Product Description:

The BL-MH101E-20T is a servo motor manufactured by Okuma as part of the BL Servo Motors series. Intended for axis and spindle functions inside CNC and other automated machinery, it converts drive current into tightly regulated rotation so that commanded paths are followed with positional accuracy. Integrated into Okuma motion packages, the motor supports synchronized moves, contouring, and continuous interpolation, acting as the prime mechanical element in closed-loop factory automation. This makes it suitable for coordinated axis work where speed changes and reversals must remain smooth during repeated machine cycles.

Rated shaft output reaches 2 kW, allowing the unit to power mid-range feed drives or light spindles without oversizing surrounding components. The stator is wound for a DC link of 152 V, which balances insulation demand against available bus levels in Okuma amplifiers. Continuous operating current is 8.4 A; this rms value guides fuse selection and thermal modeling inside the drive. Base speed is specified at 2000 rpm, offering adequate surface velocity while maintaining torque at low frequencies. That operating point gives the drive a practical balance between sustained torque delivery and responsive acceleration during feed moves. The rotor uses 6 magnetic poles, a count that affects inverter output frequency and influences cogging and torque ripple behavior during fine positioning.

The motor supplies a steady torque of 98 kg-cm, enough to sustain cutting forces or table loads without overheating, while a stall ceiling of 108 kg-cm accommodates transient accelerations and static holding demands. Its duty rating is Continuous, so the frame and winding insulation are sized for full-duty operation rather than intermittent peaks. Positional feedback is delivered by the absolute encoder model ABS-FB-D2048, which provides 2048 discrete positions per revolution and supplies true absolute data immediately after power is applied, removing the need for homing routines. The feedback system also helps the control maintain repeatable positioning during stop-and-go motion and synchronized axis transitions.
