Field Coil - Ametek Lamb 115-334 2252 Because a HEPA filter loadsThis replacement field coil (Part #315334 02) is the stationary winding for the Ametek Lamb 115 334 motor series. The coil creates the magnetic field that drives the motor's armature as current passes through it. When a field coil burns out or opens up, the motor loses power or stops turning entirely, since the magnetic field it depends on is gone. Fitting a sound coil restores full motor power without the cost of replacing the whole motor assembly.
