Magnetizing permanent magnet modules

A method for magnetizing permanent magnets arranged substantially in a V-shape, the method comprising:

• applying a first magnetic field by performing the following:
• activating an open end magnetizing coil arranged near an open end of the V-shape and generating a first magnetic flux;
• activating a first side magnetizing coil arranged at a side of a first leg of the V-shape and generating a second magnetic flux;
• activating a second side magnetizing coil arranged at a side of a second leg of the V-shape and generating a third magnetic flux;
• and
• wherein the magnetizing coils are simultaneously activated and the second side magnetizing coil is activated in reversed polarity to the first side magnetizing coil.

A system comprising:

• a fixture made of magnetic material and comprising a passage configured to receive a permanent magnet module that includes permanent magnets arranged in a V-shape with a first leg, a second leg, and an open end between the first and second legs;
• an open end magnetizing coil arranged to be near the open end of the V-shape when the permanent magnet module is received in the passage;
• a first side magnetizing coil on a first side of the passage arranged to be substantially parallel to the first leg of the V-shape when the permanent magnet module is received in the passage;
• a second side magnetizing coil on a second side of the passage arranged to be substantially parallel to the second leg of the V-shape when the permanent magnet module is received in the passage;
• a control system configured to:
• energize the open end magnetizing coil, the first side magnetizing coil, and the second side magnetizing coil to apply a first magnetic field to magnetize the first leg of the V-shape;
• energize the open end magnetizing coil, the first side magnetizing coil, and the second side magnetizing coil to apply a second magnetic field to magnetize the second leg of the V-shape;
• and
• to activate the first and second side magnetizing coils with opposing polarity when applying the first and second magnetic fields.
