NEMA Frame Number Suffixes

You’ll notice a letter suffix after the NEMA frame number, which NEMA regulations have standardized. These suffixes provide critical information about the motor, how it is mounted, its purpose, what type of shafts it has, and more. Here is a summary of what the suffixes mean:

C: type C face mounting on DE
D: type D flange mounting on DE
H: designated 56H motors to have two sets of 2F mounting holes, three in. and 5 in.
J: NEMA C face mount, threaded shaft pump motor
JM: face-mounted, close-coupled pump motors with specific dimensions and bearings
JP: type C face-mounted, close-coupled pump motors with specific dimensions and bearings
K: has a hub for sump pump mounting
LP or LPH: type P flange-mounted, vertical solid-shaft motors
M or N: flange mount for oil burner motors (6 3/4” flange for M, 7 1/4” flange for N)
P or PH: type P flange-mounted vertical hollow-shaft motors
R: drive end tapered shaft connection
S: Standard short shaft for direct connection
T: standard dimensions for this frame designation have been established
V: vertical mounting only
VP: type P-flange mounted, vertical solid shaft motor
X: wound-rotor crange motor with a double shaft extension
Y: particular mounting dimensions, contact manufacturer for details
Z: all mounting dimensions are standard except the shaft dimensions OR used to designate double shaft extensions, but in either case, contact the manufacturer for details.
