Yuanfenron Brushless Motor Tester for E-Bikes & Scooters — 24V–72V Diagnostic Tool, Hall Sensor & Phase Check

The Yuanfenron Brushless Motor Tester is a pocket-sized diagnostic tool that quickly checks brushless motors, controllers, phase sequence, phase angle, and Hall sensors for 24V–72V e-bikes and electric scooters.

The Yuanfenron tester simplifies routine electrical troubleshooting for e-bike and scooter systems by combining multiple diagnostic checks into one compact device. Powered by a 9V battery (included) and compatible with 24V, 36V, 48V, 60V, and 72V setups, it helps technicians and hobbyists identify whether the motor, controller, Hall sensors, phase order, or phase angle is functioning as expected before replacing parts.

How does this tool identify a bad brushless motor or controller?

The tester applies simple electrical checks and signal indicators to determine whether a motor winding or the controller circuit is responding as expected. It isolates the problem by testing motor coils, controller outputs, and Hall-effect sensor signals so you can tell which component needs attention.

• Checks motor coil continuity and response to simulated inputs
• Detects controller output faults by observing signal presence or absence
• Identifies open or shorted windings quickly to avoid unnecessary replacements

Can it verify phase sequence and phase angle for proper motor rotation?

Yes — the tester reads the motor’s phase order and indicates whether the sequence matches ABC or abc color coding, and whether the phase angle is 60° or 120°. This helps confirm correct wiring and rotation direction before you reconnect the motor to its controller.

• Determines phase sequence (ABC vs. abc) to prevent reverse rotation
• Indicates phase angle (60° or 120°) for compatibility checks
• Useful during re-wiring, repair, or motor swapping tasks

Will it check Hall sensors and other common faults?

The device evaluates Hall sensor outputs and basic brake lever or switch signals to confirm whether the sensing elements are producing the expected responses. Identifying faulty Hall sensors early prevents erratic motor behavior and narrows down troubleshooting to a single component.

• Tests Hall-effect sensor signals for proper timing and consistency
• Verifies brake lever/switch signal presence when applicable
• Helps distinguish between sensor faults and controller failures

What are the physical specs and how portable is it?

The Yuanfenron tester is compact (10.5 x 7.5 x 2.5 cm) and built in a durable plastic housing for workshop use. It runs on a 9V battery included in the package, operates between -20°C and 50°C, and fits easily in a tool bag for field service or home repairs.

• Compact footprint for easy storage in a toolbox or bag
• Durable plastic housing for frequent handling in maintenance tasks
• Includes English manual and single 9V battery for immediate use

Who is this for: The Yuanfenron Brushless Motor Tester is aimed at e-bike and electric scooter technicians, repair shops, and DIY owners who need a fast way to diagnose electrical problems without expensive test benches. If you regularly service 24V–72V brushless systems and want to reduce guesswork on motor or controller failures, this portable diagnostic tool speeds up fault isolation and helps you make informed repair decisions.
