Major Functional Sections

A. DC Power Supply Section

• Provides the DC supply for operating the BLDC controller. The panel identifies a 48 V, 20 A SMPS, together with supply terminals and fuse protection.

B. BLDC Motor Controller Section

• Provides electronic motor control and switching functions, with panel controls for enable, constant speed, direction and braking. The motor phase terminals are identified as U, V and W.

C. PWM Speed Control Section

• Allows the user to vary the PWM command through a rotary adjustment knob and investigate its effect on motor speed and operation.

D. Digital Measurement Section

• Includes digital voltage and current displays for electrical measurements. The displayed values and measurement ranges depend on the installed meter configuration.

E. Hall Sensor and RPM Measurement Section

• Supports the study of rotor-position sensing and electronic commutation. A digital RPM meter is provided for observing motor speed, while TP1, TP2 and TP3 allow access to designated test signals.

F. Microcontroller Interface

• An Arduino Uno board is shown on the trainer. It can support microcontroller-related experiments, subject to the actual circuit connections and controller interface provided by the manufacturer.

7. Recommended Supply Items

The complete supply should include the trainer, compatible BLDC motor, required connecting leads, operating manual, circuit diagrams, experiment manual, and relevant microcontroller program files where applicable.

8. Important Technical Verification

• The panel specifies 1-phase AC, 415 V, 50 Hz. This is an unusual rating for a single-phase laboratory supply; confirm the correct input voltage with the manufacturer before connecting the equipment to mains.
• The 48 V DC, 20 A supply has a nominal output capacity of 960 W. This does not establish the motor's rated power.
• Motor wattage, rated RPM, controller ratings, meter accuracy and PWM frequency are not specified on the visible panel and should be confirmed separately.
