Cryogenic Stepper Motors Frame Sizes

Cryogenic 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 Cryogenic Stepper Motors less than one inch in diameter, the reference is typically known as a size. Herein is a list of the frame sizes offered by Empire Magnetics Inc. and some of the characteristics of the group that will allow you to select from them.

Frame Size 17: Nominal outer dimension of 1.7 inches, these Cryogenic Stepper Motors are relatively low power useful for a wide range of industrial applications. Torque range of 13 to 26 oz-in. Cylindrical shaped motor laminations, with square end flanges front and rear. Since this motor does not have a housing, it is not available in all environments.

Frame size 23: Nominal outer dimension of 2.3 inches. Extremely popular size useful for a wide range of industrial applications. Torque range of 60 to 150 oz-in. Cylindrical shaped motor with square front flange.

Frame size 34: Nominal outer dimension of 3.4 inches. Power range of 80- 240 watts, useful for a wide range of applications. Torque range of 150 to 450 oz-in. Cylindrical shaped Cryogenic Stepper Motor with square front flange.

Frame size 42: Nominal outer dimension of 4.2 inches. Power range of 240-700 watts, relatively high power in the stepper motor range. Torque range of 400 to 1600 oz-in. Cylindrical shaped Cryogenic Stepper Motors with square front flange.
