At 26V, the BJ42D15 26V10 delivers:

• BJ: Manufacturer or Series Code (often denoting a specific Asian OEM standard).
• 42: Indicates the faceplate dimensions. "42" corresponds to 42mm x 42mm (NEMA 17 standard).
• D: Body Length/Stack Type. In this classification, "D" typically represents a body length of approximately 34mm to 40mm (often referred to as a "short stack" or "D-length").
• 15: Designates the step angle or construction type. In this context, it usually refers to the standardized hybrid construction, but in specific OEM charts, it can denote the motor length code.
• 26V10: The critical electrical specification.
