20BM090BBDT0 by Sanyo Denki

The Sanyo Denki 20BM090BBDT0 is a high-performance AC servo motor from the renowned BL Super Servo Motors series by Sanyo Denki. This brushless servo motor features a frame size of 90 mm and a robust flange-mounted design for straightforward integration into industrial automation systems. It delivers a rated power of 1.0 kW at a rated speed of 3000 rpm, providing a rated torque of 3.2 Nm for precise motion control applications. Operating on a 230 V three-phase supply, the motor draws 5.2 A under normal load conditions and supports ambient temperatures from 0°C to 40°C. Weighing approximately 4.5 kg, the 20BM090BBDT0 combines compact dimensions with a durable IP65 protection class rating.

Its performance-focused design includes an incremental encoder feedback device delivering 2500 pulses per revolution, paired with differential line drivers for enhanced signal integrity in noisy environments. Peak torque exceeds 6.3 Nm, enabling the system to handle brief overload conditions without compromising accuracy. Built-in thermal protection safeguards internal components against overheating, while the motor’s insulation level F rating tolerates internal temperatures up to 155°C. Vibration resistance meets JIS B 3502 industrial classification, ensuring stable operation under mechanical stress. The integrated holding brake option provides reliable load-holding capability when power is removed, essential for safety and positioning stability. Relative humidity tolerance ranges from 20% to 80% (non-condensing), protecting the motor in diverse environmental conditions.

Engineered for seamless integration, the 20BM090BBDT0 supports standard motion controller interfaces and mounts easily in CNC machines, pick-and-place robots, and assembly lines. The IP65 sealing offers protection against dust ingress and water spray, increasing uptime in harsh production settings. At elevations up to 1000 meters, the motor maintains consistent performance without derating, making it suitable for global deployment. Its balanced weight and frame dimensions facilitate retrofitting into existing equipment with minimal structural modifications. Ideal for industrial automation, robotics, and precision positioning applications, this motor delivers reliable operation and long service life in demanding environments.
