Motor model numbers are codes used by departments such as usage, design, and manufacturing to facilitate communication and simplify technical documentation. They typically consist of a type code, feature code, design sequence number, and excitation method code.
Motor type is designated by Chinese Pinyin letters, such as Y for asynchronous motors, T for synchronous motors, and Z for DC motors. Characteristic codes denote performance, structure, or application, such as B for explosion-proof types, YVP for variable frequency drive systems, and YD for pole-changing multi-speed motors.
The specification code typically indicates the center height, frame length, core length, and number of poles. For example, in YB2-132S-4H, 132 denotes a center height of 132 mm, S stands for a short frame, 4 represents 4 poles, and H indicates marine use.
Understanding the model numbering rules helps you quickly identify motor type, features, and specifications during selection.
