AI-Powered supplier vetting

SummaryLunyee is identified as a Chinese manufacturer/factory of electric motors, drives, engraving and CNC-related equipment. The supplier reports broad export activity, with exports representing 71%–90% of total sales, and serves markets across multiple regions. Stated annual output includes DC motors, hub motors, engraving machines, AC motors and linear actuators, with off-peak lead time within 15 working days. The company describes after-sales capabilities including parts and service support, equipment refurbishment, system audits, maintenance refresher training and emergency site service. Its materials also emphasize customer satisfaction, long-term relationships and continuous technology upgrades. However, no certification information is provided, and the evidence is insufficient to assess financial credibility or customization capability. Customer references are mentioned, but no named customers or verifiable case details are supplied.

Supplier typeThe supplier is explicitly classified as a Manufacturer/Factory and is legally organized as a limited company in China. This supports direct manufacturing capability rather than an exclusively trading-oriented profile.

After-Sales capabilityThe supplier explicitly reports equipment refurbishment, system audits, maintenance refresher training, 24/7 parts and service support, continuous technology upgrades and emergency site service. These stated services indicate a developed after-sales support offering.

R&D capabilityThe company describes innovative manufacturing means, continuous technology upgrades and more than 15 years of innovation in electric motors and drives. These statements provide explicit support for ongoing technical development, although no quantified R&D evidence is given.

Production capacityThe supplier is identified as a factory offering multiple motor and machinery products, with stated annual output of 7,500 DC motors, 10,000 hub motors, 5,000 engraving machines, 8,000 AC motors and 6,000 linear actuators. It also reports an off-peak lead time within 15 working days, supporting a positive assessment of production capability.

Product Q&A

Q:Why does the robot chassis not move when controlled by the remote?

First, confirm whether the tail emergency stop switch is released; check whether the SWA lever is in remote control mode, then check whether the VRB knob is unlocked, and finally check whether the SWB gear switch lever is consistent with the control command.

Q:What should I do if the FR-mini remote control stops working due to a lack of power?

Please replace the battery of the remote control, and restore normal communication immediately after the remote control is powered on.

Q:Can the chassis shell be removed for modification purposes?

This chassis uses a non-load-bearing body, which means that the body does not support internal components. Removing the shell will not significantly impact the internal components, but we do not recommend doing so. If removal is necessary, please arrange for a professional to perform the removal. The company will not be held responsible for any damage caused by unauthorized removal.

Q:What should I do if both LED1 and LED2 indicators of the charger are off?

Please first check whether the input line interface of the charger is connected correctly and firmly; then check whether there is an AC input. Whether the battery has not been used for a long time, is over-discharged, or damaged; Replug the input and output line plugs, and the interval time is greater than 10 seconds to determine whether the charger is in protection state.

Q:How do I turn off the remote control when the remote control receiver is not turned off?

Please remove the remote control magnet and reinstall it.
