Abstract
An integrated magnetic shield and bearing holder useable with electric motors includes a shaft portion and a cover portion extending radially outward from the shaft portion. The shaft portion includes an inner wall defining a channel and a ledge extending radially inward from the inner wall. The cover portion includes a first layer, a second layer extending substantially parallel to the first layer, a magnetic shield extending between the first layer and the second layer, and an outer wall extending from the first layer and/or the second layer such that a space is defined between the outer wall and the shaft portion. The cover portion includes one or more retainers coupled to the magnetic shield to restrict movement of the magnetic shield relative to the first layer and/or the second layer.
