Product Description:

The BL-MC300J-12SNA is an AC servo motor manufactured by Okuma as part of the BL Servo Motors series. Designed for closed-loop axis control, the unit converts drive power into precise rotary motion while continuously returning position data to the CNC or PLC. Its use in automated machine tools, handling cells, and other motion systems supports repeatable positioning, coordinated multi-axis moves, and dependable cycle timing during industrial automation tasks.

Continuous mechanical output is rated at 3.6 kW, indicating the power that can be delivered without overheating at the stated duty cycle. Full output is achieved at a nominal speed of 1200 rpm, so torque and velocity are suited to medium-speed cutting and feed applications. A peak capability of 500% of rated torque allows short bursts for acceleration or load disturbances without stalling. Position feedback resolution reaches 24 bits per revolution, which gives the controller very fine position data when paired with suitable mechanical components. The encoder tracks rotor movement safely up to 6000 rpm, providing ample overspeed margin for alarm functions and quick indexing operations.

The feedback section operates from a regulated +12 V DC ±30% supply routed through the shielded two-wire encoder cable, and consumption stays below 1 W maximum, so extra cooling is not required. Absolute position values are retained for up to 7200 revolutions after power loss, which eliminates the need for a homing cycle at startup. Electrical matching with the Okuma MIV04-1 inverter supports straightforward integration because drive parameters and fault handling are already aligned. A four-core power cable carries stator current, while the shielded feedback link helps minimize electromagnetic interference so commanded accuracy can be maintained in high-energy machining environments.
