Product Description:

The D062M-12-1310 is a frameless direct-drive servo motor manufactured by Kollmorgen as part of the DDR Direct Drive Motors series. By mounting the stator to the machine frame and bolting the rotor directly to the load, the unit removes mechanical backlash and belt stretch that limit conventional drives. This architecture supports high stiffness and precise positioning for rotary tables, electronic assembly heads, and optical inspection stages while keeping the overall envelope compact for integration into small equipment. The frameless format also allows the surrounding machine structure to provide the bearing support and mounting arrangement.

The motor delivers a continuous torque of 9.8 N·m and can reach a peak of 33.5 N·m for short acceleration bursts. The rated output speed is 500 rpm, and the static friction adder must be overcome during motion. Feedback is provided by a sine encoder whose resolution is 134,217,728 counts/rev; this pairs with an encoder accuracy of ±26 arc-sec and repeatability of less than 1 arc-second to support tight servo loops. Because the feedback scale is absolute, commutation and position are available immediately at power-up. A mid-stack rotor length provides the listed torque values while maintaining a compact axial profile.

Mechanically, the rotor pilots on a 155 mm base bolt circle and seats against a flange-mount interface that simplifies direct coupling to faceplates or index wheels. The assembly withstands axial compression loads up to 2,040 kg, which supports heavy fixtures without requiring additional thrust bearings. Moment of inertia is kept to 0.0071 kg-m², helping the drive achieve fast settle times in indexing applications. System power is supplied from a 230 VAC bus, matching common servo amplifiers. The housing diameter is 176 mm (6.93 in), and the motor uses a mid-stack configuration for direct-drive rotary axes that need compact packaging and low backlash.
