The motor casing in the IndraDrive Mi drive serves as the heat sink for the servocontrol system, which is attached to the long axis of the motor, adding only a small amount to the cross sectional profile.
This results in up to 30% less area required compared to other integrated systems where the electronics fit behind the motor, and over 50% less total space compared to a traditional servosystem with separate motor and drive packages. There is also less space needed in the control cabinet and less need for air conditioning. A single cable carries both power and Sercos communications. Only one cable comes from the cabinet when several IndraDrive Mi systems connect in series. Each additional axis is daisy-chained to the preceding axis with prefabricated connectors. The servodrives incorporate a Motion Logic system conforming to IEC 61131-3.
