2.2 Mounting the HS56 to a Motor with a Fan Shroud
If the motor has only a fan shroud on the opposite drive end of the motor, use the mounting bolts on the end of the anti-
rotation arm to mount the HS56 to the fan shroud. Figure 3 shows the anti-rotation arm attached to the fan shroud.
1.
Arrange the anchor T-bolt as shown in Figure 4. Slide the anchor bolt into the fan shroud through an available vent.
2.
Rotate the T-bolt 90° so the bolt catches the inside of the fan shroud.
3.
With the anchor T-bolt positioned in the fan shroud, place ¼" washer over the bolt, tighten the hex standoff.
4.
Insert anti-rotation rod end into the Hex standoff and tighten.
The anchor bolt is designed for minimum ¼ inch of clearance between the fan and the
fan shroud. If there is not ¼ clearance the fan may hit the anchor bolt head on the
inside of the fan shroud. See drawing below. The minimum shaft length for fan shroud
mounting is 2.65".
5.
Slide the HS56 onto the accessory shaft.
6.
With normal torque, tighten the set screws holding the encoder on the accessory shaft. The anti-rotation arm should be
parallel with the encoder and perpendicular to the shaft. (For best holding performance, dimple or file a small flat on the
shaft under the set screw.)
