Internal Product Review
The BL-MC100J-20SB is an AC servo motor designed for continuous duty in demanding motion-control service. A 2 kW rated output paired with 2000 RPM rated speed gives the motor an excellent balance of response and usable power. Permanent-magnet field construction and 10.8 N·m stall torque make this model a strong performer for precise, high-load positioning.

Product Description:
The BL-MC100J-20SB is an AC servo motor produced by Okuma within the BL Servo Motors series. As a permanent-magnet, three-phase unit, it converts electrical power from a matched drive into controlled rotary motion for positioning axes on CNC machine tools and other automated equipment. The motor supplies feedback-compatible torque with rapid acceleration and deceleration, allowing motion controllers to maintain tight path accuracy in continuous production cycles.
The mechanical rating is 2 kW, indicating the maximum continuous mechanical power the shaft can deliver under nominal thermal conditions. Output rotation is stabilized at 2000 RPM, a speed selected to pair with ball-screw or belt reductions common on medium-inertia loads. During this operating point the stator draws 8.91 A from the drive while receiving 133 V line-to-line, so cable sizing and inverter capacity must support that current and voltage simultaneously. An internal eight-pole rotor, shown by the 8 pole count, shortens electrical angle per revolution; this increases torque density and quickens electromagnetic response, which benefits contouring moves that demand high bandwidth.
Static capabilities are defined by a stall torque of 10.8 N·m, giving the controller enough holding force for low-speed cuts or when the axis is clamped in position. Electrical commutation is synchronized at 133 Hz, the rated electrical frequency derived from pole count and mechanical speed, ensuring sinusoidal current remains in phase with rotor flux. The motor is specified for Continuous duty, so its thermal design supports indefinite operation at rated load without derating. Windings are connected in a Y configuration, providing a neutral point that facilitates balanced three-phase distribution and reduces phase-to-phase voltage stress.
