JM JM designates a special pump shaft originally designed for a mechanical seal. $ Standard short shaft for direct-drive applications. The critical items on C face motors are the bolt circle (AJ dimension), rabbet diameter (AK dimension) and the shaft size (U dimension). The following are dimensional size charts for standard electric motor NEMA standard frames and configuration. Some shim manufacturers (Lawton and Accushim as example) rate their shim sizes by horsepower or frame size of the motor they support. Y  indicates that the motor has a special mounting configuration. Training Online Engineering What this means, is that all motors manufactured under NEMA specifications, will have the same dimensions, regardless of who manufactured the motor.

D The D flange/face mounted motor. The frame number relates to the “D” dimension (distance from center of shaft to center bottom of mount). By NEMA definition, two—digit frame numbers are fractional frames even though 1 HP or larger motors may be built in them. By NEMA definition, two—digit frame numbers are fractional frames even though 1 HP or larger motors may be built in them. NEMA (National Electrical Manufacturers Association) frame size refers to mounting only and has no direct bearing on the motor body diameter.
