AL-E692B BLDC MOTOR CONTROL TRAINER WITH GUI INTERFACE 400W

AL-E692B – BLDC Motor with Control Trainer

Product Code: AL-E692B

1. Product Overview

The AL-E692B BLDC Motor with Control Trainer is an educational training system designed to demonstrate the operating principles, electronic commutation, speed control, direction control, and performance measurement of a Brushless DC (BLDC) motor. The trainer incorporates a motor driver circuit, PWM control interface, Hall sensor feedback connections, digital voltage and current meters, and an RPM measurement facility.

The system is mounted on a rigid aluminum-profile frame with a front-facing instructional panel, clearly identified test points, and circuit diagrams for practical learning.

13. Introduction to microcontroller-based motor control using an Arduino-compatible interface.
14. Troubleshooting of motor-control and feedback signal connections.

5. Working Principle

A Brushless DC motor uses electronic switching instead of mechanical brushes and a commentator. The electronic driver energizes the motor phases in a sequence that produces a rotating magnetic field. The permanent-magnet rotor follows this field and generates mechanical rotation.

Hall sensors detect rotor position and provide feedback to the controller. The controller uses this information to determine the appropriate switching sequence for the motor phases.

Motor speed can be adjusted by changing the PWM duty cycle supplied to the driver. The forward/reverse input changes the phase-commutation sequence to reverse the direction of rotation, provided the motor driver and control program support this function.

6. Mechanical Construction

• Rigid aluminum-profile frame.
• Bench-mounted construction with supporting feet.
• Front-mounted panel with printed circuit diagrams and terminal labels.
• Color-coded terminals for easy identification of control and measurement connections.
• Clearly separated power, driver, feedback, and measurement sections.
• Components arranged for convenient laboratory access and demonstration.

7. Safety and Operating Requirements

• Operate the trainer using the supply ratings confirmed by the manufacturer.
• Verify the AC input requirement before connecting the supply; the image's supply label should be checked against the actual unit.
• Ensure correct motor phase, Hall sensor, and controller connections before energizing the system.
• Use appropriate fuse protection and electrical safety procedures.
• Do not change motor wiring while the system is powered.
• Keep rotating motor parts guarded during operation.
• Use the trainer under qualified laboratory supervision.
