Precautions:
1. Please operate the motor strictly within the specified working environment and the maximum allowable winding temperature range. Otherwise, permanent and irreversible damage may occur.
2. Avoid foreign objects entering the rotor; otherwise, abnormal rotor operation may result.
3. Before use, check whether all components are intact. If any parts are missing, aged, or damaged, stop using the motor immediately.
4. Ensure correct wiring and secure, proper motor installation.
5. Do not touch the electronic rotor area during operation to prevent accidents. When the motor outputs high torque, it may generate heat—be careful to avoid burns.
6. Do not disassemble the motor without authorization, as this may affect control accuracy or cause malfunction.
