Crane neck motors are divided into: trolley crooked neck motors (running on the rails, one on each side if the span is long), trolley crooked neck motors (running on the rails that come with the crane) Upward walking), lifting and tilting neck motors, (if there is a grab bucket, there is also an opening and closing tilting neck motor).
Introduction to the crooked neck motor:
The control circuits of the above crooked neck motors are both forward and reverse control, that is, the phase sequence of the stator power supply is exchanged, and a hydraulic crooked neck motor is connected in parallel with the crooked neck motor wiring, mainly to prevent When the crooked neck motor suddenly loses power, the crooked neck motor is used for braking due to inertial motion, commonly known as the brake crooked neck motor.
The crooked neck motor has a winding structure. The rotor circuit is connected to a resistor through a slip ring brush. It can be divided into several levels of control. The speed is adjusted by switching the resistance of the rotor circuit on and off. When starting, all resistors are equal. When input, the speed regulation circuit can be controlled by grading by cam switch, or speed regulation can be achieved through time relay, that is, automatic delayed gear shifting. In the highest gear, which is the fastest gear, all external resistors of the rotor are withdrawn.
