20BM220MBP41

The Sanyo Denki 20BM220MBP41 servo motor from the BL Super Servo Motors series provides a robust solution for industrial automation requiring high reliability and precision. Its 2.2 kW power rating enables sustained torque output, while the 220 V voltage specification ensures compatibility with common industrial power networks. The integrated DC 90 V holding brake delivers a 400 kg·cm holding brake torque, affording secure positioning under static load conditions. A smooth cylindrical shaft without keyway and sealed ball bearings combine to offer precise motion control and extended service life. Natural convection cooling maintains thermal equilibrium during continuous duty operation, making this motor well suited for demanding environments.

Detailed electrical and mechanical specifications define the performance envelope of the 20BM220MBP41. The motor draws 10 A current at 50 Hz frequency and achieves an overall 98% efficiency under nominal load. Its Insulation Class F rating provides elevated thermal endurance and reliable operation from -10 °C to +40 °C ambient temperature. The Flange Mounting (four through holes) mounting type simplifies mechanical integration, while the smooth shaft design eliminates backlash associated with keyways. Vibration tolerance rated at V15 or lower ensures stable operation in mechanically noisy settings.

Operational features include a continuous (S1) duty cycle for extended runtime without cooling interruptions. The servo motor withstands instantaneous torque surges up to 300% of its maximum continuous torque, accommodating abrupt load changes without performance degradation. Natural Convection Cooling supports continuous operation without the need for forced air or liquid cooling systems. Sealed ball bearings deliver reduced friction and maintenance intervals, enhancing uptime. The robust output characteristics of the BL Super series motor ensure repeatable positioning accuracy and consistent speed control under variable load conditions.

System integration is facilitated by a large circular military style connector for main power and a smaller circular multi-pin connector for control and feedback. The flange mounting footprint and smooth cylindrical shaft support direct coupling to gearboxes, pulleys, or jigs without extensive adapter hardware. Target applications include CNC machine tools, robotic arms, packaging machinery, and precision assembly lines in industrial automation environments. The combination of 20BM220MBP41, Sanyo Denki, and the BL Super Servo Motors series delivers a turnkey motion control solution for high-duty manufacturing processes.
