After reviewing the speed-torque curves for the ML motor with the BLH drive, this BE motor would be a suitable replacement and a close replacement. The ML motors had a 1000 line encoder; the BE motor with J encoder is 2000 lines.
Note the ML and BL were 2-phase servo motors and both would need to be replaced. A BE motor cannot work with a BL drive; a Compax3 or Aries drive cannot work with a ML motor.
As these products have been obsolete for quite some time and application requirements have changed (loading, machine cycle times, etc), it may be a good idea to have the local Parker ATC distributor re-size the application.
| Obsolete Product | Recommended Replacement Product | Notes | Notes 2 |
| ML-2340A | BE231DJ-KPSN or BE232FJ-KPSN | The motor dimensions are close. The BE motor has the same pilot diameter (1.5"), bolt circle diameter (2.625") and flange size (2.25"). The BE motor shaft is 1.25" long and a .094" square key. The ML-2340A had a metric 11mm diameter shaft with a 4mm sq key, 30mm long. BE motor limit is 5000rpm. If needing higher speed use SM23 motor. | The BE motor is a stamped lamination motor and not a housed motor. If the motor is being washdown at all, the BE is not a good choice. The SM232AE-KPSN (or SM232AE-KPSV for IP65 shaft seal option) or SM233AE-KPSN (or SM233AE-KPSV for IP65 shaft seal option) is a housed motor but also has higher rotor inertia. The SM23 standard shaft is 0.82-inch (20.8mm) long. |
| ML-2340B | BE231DJ-KPSN or BE232FJ-KPSN | The motor dimensions are very close. The SM motor has the same pilot diameter (1.5"), bolt circle diameter (2.625") and flange size (2.25"). The SM motor with the -L long shaft option is 1.25" long . The ML-2340B had an imperial .375" diameter shaft with a .125" sq key, 1.25" long. BE motor limit is 5000rpm. If needing higher speed use SM23 motor. | The BE motor is a stamped lamination motor and not a housed motor. If the motor is being washdown at all, the BE is not a good choice. The SM232AE-KPSN (or SM232AE-KPSV for IP65 shaft seal option) or SM233AE-KPSN (or SM233AE-KPSV for IP65 shaft seal option) is a housed motor but also has higher rotor inertia. The SM23 standard shaft is 0.82-inch (20.8mm) long. |
| ML-3450A | BE342KJ-KPSN or BE343LJ-KPSN | The motor dimensions are close. The BE shaft is 1.19" long, .500" shaft dia with a .125" sq key. The pilot was .06" thick on the ML motor; it's .093" on the BE. The BE and ML motors both have a 2.875" pilot, 2.74" sq mounting (3.875" bolt circle). The ML motor had a 3.39" sq flange; the BE motor has a 3.35" sq flange. The ML-A motor had a metric shaft, 15mm dia., 5mm sq key, 47.4mm long shaft. | The BE motor is a stamped lamination motor and not a housed motor. If the motor is being washdown at all, the BE is not a good choice. |
| ML-3450B | BE342KJ-KPSN or BE343LJ-KPSN | The motor dimensions are very close. The BE shaft is 1.19" long, .500" shaft dia with a .125" sq key. The pilot was .06" thick on the ML motor; it's .093" on the BE. The BE and ML motors both have a 2.875" pilot, 2.74" sq mounting (3.875" bolt circle). The ML motor had a 3.39" sq flange; the BE motor has a 3.35" sq flange. The ML-B motor had an imperial shaft, .5" dia., .125" sq key, 1.25" long shaft. | The BE motor is a stamped lamination motor and not a housed motor. If the motor is being washdown at all, the BE is not a good choice. |
| ML-3475A | BE343LJ-KPSN or BE344JJ-KPSN | The motor dimensions are close. The BE shaft is 1.19" long, .500" diameter. The pilot was .06" thick on the ML motor; it's .093" on the BE. The BE motor has a .125" sq key, .500" shaft dia, 2.875" pilot, 2.74" sq mounting (3.875" bolt circle). The ML motor had a 3.39" sq flange; the BE motor has a 3.35" sq flange. The ML-A motor had a metric shaft, 15mm dia., 5mm sq key, 47.4mm long shaft. | The BE motor is a stamped lamination motor and not a housed motor. If the motor is being washdown at all, the BE is not a good choice. |
| ML-3475B | BE343LJ-KPSN or BE344JJ-KPSN | The motor dimensions are very close. The BE shaft is 1.19" long, .500" diameter. The pilot was .06" thick on the ML motor; it's .093" on the BE. The ML-B motor had an imperial shaft, .5" dia., .125" sq key, 1.25" long shaft. | The BE motor is a stamped lamination motor and not a housed motor.

The BLHX used the X text based language. The Compax3 T30 uses IEC 61131-3 programming languages (Ladder Logic, Structured Text, Continuous FlowChart, Sequential Flowchart). The IPA uses AcroBasic text based programming language. The Gemini GV6K uses the 6K text based language.
*The S100V2 requires 208-240vac 3-phase input!
