Abstract

This application relates to electric equipment and its motion control method. The equipment includes: a control processing module; a motor; a transmission module controlled by the motor; The control processing module; the limit module is used to limit the limit position of the transmission module and feed back the limit position to the control processing module; the control processing module is used to analyze the speed information of the motor according to the current signal and the motor parameters of the motor. Limit position and speed information determine the current position of the transmission module, and control the driving parameters of the motor according to the current position. By analyzing the motor current information, the motor speed information is extracted from it, and then the current position of the transmission module is calculated according to the limit position. In the whole process, the position detection can be realized without adding additional hardware, and the speed control of the transmission module can be realized. It is possible to work stably and safely.

Description

technical field

[0001] The present application relates to the technical field of electric equipment, in particular to an electric equipment and a motion control method thereof. Background technique

[0002] The use of electric equipment is one of the essential means for hospitals to achieve modernization, such as medical pendants, operating beds, etc. For various motion and position control equipment, limit switches are usually used to control the limit of its moving parts, that is, limit switch components are fixedly installed at the places where the moving parts pass through and need to be limited. The range of movement of the moving parts can be limited to the range required by the work through the limit switch. Once the limit switch fails, it may cause damage to the equipment or accidents. Therefore, the stability and reliability of the limit switch is very important for various sports and It is very important for position control equipment.

[0003] Since the limit sw...
