Product Description:

The BL-MC140E-30T is an industrial servo motor produced by Okuma within the BL Servo Motors series. The unit forms the electromechanical axis drive element in machining centers, lathes, and automated cells, where it converts commanded electric power into controlled rotational motion for position and velocity loops. By integrating with an Okuma CNC amplifier, the motor enables closed-loop automation stages to follow programmed profiles with minimal following error.

Its continuous mechanical capability is defined by a rated output of 4.3 kW, translating the supplied electrical energy into shaft work under standard thermal conditions. To sustain that output the drive draws a phase current of 18.7 A at a rated line level of 133 V, parameters that govern amplifier sizing and cable selection. Under normal duty cycles the shaft maintains a synchronous speed of 3000 RPM, so gear ratios can be chosen without overspeeding downstream components. For static holding or rapid indexing sequences, the motor can exert a stall torque of 13.7 N-m; this figure determines how much load inertia can be restrained without movement when position is commanded but no velocity is present.

These electrical and mechanical figures align with the motor’s classification as an AC Servo, denoting a permanently excited synchronous design that works with vector control algorithms. The designation “Control Type” code E signals compatibility with specific Okuma drive firmware that manages hall feedback resolution and torque loops. Because the factory-fitted option field is marked None, installers do not need to accommodate auxiliary brakes or encoders beyond the standard resolver. The branding of Okuma assures mechanical fit and parameter tables that match the broader BL Servo Motors series across multiple generations of controllers.
