Alignment of a motor with sleeve bearings is critical to long life. The following true/false questions are all related to the alignment of a sleeve bearing motor:

a. True or False: An electric motor shaft will operate on what is known as its magnetic center. This can be marked while the motor is under unloaded testing.

b. True or False: It is important to scribe the shaft for the total mechanical endplay of the motor shaft.

c. True or False: Some motors are equipped with shims that can be moved to either side of the sleeve bearing in order to achieve proper axial mechanical clearance.

d. True or False: The motor is aligned, and a decision must be made as to whether it is better for the motor to be centered between the mechanical end stops or moved very close to one end stop to be on magnetic center. Magnetic center is more important than clearance from the end stops.
