Product Description:

The BL-MH301E-12SB is one of Okuma’s most outstanding servomotors, featuring a highly durable motor chassis. It features a specialized spindle shaft, perfect for driving loads in form-fitting systems. As part of Okuma’s BL product line, this large servomotor runs on a three-phase system to reliably achieve its rated output values. Like all other servomotors, this machine depends on the generation of a varying magnetic field to induce mechanical force across the rotor. The rotor, which is the moving component of the servomotor, effectively drives loads during operation. For AC machines, the quantity that describes the ability of the rotor to drive loads is called the torque.

Whenever the BL-MH301E-12SB is connected to its rated terminal voltage, the shaft achieves a stable velocity of 1200 rpm. Compared to other BL servomotors, this speed is relatively low. The BL-MH301E-12SB has a relatively lower speed during operation because of its shaft design and winding construction. As a large motor, the BL-MH301E-12SB is optimized for high power and torque applications using a specialized output shaft. This BL servomotor has a corresponding power output of 3.5 kilowatts at the rated speed. Whenever the shaft achieves its rated speed and output power, the BL-MH301E-12SB draws a nominal current of 15.4 A continuously.

The BL-MH301E-12SB has a total of six poles, spaced 60 degrees apart. In AC machines, the poles play an important role in generating the varying magnetic field, which then induces force to make the rotor move. Similar to other original Okuma motors manufactured under the BL series, the BL-MH301E-12SB employs natural air convection to dissipate heat during and after operation. To obtain this BL servomotor with a one-year item warranty, inquire from Wake Industrial’s sales team.
