Product Description:

The BL-MC200E-12T is a three-phase brushless actuator built by Okuma for the BL Servo Motors series. By pairing a permanent-magnet field with integrated encoder feedback, the unit delivers tightly regulated shaft rotation for CNC slides, automated loaders, and coordinated robotics. It converts drive command waveforms into mechanical torque, supporting closed-loop motion in industrial applications that demand high accuracy and low maintenance.

Its continuous output reaches 2.4 kW, indicating the mechanical power that can be delivered to the load without thermal derating. At a rated armature voltage of 141 V, the motor draws 9.83 A under nominal load and maintains a rated speed of 1200 rpm. The rotor has a pole count of 8, allowing full torque production at a moderate electrical frequency while reducing iron losses in the stator. A Y-connected winding distributes phase voltage evenly across the coils. This winding arrangement interfaces directly with compatible Okuma transistorized drives. The permanent-magnet design avoids the energy consumption and heat associated with a separately excited field winding.

The motor supplies up to 21.0 N·m of stall torque, giving machine axes secure holding force before motion starts and during controlled dwell periods. Full-speed electrical excitation uses a base frequency of 80 Hz, matching the drive’s sinusoidal output tables. Feedback is provided by the ER-FC-2048D encoder, which produces 2048 pulses per revolution and transmits incremental position data to the controller. This resolution helps the controller detect small shaft movements during positioning. The motor carries a continuous-duty rating, permitting sustained operation under appropriate load and cooling conditions. Its tapered shaft supports secure coupling to compatible hubs while helping minimize backlash.
