Description

Technical Field

[0001] This utility model discloses an 86-type stepper motor structure for direct drive of gate machines, belonging to the field of stepper motors. Background Technology

[0002] Currently, conventional valve control systems on the market use separate structures for motor control and manual control. Conventional stepper motors, after installing a gearbox, still require a handwheel control mechanism within the device. This places high demands on the internal space of the control system, typically requiring two independent control systems, resulting in high cost, complex structure, and difficult maintenance. This approach is unsuitable for users with limited installation space and strict cost requirements. Utility Model Content

[0003] The main purpose of this utility model is to reduce the waste of product space, while allowing direct drive by handwheel, saving non-renewable resources, and reducing system maintenance costs through direct handwheel mounting.

[0004] To address the aforementioned issues, this invention incorporates an embedded cavity in the front cover of the 86 motor, a hollow rotating shaft, and a transmission sleeve on the rear output shaft. The embedded cavity houses the gear structure to amplify the motor torque, while the hollow rotating shaft facilitates cable connection for signal transmission at both ends. The transmission sleeve allows for the direct mounting of a handwheel, enabling the handwheel to drive the motor and control the gate in case of power system malfunction.

[0005] The technical solution of this utility model is as follows: A type 86 stepper motor structure for direct drive of turnstiles includes a motor body, a front cover, a rear cover, and a rotating shaft. The front end cover is provided with an inwardly recessed gear cavity, the depth of which is not less than the thickness of the gear set. The rotating shaft is an axially continuous hollow structure, forming a cable channel; The rear end extension of the rotating shaft is fitted with a transmission sleeve, and the outer end face of the transmission sleeve is provided with a handwheel mounting interface for mounting the handwheel disc.

[0006] Preferably, the gear cavity is used to embed a planetary gear set, wherein the sun gear of the planetary gear set is fixed to the front end of the rotating shaft, and the gear ring is fixed to the inner wall of the cavity.

[0007] Preferably, the transmission sleeve and the rotating shaft transmit torque through a keyway or spline.

[0008] Preferably, the motor power line and encoder signal line are run through the cable channel of the hollow shaft, and the two ends are respectively connected to the motor stator winding and the external controller.

[0009] The beneficial effects of this utility model are: The structural design of this utility model reduces installation space, simplifies control methods, facilitates maintenance, and saves resources. When the installation space for the turnstile is limited, a simpler installation structure facilitates later system maintenance, greatly reducing maintenance costs for users.
