Product Description:
The DH083A-13-1210 is a Kollmorgen torque motor in the DDR Direct Drive Motors series. Designed for face mounting, the unit couples directly to the load through its straight through-bore shaft and face coupling, allowing compact installation on indexing tables or rotary transfer stations. A single-bearing design supports the rotor stack and eliminates gear lash, while the A-winding resolver supplies commutation and position data for compatible servo drives. This arrangement makes the motor a high-accuracy element in closed-loop industrial automation. It is well suited for rotary axes where compact depth and precise angular control are important.
The motor sustains a continuous output of 56.0 N·m at 40 °C and can reach a peak of 160 N·m for short acceleration bursts. These torque values are managed by a rotor with a moment of inertia of 0.0301 kg·m², which supports fast dynamic response without excessive overshoot. Power is supplied directly from a three-phase bus at 400/480 VAC, removing intermediate mechanical stages and reducing system losses. Even with its long rotor stack, the assembly weighs only 28.8 kg, which helps limit added mass on moving gantries or vertical axes. The combination of torque output and inertia is useful for indexing moves that require quick acceleration and controlled deceleration.
High-resolution feedback is delivered through the resolver, which divides each revolution into 134 217 728 counts/rev; this works with an accuracy of ±140 arc sec and repeatability of ±2.4 arc sec to support fine contouring tasks. The structure tolerates a dynamic axial load of 3360 kg, allowing the face mount to support thrust bearings or worm gears without compromising bearing life. Cabling exits through a 90-degree rotatable connector, so the connection can be oriented during installation. The frame has an 8.60 in. outside diameter, and the housing is not sealed, so an external enclosure is needed where contaminants are present. This open housing also helps reduce thermal resistance during high-duty operation.
