Product Description:
The CH061A-13-3305 is a direct-drive rotary motor produced by Kollmorgen for the Cartridge DDR Motors series. It integrates stator, rotor, and encoder into a 188 mm square housing that seats against a NEMA frame recess. By removing belts or gearboxes, it drives the axis directly, improving stiffness and accuracy in packaging, circuit assembly, and similar applications. Single-turn digital feedback makes it compatible with high-resolution servo drives in multi-axis platforms.
At a winding temperature of 100 °C, the motor delivers a continuous shaft output of 33.8 Nm, sustained with only 10.0 A RMS of phase current. The built-in optical encoder provides 2048 cycles/rev so the drive can interpolate fine position increments during contouring moves. When powered at nominal line voltage, the rotor can reach 1600 rpm, and its magnetic circuit tolerates acceleration bursts up to 86.8 Nm before thermal or magnetic limits are reached. These overload events draw a peak current of 27.0 A RMS, giving ample headroom for rapid indexing while preserving coil integrity. At a cooler 70 °C winding temperature, the continuous torque rating moderates to 29.4 Nm, reflecting the normal relationship between resistive losses and allowable load.
A rotor inertia of 94.1 kg-cm² helps balance load inertia for stable velocity regulation, while the overall mass of 18.6 kg supports thermal dissipation. The winding set is designed for operation from a 400/480 Vac drive front end, allowing the higher input option to raise top speed without altering torque constants. BiSS serial feedback is provided through a BiSS Single-Turn channel, simplifying high-speed data exchange over one pair. Field wiring enters through a 90° rotatable connector, and the solid split-ring shaft, supplied without a key, mates to a clamping collar. A sealed stator bore keeps coolant spray and airborne particles away from the internal laminations.
