permanent magnet direct drive motor and a signal detector are manufactured into a whole. A radial radiating fin is arranged outside a shell; the shell is provided with a spindle; the spindle in the shell is connected with a permanent magnet direct drive motor rotor; a permanent magnet direct drive motor stator matched with the permanent magnet direct drive motor rotor is fixed in the shell; the spindle in the shell is connected with a signal detector rotor; and a signal detector stator matched with the signal detector rotor is fixed in the shell. The integral direct drive device is concise and compact, improves the drive control accuracy, strengthens the integral protection grade of products, simplifies the system structure of the gantry crane, saves the space, and is convenient to install, debug and maintain; in addition, by using the integral direct drive device, the system structure of the gantry crane can be effectively simplified, the system space is saved, the installation and debugging are more convenient and faster, and the cost of an elevator gantry crane system is reduced.
Description
technical field [0001] The invention relates to an integrated door machine direct drive device, in particular to a drive device in which a permanent magnet direct drive motor and a signal detector are integrally manufactured. Background technique [0002] Simplicity and compactness are the development trend of the elevator door operator system. At present, the door machine driving device with asynchronous induction motor and encoder has complicated structure, occupies space, and is difficult to install, debug and maintain. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the old driving device and provide an integrated elevator door machine direct drive device with simple structure and convenient installation and maintenance. [0004] In the present invention, radial heat sinks are arranged outside the casing, and a rotating shaft is arranged on the casing. The rotor of the permanent magnet direct drive motor is c...
