US 2014/0174607 A1 · RETENTION OF MAGNETIC PROPERTIES

Abstract

Methods, systems, and apparatuses for retaining magnetic properties of magnetic elements while undergoing manufacturing processes are presented. In one embodiment, a manufacturing fixture includes a temperature controlled region suitable for retaining a magnetic element. The manufacturing fixture also includes a cooling mechanism configured to maintain the magnetic element at an acceptable temperature range during a thermally active manufacturing process. The temperature controlled or stabilized region can include a structure configured to receive the magnetic element and a sensor, or sensors. In one embodiment, the sensor can be configured to measure an ambient temperature of the temperature stabilized region. In another embodiment, the sensor can be a magnetic sensor configured to determine a magnetic property of the magnetic element.

Dependent claims

A fixturing device for maintaining magnetic properties of a magnetic element during a thermally active manufacturing process, the fixturing device comprising:

a fixturing device housing having walls that define a cavity;
a magnetic element retaining feature disposed within the cavity and configured to retain the magnetic element within the cavity of the fixturing device housing;
a sensor configured to provide information in accordance with a characteristic of the magnetic element;
and
a cooling mechanism in communication with the sensor and having a transport conduit embedded at least partially within the walls of the fixturing device housing, the cooling mechanism configured to move coolant medium through the transport conduit and into thermal contact with the magnetic element during the thermally active manufacturing process in response to information received from the sensor.
