Frame 56 Planetary Gearboxes
Empire Magnetics Inc. prepares gearboxes to operate in the same environments as the motors and resolvers. We start with high quality planetary gearboxes. These units are selected to provide maximum torque capacity with the smallest practical volume. We then upgrade the materials construction and lubrication to meet the requirements of the environment. |

Gearboxes for stepper motors and brushless motors are designed for the accurate positional functions desired of such systems. All of the planetary gearheads provide "in line" power transfer so there is no offset from the motor shaft to the output shaft of the gearhead. Vacuum rated gearboxes have all the materials selected or replaced with items that are compatible with VC, VS, or VX grades. The VS and VX grades are cleaned in the same exacting fashion as other components of this vacuum level. For VX grade we offer dry film lubrications as an option, while the vapor pressure is lower on dry film lubrications, the wear life is also lower. The application specifics must be considered to make the decision. Planetary gearboxes are available for stepper motors from size 17 to size 65, adapted versions of these same gearboxes can be mounted to brushless servo motors as well. |
