Product Description:

The BL-ME200J-12TN-A is a three-phase AC servo motor produced by Okuma and supplied under the BL Servo Motors series. As a rotary actuator, it converts commanded current from an Okuma drive into controlled shaft torque and speed, enabling closed-loop positioning of axes in machining centers, handling modules, and other industrial automation equipment. The unit occupies a performance range where medium continuous power and moderate base speed are required, so it is used on feed axes that must sustain force through long machining cycles while fitting within compact mechanical envelopes.

Its continuous shaft capability is 2.5 kW, allowing the drive to deliver mechanical power suitable for mid-size tool spindles or gantry axes. At standstill, the motor can resist external loads with a 22 N·m stall torque, which supports holding force during contouring or clamping operations. The base mechanical output is reached at a rated speed of 1200 RPM, which corresponds to the electrical design frequency and winding configuration. Supplying the stator with 141 V line-to-line at that speed keeps copper losses within thermal limits while providing linear torque response. The motor uses a 3-phase connection to balance power flow and minimize pulsation, which supports smooth velocity control by the matching servo amplifier.

The motor’s construction supports reliable installation in industrial settings. Its housing carries an IP65 ingress rating, so dust intrusion and water jets do not affect the windings or bearings when the unit is mounted outside sealed cabinets. The active rotor is built with 8 poles, which, when energized at the BL drive’s fundamental 80 Hz electrical frequency, supports synchronous rotation while limiting torque ripple. Total mass is 20.9 kg, which affects inertia matching and mounting support requirements during rapid axis acceleration and deceleration.
