Electric drag control circuit diagram

Electric drag refers to a method of using an electric motor to drive the working mechanism of production machinery to make it run. It includes power supply, electric motor, control equipment and transmission mechanism. In order to mechanically complete a certain process, the motor is required to complete different rotation modes according to the process requirements, and a certain type of circuit is used to connect the control equipment to meet the requirements. These circuits are the electric drag control circuits.

It includes: inching circuit, continuous operation circuit, forward and reverse circuit, multi-ground control circuit, step-down starting circuit, multi-speed asynchronous motor control circuit, position control circuit, etc. These are electrical drag control lines.
