#MotorTalkMonday – NEMA dimensions
Standardized NEMA Frame Numbers define a motor’s physical dimensions and mounting configurations, ensuring compatibility and easy replacement across manufacturers. In the USA, the National Electrical Manufacturers Association (NEMA) sets these standards to simplify motor selection.
When selecting a NEMA motor, it’s important to focus on critical mounting dimensions like foot and flange, including shaft height—not overall physical length, which can vary. These key factors determine whether a motor will properly fit your application.
NEMA frame standards ensure consistency in shaft dimensions, mounting hole locations, and bolt patterns, making motor replacement and upgrades hassle-free. Need help finding the right motor? ABB has you covered!
