Product Description:

The model BL-MC300J-20SB is a 3 phase Servo Motor with a 6.0 kW rated output. It delivers a continuous speed of 2000 RPM and features a stall torque capacity of 31.5 N·m. The motor is engineered for efficient and stable motion control in demanding industrial environments.

The BL-MC300J-20SB servo motor operates at a rated current of 28.6 A AC and a voltage of 133 V. It runs at a rated frequency of 133 Hz and includes 8 poles which support smoother torque delivery. The motor uses a star (Y) winding connection and is classified under insulation class F. It conforms to the IEC34-1 standard for rotating electrical machines. A permanent magnet rotor enhances the energy efficiency and torque density of the system. The shaft of the servo motor is a keyless round design with a center tapped hole that enables precise coupling and alignment. Its front face features a square flange mount with four bolt holes. The motor includes circular industrial multipin connectors for both power input and encoder feedback. This ensures fast secure electrical connections in industrial setups. The rotor is built with high strength permanent magnets for reliable performance. The frame is die cast aluminum with a black protective coating. This coating offers both durability and corrosion resistance in industrial conditions.

The Okuma BL-MC300J-20SB servo motor includes sealed ball bearings to ensure long operational life with reduced maintenance. The housing is optimized for thermal efficiency and mechanical protection. This model is compatible with horizontal base mounting and supports optional flange installation. The construction of the BL series servo motor supports vibration resistance and stable operation under continuous loads. The shaft and mounting configurations make it suitable for precision automation tasks.
