A couple of thoughts - always protect the motor windings from heat and arc flash.
1) Use a bearing separator kit, it is a diamond shaped beveled puller. This clamps on the small space between the inner race and the motor windings and uses a puller to remove the inner race from the shaft.
2) Take the assembly to a weld shop and weld to small beads on opposite sides of the inner race. This will cause the race to expand then you can grab it with a pair of pliers and pull it off.
3) Carefully hacksaw a slight diagonal cut on the inner race so as not to damage the shaft, spread the inner race with a screwdriver and slide it off.
