Product Description:

The BL-MC100E-20SB is an AC servo motor produced by Okuma within the BL Servo Motors series. It is intended for closed-loop axis control in machine tools and other automated equipment where precise torque and speed regulation are required. By combining permanent-magnet excitation with feedback devices supplied by the drive, the motor translates electrical commands into mechanical rotation that can be synchronized with multi-axis motion controllers across an industrial installation.

This model is wired for a 3-Phase mains interface, allowing balanced power delivery and lower conductor current per phase. Its stator accommodates 8 magnetic poles, so electrical frequency and mechanical speed remain proportionate while preserving torque density at moderate shaft diameters. Continuous operation draws up to 8.91 A when the windings are energized at a rated line potential of 133 V. The magnetic circuit is tuned for a fundamental excitation of 133 Hz, which sets the electrical angle period that the inverter must produce to maintain synchronous rotation. Together, these parameters define the motor’s thermal load, cabling requirements, and compatible drive ratings.

At its mechanical rating the shaft turns at 2000 rpm, delivering a continuous output of 2 kW while remaining within the allowable temperature rise of the winding insulation. A peak holding capability of 10.8 N·m stall torque provides margin for momentary load surges or position stabilization without motion. The control identifier E designates feedback scaling and commutation data used by Okuma drives to align current vectors with the rotor’s magnetic field. These figures give system integrators the information needed to size gear reductions, configure acceleration ramps, and verify that the connected inverter can supply adequate voltage, current, and control bandwidth during all commanded duty cycles.
