Product Description:

The BL-MC200J-12SB is a servo motor manufactured by Okuma and supplied as part of the BL Servo Motors series. It is intended for precision positioning in machine tools, where the drive amplifier regulates current to achieve commanded torque and speed. By combining internal feedback, electrical commutation, and an integrated brake, the motor helps maintain axis accuracy and prevents unintended movement when power is removed. This type of construction is commonly used on feed axes, rotary tables, and similar mechanisms that require repeatable starts and stops.

The motor’s continuous power capability is 2.4 kW, allowing it to deliver the shaft energy needed for medium-capacity cutting and feed axes. At a rated velocity of 1200 RPM, it provides a balance between low-speed torque and thermal loading. Maximum holding torque while locked is 21.0 N-m. That torque level helps the axis resist movement at standstill when the brake is engaged and external force is applied. For single-axis applications that require up to 300% short-term overload, the matching drive unit is MIV02-1. The motor is supplied with a brake, so the shaft can remain secured during emergency stops or when a vertical axis is at rest.

Higher intermittent demand of up to 500% overload is supported when the motor is paired with MIV03-1. Position feedback is supplied by the incremental encoder model ER-J-7200D, which supports fine resolution for contouring paths and repeated reversals. The control electronics identify the motor through the letter J, so the correct motor data can be loaded automatically. This arrangement supports stable motion on feed axes that must accelerate smoothly, hold position accurately, and stop without drift between machining steps. Accurate feedback and automatic motor recognition also help the amplifier respond consistently during interpolation, rapid traverses, and low-speed finishing moves.
