Section 2
Front End Gearbox Drive Motor
2.1
Purpose
This section describes the procedures for the operation, maintenance, and repair of the XLi pinspotter’s
front end gearbox drive motor. This section also contains servicing and repair information for the brake and
encoder that are attached to these motors.
2.2
Scope
Front end motor problems, while uncommon, are generally covered under warranty during the warranty
period. Some of the motor’s components, while attached to the motor, are not actually part of the motor.
These are the brake and encoder assemblies. Replacement of these components is covered in this section.
The motors are provided in 50 Hz and 60 Hz configurations rated for continuous service. Both models are
rated at 1/3 horsepower; however, starting current and instantaneous torque may be 200-300% higher than
rated operating current. The QubicaAMF part numbers for the different motors are as follows:
Application
QubicaAMF Part No.
50 Hz Front End
088-000-115 (motor only)
088-000-145 (incl. brake & encoder)
60 Hz Front End
088-000-116 (motor only)
088-000-146 (incl. brake & encoder)
Replacement rotor assemblies and rebuilt motors are also available (see Section 2.3.4).
The table and sweep drives use identical motor & gearbox assemblies (088-000-172 for 50-Hz machines and
088-000-173 for 60-Hz machines) consisting of a gearbox and an encoder-equipped drive motor. The front
end motors have a brake as well as provisions for disengaging the brake and manual cranking. Front end
motors contain thermal overload protection that will interrupt current flow to the motor windings in the
event of a problem. A red reset button is located on the end of the motor. Allow the motor to cool before
resetting, and always attempt to determine and fix the cause of the overload before returning the motor to
service. The XLi front end motors are different from the back end gearbox motor, and are NOT
interchangeable.
The following repairs are described in the sections that follow. All other repairs are not covered in this
manual.
Replacing the brake
Replacing the encoder assembly
Replacing the rotor assembly
Whenever connecting a front end motor to a gearbox, be sure to use the shaft key, and if supplied with your
gearbox, the anti-fretting sleeve on the motor shaft. Also coat the motor shaft, anti-fretting sleeve, and the
inside of the gearbox input shaft with anti-seize compound.
Whenever attaching a front end gearbox to a drive shaft, be sure to apply a light coat of aluminum or copper
anti-seize compound to the drive shaft splines as well as to the inside of the gearbox input shaft.
For hand cranking of the table or sweep drive motors, the tab on the motor brake must be depressed and
held down to release the brake. Once you stop pressing on the tab, the brake re-engages
.
