Description
The Moog 2 Channel and 4 Channel Electronic Control Unit (ECU) is a radiation-hardened spacecraft controller designed to drive 3-phase stepper motors. Comprising Moog hybrid stepper motor controllers, an EMI filter, and six analog telemetry pass-throughs, the modular enclosure allows stacking two units to create a 4-channel configuration. It integrates complete power conditioning, pulse sequencing, and output driver stages with discrete direction and step controls, operating reliably across 22 to 36 volts in extreme space environments.
Best for
spacecraft engineers, aerospace system integrators, driving 3-phase stepper motors on spacecraft and multi-channel space mechanism motion control
