Standalone drive electronics from RUAG Space are the first choice for operating different types of mechanisms such as solar array drives, antenna pointing systems or thruster pointing assemblies. The Multi-Purpose Drive Electronics (MPDE) is a generic two-axes stepper motor controller optimized for high performance and smooth mechanical operation. It is compatible with a high number of actuators and available for different power bus voltages.
The MPDE is operated via a MIL-STD-1553B communication interface and is highly user-configurable. It offers different drive functions such as constant speed operation, drive to target or automatic trajectory tracking with the motors running either in half-, full- or micro-step mode.
RUAG Space offers various types of modular and embedded drive electronics with the motor driver either installed within the actuator housing or as part of a hosting unit such as an on-board computer system. Having the mechanism electronics part of the actuator housing offers low-cost drive trains especially for simple applications such as deployment mechanisms.
