Definitions

  • the air gap 50 is a dimensionally tolerant location in the motor because it involves the running clearance of the coil. By locating the magnet ring in this area, the tolerance of this part is less stringent. Also, the magnet ring is a simple, open geometry. This facilitates the location and assembly of the magnets and the shaping of the final part. The concentricity of the ring to the piston bore can be fixtured during final assembly.
