Decoding the Part Number / Model Number

• SMW: Likely the motor series or family name.
• SIZE23: A standard NEMA (National Electrical Manufacturers Association) frame size. A “NEMA 23” frame typically has a face mounting plate of approximately 2.3 x 2.3 inches (57.2 x 57.2 mm) and a standard bolt pattern. This is a very common size for industrial automation, CNC machines, and robotics.
• BLDC MOTOR: Brushless DC Motor. This means it is an electrically commutated motor that offers high efficiency, high torque-to-size ratio, low maintenance (no brushes to wear out), and excellent speed control.
• BR 57ZW3Y52A21-BR-1: This is the manufacturer’s specific model code. It likely defines key characteristics such as:
  • Voltage Rating (e.g., 24V, 48V, 310V DC)
  • Speed/Torque Constant (Kt, Kv)
  • Winding Type
  • Shaft dimensions (diameter, length, flat)
  • Connector type
  • Feedback device (e.g., Hall sensors for commutation).
• P/N: 125644-1: The primary Part Number.
• REV G: Revision G, indicating this is the 7th revision of the design or documentation. This is important for ensuring you have the correct technical specs and drawings.
