Choosing a Motor

Outrunner Motor Shaft Replacement

Outrunner Motor Shaft Reversal

HA Series Motor Shaft Replacement


Outrunner Shaft Replacement/Reversal

1.
Remove or loosen the setscrews at least two turns. Remove the collar
on the front of the motor.  Pull the rotating bell(rotor) from the rest of the
motor. There is a small wire washer behind the collar, don't lose it.

2.
If the rotor is tight in the motor, mount it to a plate and press it out.
It is best done on an arbor or drill press.

 

 

3.
The rotor will slide off the back of the motor.  The magnets
may pull the rotor back on the motor.  Hold the parts tightly
and pull them apart.

4.
Once apart be careful that the magnets in the rotor do not pick up
magnetic dirt.  Debris can get stuck and cause serious damage to
the motor.

5.
To remove the shaft use a plate or block with a hole to clear
the shaft.

6.
Lay the rotor as shown. Allow the shaft to hang though the block.

7.
Use a shaft or punch to push the shaft out. Be sure the parts are square
to prevent bending of the rotor.

8.
Push fit the new shaft in the rotor. If the shaft is not aligned properly
the bore can be damaged resulting in a wobbly rotor, which must
 be replaced. Use the press again if needed to install the shaft.

9.
If the motor is being used in the normal configuration, install the
shaft flush with the rotor face.

10.
Install the wire washer.

11.
Tighten the setscrew in the rotor. Slip on the collar and align the
set screw on the flat on the shaft. Use finger pressure as shown to
preload the bearings slightly by squeezing the rotor and collar toward
each other. Tighten the set screw in the collar while applying pressure.

Shaft Reversal

1.
Loosen the setscrews and remove the collar as in step 1 above.

2.
Turn the motor onto the rotor as shown. The plate must have a
hole to clear the shaft. Use the collar as a gauge for the shaft.

3.
The shaft will slide through the motor until the press touches the collar.

4.
Tighten the setscrew in the rotor. Slip on the collar and align the
set screw on the flat on the shaft. Use finger pressure as shown to
preload the bearings slightly by squeezing the rotor and collar toward
each other. Tighten the set screw in the collar while applying pressure.

5.
Install the supplied mounting accessories as pictured.
