Kollmorgen DD-MC2A-95070
Product Name: DD Series Direct Drive Motor Controller / Associated Component
Product Introduction: This part number is associated with Kollmorgen’s DD (Direct Drive) product ecosystem — either a controller/drive specifically tuned for DD torque motors or a reference/configuration item for DD motor systems. DD motors eliminate gearboxes/ballscrews for zero-backlash, high-precision motion.
Detailed content
Technical Specifications (Controller context if applicable):
-
Input Voltage: Typically 240–480 V AC 3-phase for DD drives
-
Output Current: Scales with motor (DD motors often high torque, moderate speed)
-
Position Control: Nanometer/arc-second level with high-res feedback (optical encoder/grating)
-
Communication: EtherCAT, Profinet, etc.
-
Protection: IP20 (drive), motor IP54/IP65 depending on DD model
Functional Features:
-
High bandwidth torque control: For direct-drive dynamics.
-
Vibration damping algorithms: Compensate for structural resonances.
-
Multi-feedback support: High-res encoders, sin/cos interpolators.
Material & Structure:
-
Drive: Standard AKD/SDR-style enclosure if drive unit.
-
Motor (DD): Frameless or housed, ironcore/ironless stator/rotor, epoxy encapsulation, high-energy magnets.
Working Principle:
Drive energizes stator windings to directly produce torque/force on rotor (no transmission); position feedback from integrated scale maintains closed-loop precision.
Application Scenarios:
Semiconductor wafer handling, optical inspection rotary stages, CNC rotary tables, telescope pointing, high-precision test equipment.
Installation Requirements:
-
Motor: Precision alignment critical (air gap uniformity for frameless).
-
Cabling: Separate feedback and power routing, shielded twisted pairs.
-
Grounding: Star grounding to minimize noise on high-res feedback.
Usage Precautions:
-
DD motors have very low inductance — drive must have appropriate d/dt control.
-
Avoid radial/axial load exceeding motor spec (direct bearing load).
-
Thermal management: stator heating affects magnet integrity; monitor winding temp.
