 Custom motor shaft
We have a customer that purchased a used motor with a 56C mounting. After inspecting the motor it was found the shaft was bent. The customer shipped the armature and we're going to make a custom 56J shaft for the motor.
Before the shaft arrived we had the customer send the raw dimensions and produced this model. This is the armature assembly as it arrived. Here you can see the balancing epoxy putty that was used when the armature was dynamically balanced.

Pulling the lower bearing from the shaft. With the bearing removed you can see the puller clearance/step. This is the arrangement for pulling the upper (DE) bearing.

This is the drive end of the shaft with the bearing removed. This is the measurement and orientation for the armature core on the shaft. Press the armature core off the shaft. Even though the core is held in place with just a knurled surface it took a few tons to press it off.

This is the bare motor shaft. Now I can take all the required measurements. Started by cutting a length of 1018 cold rolled and center drilling it. Mounted the shaft between centers using a constant face driver and a live center. The factory shaft was done out of 1.1875 material. I could only source 1.25 so I'll have to turn it down.

Turned down to diameter. Knurled the shaft. The knurling will hold the core in place. Flipped the shaft and machined the lower end of the shaft.

Flipped the shaft back and machined the first bearing step. This is the upper 5/8 shaft portion. Machined the threaded portion along with the clearance relief groove.

Added the 7/16-20 thread. This is the new shaft along side the original. By making a new shaft we've changed a 56C into a 56J motor. Pressing the core back onto the shaft. Note that I'm using pipe to protect the shaft.

Pressed the bearing on. This is the completed rotor assembly.
