FIFE 534738-001 DC Motor

Description

Product Introduction & Engineering Value

When a web-guiding system starts losing position or stops responding altogether, the motor is one of the components worth checking before replacing the controller. FIFE 534738-001 is a dedicated DC motor used in web-positioning equipment, particularly the Symat 50 configuration.

The documented motor selection is 1.3 A, and the DP-20 PLUS documentation associates this motor with a 14 kΩ control resistor and the Symat 50 mechanical assembly. That relationship is important when verifying a replacement rather than treating the motor as a generic DC actuator.

Technical Specifications

Maxcess’s DP-20 PLUS documentation specifically lists 534738-001 under the 1.3 A motor selection, with a 14 kΩ resistor and Symat 50 as the typical assembly.

Current aftermarket documentation also identifies 29L85626001 as the replacement for 534738-001.

Field Application & the “Trench” Experience

A realistic failure scenario looks like this: a converting line begins showing increasing web-position error. The operator adjusts the guide manually, but the correction becomes slow and eventually stops. The DP-20 controller still powers up and responds to the sensor, so the maintenance team checks the actuator chain rather than immediately replacing the controller.

The motor is removed and found to have mechanical resistance. After inspection, the team confirms that the installed motor is 534738-001 and that the controller is configured for the 1.3 A / 14 kΩ Symat 50 combination. A mechanically and electrically compatible replacement restores the guide’s ability to make controlled position corrections.

Specific applications include:

• Symat 50 web-edge correction on converting equipment.
• Roll-to-roll web guiding where lateral material position must be continuously corrected.
• Slitting and rewinding lines where web wander can affect finished-roll quality.
• Printing/converting equipment requiring motorized lateral guide adjustment.

The DP-20 PLUS manual confirms the Symat 50 association and the 1.3 A motor selection for 534738-001.

Transparency SOP: QA & Testing

For a New Surplus or refurbished 534738-001, a visual inspection is not enough. A motor can look clean while having bearing, commutator, winding, or cable problems.

Recommended test sequence:

1. Identity check
   Confirm 534738-001, manufacturer markings, shaft configuration, and cable arrangement.
2. Mechanical inspection
   Rotate the shaft manually and check for abnormal resistance, roughness, axial play, or unusual noise.
3. Electrical inspection
   Measure winding resistance and check for insulation faults before applying operating power.
4. Controlled run test
   Operate the motor using an appropriate FIFE/Maxcess test setup. Verify smooth acceleration, rotation, stopping, and absence of excessive mechanical noise.
5. System-level verification
   Where practical, test it with the relevant controller configuration. The DP-20 PLUS documentation associates this motor with the 1.3 A / 14 kΩ / Symat 50 configuration.

Important: Current aftermarket sources classify the original 534738-001 as discontinued and identify 29L85626001 as its replacement.

The Veteran’s Tech Trap Guide

⚠️ Trap #1 — Treating 534738-001 as an ordinary DC motor

The motor is part of a controlled web-guiding system. The DP-20 PLUS documentation assigns a specific 1.3 A / 14 kΩ configuration to the Symat 50 application. Don’t substitute a physically similar motor without checking the controller’s motor-selection parameters.

⚠️ Trap #2 — Ignoring mechanical shaft dimensions

This part is documented with a 4.5-inch shaft. A motor with the correct electrical characteristics but the wrong shaft geometry can create alignment and coupling problems.

PRO TIP: Measure the original motor before ordering: shaft length, diameter, mounting geometry, cable exit, and connector arrangement. Don’t rely on the part number alone when dealing with decades-old web-guide hardware.

⚠️ Trap #3 — Assuming the old number is still the current replacement

The original 534738-001 is listed as discontinued, with 29L85626001 identified as the replacement in current aftermarket references. If the application specifically requires the original part number, confirm whether the buyer needs an exact-number replacement or an approved successor.

Dynamic FAQ

What is FIFE 534738-001?

534738-001 is a FIFE DC motor used in web-guiding equipment. Maxcess documentation identifies it as the 1.3 A motor for the Symat 50 configuration.

What system uses 534738-001?

The motor is associated with Symat 50 web-guiding assemblies and is selectable through the DP-20 / DP-20 PLUS controller configuration.

What is the motor current?

The documented motor selection is 1.3 A. The DP-20 PLUS manual also specifies a 14 kΩ resistor for the 1.3 A motor/Symat 50 configuration.

Is 534738-001 discontinued?

Yes. Current industrial aftermarket references identify the part as discontinued by the manufacturer.

What replaces 534738-001?

Current aftermarket listings identify 29L85626001 as the replacement part for 534738-001. Confirm mechanical and electrical compatibility with the actual FIFE/Maxcess system before substitution.

Does New Surplus mean it has an OEM warranty?

No. New Surplus generally describes unused inventory rather than guaranteeing an active OEM warranty. Warranty coverage must be confirmed with the individual supplier. Current aftermarket listings, for example, provide their own warranty while noting that the original factory warranty may not apply.
