B-106-D-21 by Kollmorgen

The Kollmorgen B-106-D-21 is a high-performance industrial servo motor designed and manufactured by Kollmorgen as part of the Kollmorgen Goldline B and BH Motors series. It delivers a maximum rotational speed of Maximum Speed: 7500 RPM and maintains a Nominal Speed: 7500 RPM for rapid motion control. The motor provides a Peak Torque: 4.56 lb-ft (6.18 N·m) peak output alongside a Continuous Torque At 25°C: 1.23 lb-ft (1.67 N·m) rating for sustained operation. With a compact Frame Size: 70.0 to 190.0 mm envelope and a total Weight: 8.5 lb (3.9 kg), it achieves an optimal power-to-weight ratio. Integrated resolver feedback ensures precise position monitoring for demanding automation tasks.

Performance characteristics of the B-106-D-21 include a Resistance: 2.72 Ohm winding impedance and an Inductance: 14.4 mH for predictable current dynamics. The motor supports up to Peak Current: 12.6 Amps RMS surge capability, enabling rapid acceleration under heavy loads. Its Motor Constant (25°C): 0.145 lb-ft/W demonstrates efficient torque generation per watt, while the Maximum Torque Sensitivity: 0.37 N·m/Amp RMS ensures linear torque response. A low Rotor Inertia (kg·m^2): 0.000054 enhances dynamic response, reducing settling times in precision applications. Resolver-based feedback technology facilitates closed-loop control with high-resolution angle tracking and improved stability across the speed range.

Built for reliability, the B-106-D-21 offers an optional IP Rating: IP65/IP67 for dust-tight and water-immersion protection, extending suitability to harsh industrial environments such as food processing lines and outdoor equipment. Its robust mechanical design and standardized mounting facilitate seamless integration into existing automation systems and support modular machine architectures. The combination of compact size, lightweight construction, and advanced feedback features makes it an ideal choice for robotics, packaging machinery, and high-speed assembly applications. Supported by Kollmorgen’s extensive technical services, the B-106-D-21 meets rigorous performance and durability requirements, delivering consistent operation over prolonged duty cycles.
