Description

Technical Field

[0001] The utility model relates to the technical field of controller structures, in particular to a controller structure capable of controlling dozens of motors. Background Art

[0002] A motor is a device that converts electrical energy into mechanical energy. It uses an energized coil (i.e., stator winding) to generate a rotating magnetic field and acts on a rotor (such as a squirrel-cage closed aluminum frame) to form a magneto-electrical rotating torque. Motors are divided into DC motors and AC motors according to the power supply used. Most motors in power systems are AC motors, which can be synchronous motors or asynchronous motors.

[0003] The existing motor controller is one controller controlling one motor, or one controller controlling a few motors. In the industrial field, a machine has dozens of motors, and a huge number of controllers are required. The installation is time-consuming and labor-intensive. A large number of controllers have a large number of circuits with the same functions, resulting in performance and cost redundancy. Therefore, we propose a controller structure that can control dozens of motors with one controller. Utility Model Content
