I am testing your motor, and the results differ from the published data. What could be the reason for this discrepancy?

Dyno test results often differ from flight or static bench tests. Test conditions (including altitude, temperature, and humidity) significantly affect the data. Using ESCs from other brands may degrade performance since these motors are not optimized.

AI-Powered supplier vetting

SummaryThe supplier is a professional technical manufacturer specializing in motors and serving diverse industrial applications, including AGV, robotics, automobiles, medical equipment, and industrial equipment. It offers broad customization and 3D software design services, maintains quality assurance procedures, and has documented supplier corrective-action and finished-product inspection processes. Production information includes four production lines, a 3,300 m² plant, 50 quality-control staff, in-stock capability, and stated lead times of within 15 working days off-season and one month during peak season. However, no supplier-management-system certification, SDK, overseas warehouse, overseas agent or branch, overseas showroom, or valid manufacturing-capacity contract with related subcontractors is evidenced. Complaint handling has a procedure but no written records. Financial data availability is indicated for 2021–2023, but financial performance or credibility cannot be assessed from the provided information.

Supplier typeThe supplier identifies as a professional technical supplier and manufactures motors, including brushless, brushed, planetary gear, AC, worm gear, DC, and gear motors. Its products serve multiple industrial sectors such as robotics, AGV, automobiles, medical equipment, and industrial equipment, supporting classification as an industrial motor and engineering solutions manufacturer.

After-Sales capabilityThe supplier has a customer-complaint procedure, but no written complaint-handling records; it also has service corrective and preventive action procedures with followed records. It has in-stock capability and can participate in offline trade shows, but lacks overseas warehouses, overseas agents or branches, overseas showrooms, and reports zero countries with overseas services, indicating limited documented overseas after-sales coverage.

Production capacityThe supplier operates four production lines in a 3,300 m² plant, has 50 quality-control staff, provides in-stock capability, and states lead times of within 15 working days off-season and one month during peak season. It also has finished-product inspection instructions that are uniformly followed, although it lacks a valid manufacturing-capacity contract with its related subcontractors.

Customization capabilityThe supplier explicitly offers customization from samples, full customization, minor customization, customization from designs, and flexible customization, together with 3D software design services. This provides direct evidence of broad product-design and customization capability.

Product Q&A

Q:How to change the motor's rotation direction?

To reverse the motor's direction, simply swap any two of its wires.

Q:Is motor maintenance requiring the product to be sent to BOGONGSUN for processing, or can it be done anywhere?

All BOGONGSUN brushless motors are designed for customer maintenance. The technical video section of the support center provides detailed step-by-step instructions. Watch the video to learn how to replace bearings and shafts (full disassembly/reassembly). Bearing and shaft replacement kits are available for purchase.

Q:Do you have replacement bullet connectors for motor leads?

The replacement bullet connector can be obtained here.

Q:Which motor is most compatible with the DJIMM Phantom@ 2 series?

For optimal performance when paired with standard battery systems (3S voltage), we recommend using four (4) 2315 brushless motors with compatible adapters. This setup supports direct plug-and-play operation with original factory electronic speed controllers (ESCs). For more details, please refer to the "Installation Guide".

Q:Which motor is most compatible with the DJITM Phantom@ 3 series?

For optimal performance with standard battery systems (4S voltage), we recommend using four (4) 2315 brushless motors with compatible adapters. This setup directly integrates with the original factory Electronic Stability Control (ESC) for plug-and-play operation. For technical details, please refer to the Installation Guide.
