A compact 48 V servo order needs the complete suffix and drawing

This family’s 750 W versions do not all have the same length, feedback connection or shaft extension. Compare the full 80LCB075C suffix before reusing a cable or coupling. The manufacturer also supplies 200, 300, 400 and 1,000 W drawings, with configuration-specific dimensions rather than one universal compact package.

The 750 W options occupy two different motor envelopes

Each row is rated at 48 V and 3,000 rpm. Body length excludes the separately dimensioned shaft extension and the cable space.

24EA18 2.4 Nm / 22 A 111 mm 32 mm 800 ±20 mm lead length

Three reasons these suffixes should remain separate on a purchase order

The drive must match the feedback arrangement

The J5AA00 specification identifies a 2,500 ppr encoder, while the J5EA11 sheet identifies a 4,096 ppr arrangement and uses a different connector pin assignment. The 24EA17 and 24EA18 documents contain both a 4,096 entry and a “2500” feedback caption, so obtain the confirmed encoder configuration for those exact revisions. Do not choose a drive feedback setting from the shared 750 W rating.

The longer pair changes the shaft and key supply

The 24EA17/18 drawings show a 19 mm shaft diameter, 32 mm extension and no supplied key. The J5AA00/EA11/EA12 drawings show a 35 mm extension and specify a 6 × 6 × 25 mm key, with different packing or fitting instructions. Confirm coupling engagement, key supply and cable routing on the ordered drawing; these details are not implied by the common 80LCB075C prefix.

Maximum torque is not the continuous working point

The 24EA17/18 sheets list 2.4 Nm rated torque and 3.6 Nm maximum torque, with 22 A rated and 33 A maximum current. The J5AA00/EA11/EA12 sheets list 2.38 Nm rated and 4.77 Nm peak, the latter marked as a reference. No universal peak-duration allowance is provided. State acceleration time and the repeated duty cycle so the motor and drive can be checked together.

For the smaller frame, check the drawing before reserving axial space

200 W: 60LCB020C-J5AA00The specification gives 0.64 Nm, 5.3 A and 3,000 rpm at 48 V. Its body is 51.5 ±1 mm long, with a separately dimensioned 30 ±1 mm shaft extension. The face is 60 mm square with a 14 mm shaft and four 5.5 mm mounting holes on the illustrated 70 mm circle.
300 W: 60LCB030C-J5AA00The web table lists 56.5 mm body length, but the matching 031685 drawing shows 59.5 ±1 mm. Keep that discrepancy open until the supplied revision is confirmed. The agreed electrical row is 0.96 Nm and 9.1 A at 48 V and 3,000 rpm; electrical agreement does not resolve an envelope conflict.
400 W: 60LCB040C-J5AA00The drawing lists 1.27 Nm, 10.5 A and a 72.5 ±1 mm body, with the same separately dimensioned 30 ±1 mm extension. It identifies IP54 with a shaft exclusion and B-class insulation. Do not carry the 80-frame drawings’ F-class entry across to this smaller motor.

CATALOGUE OVERVIEW

About this motor series

Compact 48 V DC servo motors for machinery with restricted installation space. The manufacturer table lists 200, 300, 400, 750 and 1000 W versions at 3000 rpm. Match the exact encoder, shaft, connector and body length to the drive and machine drawing; the table includes multiple connection variants.
