Description

technical field [0001] The invention relates to the technical field of motors, in particular to a wireless control servo motor. Background technique [0002] The servo motor can control the speed and position accuracy very accurately, and can convert the voltage signal into torque and speed to drive the control object. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an actuator, and has the characteristics of small electromechanical time constant, high linearity, and starting voltage. It can convert the received electrical signal Converted to angular displacement or angular velocity output on the motor shaft. At present, servo motors have been widely used in the industrial field, and most of the servo motors are controlled by the servo drive provided by the manufacturer.

AI Technical Summary

Problems solved by technology

At present, servo motors have been widely used in the industrial field, and most of the servo motors are controlled by the servo drive provided by the manufacturer. Among them, the motion control card in the servo motor communicates with the servo drive through cables, including the transmission of motor control signals and The feedback information of the angle sensor, in the rotary motion system, the motion control card to the servo system often needs to pass through the conductive slip ring, which belongs to the application category of electric contact sliding connection, and is the precision for realizing the image, data signal and power transmission of two relative rotating mechanisms. Power transmission devices have been based on the principle of brush contact so far, which can easily transmit electrical signals. Due to the form of direct contact, the life of the slip ring is limited, and the speed of the slip ring is also greatly affected by the limitation of the contact material and contact temperature. It is difficult to meet the high-speed rotating equipment, and the contact brush is made of precious metal materials, so the cost is also high
