Embodiment Construction

[0028] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] The switched reluctance motor speed control drive system is the latest generation of stepless speed control system developed after the frequency conversion speed control induction motor and brushless DC motor speed control system. It is a combination of switched reluctance motor and power electronics technology. A mechatronic device.

[0030] The switched reluctance motor speed control drive system has a simple and firm structure, a wide speed control range, excellent speed control performance, and high efficiency in the entire speed control range, which is difficult for frequency conversion speed control induction motors. In addition, the rotor of the switched reluct...

Abstract

The invention relates to a cable winding system, in particular to a cable drum driven by a switched reluctance motor speed regulating system. The cable drum comprises a cable drum body, the switched reluctance motor speed regulating system and a speed reducer. The switched reluctance motor speed regulating system comprises a switched reluctance motor, a controller and a position detector; the switched reluctance motor is connected with the speed reducer, and a spindle output end of the speed reducer is connected with the cable drum body; the switched reluctance motor drives the speed reducer to provide a driving force for the cable drum so as to drive the cable drum body to pay off and take up cables synchronously along with a cable drum on mobile equipment; the position detector is arranged at one end of the switched reluctance motor and used for detecting rotation speed and angular displacement of a rotor in the switched reluctance motor; the controller receives rotation speed signals and angular displacement signals detected by the position detector and adjusts rotation speed and rotation direction of the cable drum by the aid of peripheral operations. The cable drum has the advantages of low energy consumption, wide speed regulation range and effectiveness in cable protection.

Description

technical field [0001] The invention relates to a cable winding system for mobile equipment, in particular to a cable reel driven by a switched reluctance motor speed regulating system. Background technique [0002] The cable reel is one of the essential components of industrial mobile equipment such as mobile cranes, and the running speed of the cable on the cable reel must be consistent with the running speed of the mobile equipment. In order to meet this requirement, the cable reel of mobile equipment is generally realized by the motor speed control system to drive the cable reel. [0003] Traditional variable frequency speed regulation induction motors need to adopt complex vector control systems in order to obtain speed regulation characteristics similar to those of DC motors. For some working conditions with large moment of inertia, high acceleration and fast speed, the cable reel driven by frequency conversion speed regulation induction motor can no longer meet this ...
