MOTOR PART NUMBER – CROSS REFERENCE TABLE
When Compumotor introduced the OEM750/OEM750X, we
changed the part numbering system for some existing motors,
and introduced several new motors. The next table summa-
rizes the changes and additions. (The letters “n” represent
variables that can change, based upon the options ordered.)
Motor Size New Part Number Old Part Number
Size 23 OS2HA-SNFLY OEM57-40-MO
OS21A-SNFLY OEM57-51-MO
OS22A-SNFLY OEM57-83-MO
Double Shaft: OS2nA-DNFLY OEM57-nn-MO-DS23
Encoder: OS2nA-DNFLY-HJ OEM57-nn-MO-ENC
OS Series motors are the same motors as OEM57– Series
Motors; the new part number is the only difference.
New Motor Similar to Existing Motor:
Size 34 RS31B
–nnnnn
OEM83–62
–nn–nnnn
RS32B
–nnnnn
OEM83–93
–nn–nnnn
RS33B
–nnnnn
OEM83–135
–nn–nnnn
RS Series motors are similar (but not identical) in size and
electrical characteristics to OEM83 Series motors. The motors
differ in internal construction. Also, RS motors have cables;
OEM83 motors have flying leads, and are internally wired in
parallel.
