Abstract

DC60 (13/09/54) Electric Motor Control Experiment for this invention that includes an electric motor training platform. Together with the spindle (ball screw) is moving according to the rotation phase of the electric motor. Can be connected to a PLC (PLC) by connecting both input devices, including push button switch, limit switch, relay (relay), thumb. Thumbwheel switches Various sensors found in the industry, both analog and digital and output type. With the magnetic contactor, motor, lamp, and power circuit connected to the electric motor, it will be rebuilt with the electric motor trainer attached to the screw rod. Turn (ball screw) and have a tachometer included Connecting to a PLC (PLC) to control speed and position, range of motion, electric motor control must be written. Programmable commands and commands PLC (PLC) to control the operation of the electric motor according to the program. According to this invention Containing Electric motor stand Together with the spinning axis (ball screw) is involved in the movement According to the rotation of the electric motor, the experimental panel can be connected to the PLC (PLC) by connecting to both the input devices, including push button switches, limit switches. (limit switch) relay (relay) thumbwil switch (thumbwheelswitch, various sensor sensors found in industry Both analog and digital (digital) and output are equipped with magnetic contactor, motor, lamp (lamp), and power circuit (Power) connected. To the electric motor will be rebuilt with the electric motor training platform attached to the spindle (ball screw) and a tachometer, connected to the PLC (PLC) for use in The Control of speed and position, range of motion, electric motor control to work, must be written. Program commands and commands PLC (PLC) to control the operation of the electric motor according to the instruction program.
