Precautions
-
Always operate the motor within the specified environmental conditions and winding temperature limits to avoid irreversible damage.
-
Prevent foreign objects from entering the rotor area to ensure stable operation.
-
Before use, inspect all components. Do not operate if parts are missing, aged, or damaged.
-
Ensure correct wiring and secure installation of the motor.
-
Do not touch the rotor or electronics during operation. High torque output may cause heat—avoid burns.
-
Do not disassemble the motor. Unauthorized disassembly may affect control accuracy or cause malfunction.
