Kollmorgen DH083M
-
Product Name: Housed Direct Drive Rotary (DDR) Motor, DH Series, Frame DH083
-
Product Introduction: A large-diameter, short-length permanent-magnet direct drive rotary motor that couples directly to the load, eliminating gearboxes, belts and couplings. Designed for high-torque low-speed precision motion with zero backlash and near-zero maintenance.
Detailed content
-
Technical Specifications:
-
Line Power: 400/480 VAC (DH series)
-
Continuous Torque: 50.4 N·m (37.2 lb-ft)
-
Peak Torque: 160 N·m (118 lb-ft)
-
Maximum Speed: 500 rpm
-
Feedback: High-resolution sine encoder (optional multi-speed resolver)
-
Protection: IP65/IP67 shaft seal, built-in thermistor
-
Compliance: CE, UL recognized
-
-
Functional Features: Outstanding torque density via high pole count; direct load connection removes compliance and backlash; sub-arc-second repeatability with sine encoder; rugged resolver option for harsh duty.
-
Application Scenarios: Indexing tables, rotary transfer stations, semiconductor handling, packaging turrets, medical imaging gantries, machine tool C-axis.
-
Structural & Material: Aluminum/steel housing, large bore hollow shaft, integral stator/rotor lamination stack, precision bearings (single or dual).
-
Installation Requirements: Mount on machined perpendicular face; align load concentricity within tight tolerance; ensure axial/radial load within bearing rating; cabinet or open-machine mount with IP67 shaft side.
-
Usage Notes: Never mechanically preload through the hollow bore; verify encoder alignment before energizing; thermistor must be wired to drive for over-temp trip.
