Problems solved by technology
[0003] (2) Due to the high vibration intensity, the damage rate of the contactor and the mechanical part of the relay is extremely high
[0004] (3) The acceleration of the motor is controlled by the controller or the time relay, which causes the motor to start at several times the rated current, and the reverse braking current is also very large, and it is common to burn the motor
[0005] (4) The motor has no other protection except over-current protection. The motor runs under overload for a long time, and the damage rate of the motor carbon brush and slip ring is extremely high, which seriously threatens production.
[0006] (5) The motor often operates under high current conditions, which not only has a large mechanical impact, but also consumes astonishing power

The invention relates to a rotor controller, especially relates to a rotor controller of a coiling motor, and belongs to the field of rotor control equipment. The rotor controller comprises a box, wiring device and a control device. The box mainly comprises a box cover, a hinge, a box bottom, and a locking buckle. A side of the box cover and the box bottom is connected through the hinge, and the other side is connected through the locking buckle, so that a box-type structure which can be opened and closed is formed. The rotor controller of the coiling motor provided in the invention is applied in rotor resistance switching control of a three-phase AC coiling motor. Input signals can be introduced after logic compiling in an external line, and the rotor controller has a wide applicability. The rotor controller is characterized by simple contactless circuit, small volume, low cost, and good effect. Using a structure of the hinge and the locking buckle, the box is convenient to be opened and closed, and the structure is simple and easy to use.
Description
technical field [0001] The invention relates to a rotor controller, in particular to a winding motor rotor controller, which belongs to the field of rotor control equipment. Background technique [0002] At present, in the existing technology, whether it is AC or DC, most of the electrical control of lifting equipment adopts a contactor control system with contactors. The control is backward, the lines are messy, the failure rate is high, and maintenance is difficult. The main manifestations are: (1) Frequent actions, contactor contacts and coils often burn out, causing fires in the circuit, or contact adhesion, and major equipment damage and other safety accidents. [0003] (2) Due to the high vibration intensity, the damage rate of the contactor and the mechanical part of the relay is extremely high. [0004] (3) The acceleration of the motor is controlled by a controller or a time relay, which causes the motor to start at several times the rated current, and the reverse ...
