Radiation Hardened Stepper Motors
High energy, gamma radiation will attack all non-metallic materials in the motor. Lubricants, varnish, lamination bonding, and cable insulation deteriorate and ultimately crumble. Empire Magnetics' RH Radiation Hardened Stepper Motors combine the best available radiation resistant materials to provide motors with the longest possible service life in a radiation environment.
They have been tested to a total accumulated dose of 2 x 108 Rads. Frame size selection:
Radiation Hardened Stepper Motors are typically made in groups or families, the families are identified by the outer diameter or size of the square, these references are called frame sizes. In the American system, a 23 frame is a nominal 2.3 inches in diameter. For Radiation Hardened Stepper Motors less than one inch in diameter, the reference is typically known as a size. Herein is a list of the Radiation Hardened Stepper Motor frame sizes offered by Empire Magnetics Inc. and some of the characteristics of the group that will allow you to select from them.
