Overview
The Kollmorgen B-204-A-99-056 is a brushless permanent magnet servomotor engineered for high-performance motion control in demanding industrial applications. Part of Kollmorgen’s trusted Goldline series, this motor delivers exceptional torque and power density in a compact, low-inertia design. Operating on 230 VAC line power, it reaches 1900 RPM with a continuous power output of 0.82 kW, making it ideal for rapid acceleration/deceleration cycles and precision point-to-point positioning tasks.
Key Features
- Interior permanent magnet design: Delivers high torque density with low inertia (0.0001729 kgm²), minimizing settling time and improving response accuracy
- Rugged IP67 protection: Sealed against dust and low-pressure water jets, suitable for washdown and harsh industrial environments
- Integrated thermal management: Built-in thermostat monitors winding temperature; Class H insulation rated to 180°C
- Resolver feedback: Inbuilt resolver and servo amplifier interface enable reliable closed-loop position control
- Compact form factor: 13.6 kg mass with high torque-to-volume ratio simplifies space-constrained machine designs
- Optional fail-safe braking: Compatible with fail-safe brakes and front-mounted gearheads for extended functionality
