4. The supplementary code is only applicable to motors with supplementary requirements.
For example: the meaning of the motor code of the product model YB2-132S-4H is:
Y: product type code, indicating asynchronous motor;
B: Product feature code, indicating explosion-proof type;
2: Product design serial number, indicating the second design;
132: The center of the motor is high, indicating that the distance from the axis to the ground is 132 mm;
S: the length of the motor base, expressed as a short base;
4: pole number, indicating 4-pole motor;
H: Special environmental code, indicating the marine motor.
Through the detailed introduction of the motor model above, I believe that we will know the type, characteristics, design serial number, motor specifications and environment used by the motor model.
