– Couldn’t track down the datasheet, but SHINANOKENSI seems to go by Aspina Group these days. Check their site for any updates: https://www.aspina-group.com/en/contact/. Their catalog lists LA052-040 as a similar inner rotor brushless DC motor.

– This looks like a brushless DC motor setup—3 phase drive wires, 3 HAL feedback wires, one for power (vcc), and one for ground.

On the other side, it’s labeled HU, HV, HW, VCC, and GND—think of these as the motor’s social security numbers. For detailed specs, check out the product page at this link. The marking ‘DR-6236-249’ from Shinanokenshi probably now belongs to Aspina Group—just like a name tag in the tech world. If you need help along the way, you can always schedule a repair.
