Introduction: WhatsApp
NEMA JM/JP are single speed, totally enclosed, fan-cooled, continuous working duty, low voltage cage type three phase induction electric motors which comply with America NEMA MG1 standard and are designed for tight coupling pump. The motors have rigid installing frames and MENA JM/JP pump shafts. All series motors adopt casting iron frames, locked-bearing structure at driving end to limit shaft extension axial float. The efficiency meets America NEMA EPACT、NEMA PREMIUM standard, service factor is 1.25. The motor has passed America CC certification and Canada CSA certification.

NEMA Frame Number Suffixes
You’ll notice a letter suffix after the NEMA frame number and it, too, has been standardized by NEMA regulations. These suffixes provide key information about the motor, how it is mounted, what its purpose is, 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 have two sets of 2F mounting holes, 3 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: special 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
