Description
Technical field
The present invention relates to technical field of engineering machinery, particularly relate to a kind of controlling method of motor, controller, control system and hoist.
Background technique
At present; in engineering lifting field; the use of hoist is more and more frequent; in the process using crane gear; often there will be hoist overwork, the situation of motor accident extinguishing, as motor operates in 1000rpm; and now crane load amount exceeds motor output power now, then motor is easy to stop working.
In prior art, operator are needed rule of thumb to judge the actual situation of hanging between carrying capacity and engine output of hoist, if find, crane load amount exceeds motor output power now (namely motor will stop working), as shown in Figure 1, Fig. 1 engine throttle pedal structure of the prior art schematic diagram, operator need pedal 01 of stepping on the throttle rapidly, increase accelerator open degree, control unit of engine controls the fuel injection quantity etc. of motor according to the throttle opening information received, and then increase the output power of motor, prevent from stopping working.
But; this determination methods of the prior art; mainly rule of thumb judge by operator and operate; poor and the artificial reliability judged of the promptness judged also can not ensure; if error in judgement, motor accident extinguishing in craning weight of same process, shear leg loses driving force; even if having hydraulic system and mechanical lock protection, also easily cause certain danger.
Summary of the invention
Embodiments provide a kind of controlling method of motor, controller, control system and hoist, in order to prevent motor accident extinguishing, improve the safety in utilization of hoist.
