B-802-B-21-B3-E1

The Kollmorgen B-802-B-21-B3-E1 is a high-performance brushless servo motor in the Kollmorgen Goldline B and BH Motors series, designed for robust industrial automation applications. As part of the Goldline B series, this motor features a three-phase brushless design optimized for precision motion control. With a nominal supply of 230V AC and a rated power output of 750 Watts, the B-802-B-21-B3-E1 delivers reliable torque and speed regulation. The motor’s rectangular NEMA flange housing provides a compact form factor and rigid mounting interface, making it suitable for a wide range of machine architectures. Engineered by Kollmorgen, this model combines durability and responsiveness for dynamic control loops.

The B-802-B-21-B3-E1 incorporates an incremental encoder type for accurate position feedback, supporting high-resolution control and repeatable positioning. Cooling is provided by natural convection, eliminating the need for auxiliary fans and reducing maintenance requirements. It operates at a nominal speed of 3000 RPM while drawing a current of 21 Amperes under rated load conditions. The motor produces a continuous torque of 3 Nm and is capable of maintaining this output across its duty cycle. Constructed with an IP65 protection rating, the housing resists dust ingress and water spray, ensuring reliable operation in harsh environments. Mounting is achieved via a flange mount interface, and the unit weighs 5 kg, enabling straightforward integration into compact assemblies.

Operational performance of the B-802-B-21-B3-E1 is characterized by smooth acceleration profiles and stable thermal behavior. The natural convection cooling system supports continuous duty operation without exceeding thermal limits, while the IP65 enclosure safeguards internal components from contaminants. The three-phase design minimizes torque ripple and supports bi-directional speed control for complex motion tasks. With a rated power of 750 Watts and a nominal voltage of 230V AC, the motor can sustain prolonged cycles without derating. The incremental encoder feedback allows drive systems to implement advanced control algorithms, maintaining precise speed and position under variable loads.

System integration is streamlined through compatibility with standard three-phase servo drives and motion controllers. The flange mount and standard connector locations simplify mechanical and electrical interfacing in automated equipment. Designed by Kollmorgen, the B-802-B-21-B3-E1 is ideal for applications in packaging, assembly, material handling, and robotics where compact size and reliable feedback are critical. Its combination of natural convection cooling, incremental encoder feedback, and IP65-rated housing make it a versatile choice for demanding manufacturing environments.
