Product Description:
The BL-MC95J-20T belongs to the BL Servo Motors series manufactured by Okuma. As a servo motor, it converts controlled electrical input into precise rotary motion for CNC feed axes and positioning tables in industrial automation systems. The permanent-magnet rotor and closed-loop feedback support tight velocity and torque regulation, making the motor suitable for continuous-duty machine tool applications that require accurate, repeatable movement.
The unit delivers a continuous mechanical output of 2 kW, providing adequate shaft power for mid-sized lathes, milling machines, and positioning mechanisms. Under rated operating conditions, the stator draws 8.91 A, which must be considered when selecting a compatible drive and power cable. The shaft reaches a maximum speed of 2000 rpm, providing the velocity range needed for controlled feed motion and rapid positioning. The rated terminal voltage is 133 V, so the connected drive and insulation system must accommodate this operating level. At standstill, the electromagnetic circuit can produce 9.6 N·m of stall torque, allowing the shaft to resist a static load within the motor’s thermal limits. The permanent-magnet AC servo motor uses a Y-connected winding for continuous operation in industrial machinery.
An Okuma ER incremental encoder returns position and movement data to the CNC, allowing the controller to correct deviations during operation. The rated electrical frequency is 133 Hz, corresponding to the motor’s rated rotational speed and pole arrangement. Torque is produced by a rotor with 8 poles, which promotes smooth rotation and useful torque density when powered by a three-phase supply. Compliance with IEC 34 supports integration with recognized motor performance, insulation, and testing practices. A tapered output shaft promotes concentric alignment when the motor is coupled to a compatible pulley, gearbox, or machine mechanism, helping reduce runout at the driven connection.
