Motor Controls

Frontgrade’s rad-hard Motor Controllers have a long heritage of supporting key missions over the past 20 years.  

The 2-Channel Universal Stepper Motor Controller (USMC) is suitable for driving two independent stepper motors or one dual-redundant motor pair. These motor controllers come in various configurations for driving either 2-phase or 3-phase and can be unipolar or bipolar in design. Our 4-Channel Electronic Control Unit (ECU) is developed on the zero-cogging motor technology that helps to significantly limit torque disturbances.  

We offer a 2-axis gimbal controller on the MRO, Solar Array Drive positioning control on the GOES-R, and ATMS controller for precise positioning on the NPOES. These reliable components provide lifetime assurance.
