Product Description:
The BL-MC150J-20SNA-A servo motor is built by Okuma and belongs to the BL Servo Motors series. As a permanent-magnet AC machine, it is installed in CNC machining centers and general automation lines to deliver programmed motion to linear or rotary axes. When coupled with a matched drive, the motor receives regulated three-phase power and feedback commands, translating them into repeatable shaft rotation for positioning, feed, or spindle duties within industrial equipment.
During continuous operation the winding is energized at a nominal phase voltage of 133 V, and under this electrical pressure the stator draws a rated phase current of 13.4 A. This electrical input is converted into mechanical output of 3 kW, enabling the shaft to maintain a synchronous speed of 2000 rpm. At that speed the motor can deliver a steady torque of 133 kgf·cm, allowing it to overcome cutting forces or accelerate loads without thermal derating. These interconnected ratings define the thermal and power match that must be observed when selecting an inverter and service duty cycle.
The transient envelope is set by a stall torque of 16.2 N·m, giving the axis extra low-speed force before movement begins. Magnetic structure uses 8 poles, producing smooth torque ripple characteristics and simplifying resolver computations in the controller. Rotor position and incremental speed data are supplied by a Type-ER encoder, so the drive can close its velocity and position loops without an external feedback device being needed.
