Motiv Motor Controllers (Alpha-II, Bravo, Delta)

Motiv designs and delivers advanced motion control solutions for the extreme environments of space, from earth orbit to deep space to the cryogenic temperatures of the Moon. The Alpha-II Motor Controller is a single-axis, highly capable and flexible robotic motion control card supporting 3-phase BLDC or stepper motors, with an operational temperature range of -55C to +125C, 100kRad total ionizing dose radiation tolerance, and up to 6A continuous / 10A peak power handling; sample applications include on-orbit servicing robots and large planetary robotics such as the Mars 2020 rover arm. The Bravo Motor Controller is a compact, two-channel controller for stepper and brushless DC motors used in gimbals, positioners, robotics, focus mechanisms, and filter wheels, also rated to 100kRad. The Delta Motor Controller is a small form-factor controller with a mother-daughter board configuration adaptable to nearly any power output scenario, rated to 30kRad (100kRad available). Controllers can be tailored for specific radiation and parts-pedigree requirements to move quickly from lab to flight using the same architecture.
