Portable Motor Rotation Tester – AC Solenoid & Coil Detection Tool
Quickly confirm motor rotation direction and solenoid activity with this compact AC Coil Detector. Designed for both professionals and home users, this non-contact magnetic testing tool takes the guesswork out of diagnosing circulating pumps, HVAC components, and other AC-powered motors — no batteries required.
Key Features
- Accurate Solenoid Detection: Reliably identifies energized motor and pump rotation states, supporting fast diagnostics during machinery maintenance without direct contact.
- Visual Rotation Indicator: A clear visual indicator confirms magnetic field presence and directional rotation sensing, making it easy to verify pump activity at a glance.
- Vibration-Resistant Magnet Design: The internal solenoid magnet performs dependably even in high-vibration environments — ideal for construction sites, automotive repair shops, and industrial facilities.
- Durable ABS Construction: Built from tough ABS plastic, this tester withstands daily job-site use while delivering precise magnetic disc rotation readings without compromising accuracy.
- Keychain Attachment Included: A built-in keychain loop keeps the tester within reach at all times, so it's ready for quick deployment wherever you need it.
- No Battery Required: Completely passive operation — just bring it near an energized AC coil or motor to get a reading instantly.

Frequently Asked Questions
Q: Does the AC Coil Motor Rotation Tester require batteries to operate?
A: No — this portable AC coil detector is completely passive. It draws on the magnetic field generated by an energized AC coil or motor to operate, so no batteries or external power source are needed.
Q: What types of motors or equipment can this solenoid tester be used on?
A: The tester is compatible with a wide range of AC-powered equipment including circulating pumps, HVAC solenoid valves, automotive relays, and industrial motors. It's suitable for both professional technicians and home DIY users.
Q: Is this motor rotation detector safe to use in high-vibration environments?
A: Yes. The vibration-resistant solenoid magnet inside ensures accurate, non-contact readings even in dynamic settings like construction sites, machine shops, or automotive repair facilities where movement and noise are constant.
Q: How portable is this AC coil detector?
A: Very portable — it measures approximately 6.3 × 2 cm (roughly 2.5 × 0.8 inches) and comes with a keychain loop so you can attach it to your keys or tool bag for immediate access on the job.
