AC DC Motor Driving Control Trainer, featuring an AC motor, DC motor, frequency converter, coupling, torque and speed sensor, reducer, sprocket, chain, weights, and more, is designed for comprehensive control experiments of AC and DC motors, including mapping their characteristic curves. The control unit uses relay control and Siemens PLC. Ideal for universities, colleges, vocational schools, and technical schools, the trainer enables:

1.Understanding the structure and working principles of mechanical and electrical transmission control
2.Characteristic testing of AC and DC motors
3.Relay control experiments for AC and DC motors
4.Upper computer control experiments for AC and DC motors
5.PLC (Programmable Logic Controller) experiments
6.Mechanical transmission experiments

Highlights:

1.This system intuitively displays the entire process of driving control in a mechatronics system.
2.Dual control modes: The relay control mode helps students master traditional relay control principles and wiring, while the PLC control mode offers simpler wiring, significantly reducing preparation time for experiments.
3.The experiment software supports real-time tests, results saving, printing, and simulation. It can generate four types of characteristic curves (both real-time and historical): T-n curve, t-T curve, t-n curve, and t-V curve.
4.The optional PLC experimental part integrates a programmable logic controller, programming software, and analog signal/analog quantity components to complete basic PLC instruction experiments, switch signal/value experiments, analog signal/quantity experiments, and communication experiments.
