  • Patent number: 5760501
    Abstract: A structure for a compression driver motor assembly which utilizes a pot with an integral top plate and a pole cap, thereby reducing magnetic losses and permitting manufacture of a driver structure with fewer parts and reduced weight. A more efficient process for manufacture of the motor assembly is also disclosed. The pot is manufactured with an integral top plate which is adapted for use with a large pole cap. The pole cap is affixed to the top of a permanent magnet and forms the magnetic gap with the top of the pot. The magnetic circuit of the driver thus includes a permanent magnet, a pot, a magnetic gap and the pole cap. The motor assembly is assembled in a process requiring fewer steps and less elaborate tooling than the motor assembly of the prior art.
