Product Description

Okuma has contributed significantly to the growth of the factory automation and motion control industry in Japan and the world at large. The Japan-based manufacturer has years of experience in developing revolutionary products, with the CNC machine tools as one of the most popular. Others include CNC lathes and turn-mill machining centers. One of the servo motor series in its portfolio is the Okuma BL series. The AC servo motors that comprise this family are powerful devices that come in different gradations of torques and speeds for industrial use.

The BL-MS45E-30TN-A is one of the models of the BL motors designed and manufactured by Okuma. Its nominal speed is 3,000 revolutions per minute, and it has a rated continuous power output of 1.4kW. It is a three-phase servo motor with 6 poles and a stall torque of 4.9Nm. Its current rating is 6.49A and it is operated with a nominal connecting voltage of 143V. It also requires a frequency of 150Hz. According to the NEMA requirement, this servo motor belongs to insulation class F. This is why the maximum temperature of its winding insulation has a rating of 155^oC.

The maximum ambient temperature where the BL-MS45E-30TN-A is operated is 45^oC. Since it belongs in the BL family, it is compatible with an Okuma BL-D servo drive which serves as its drive controller. Its IEC frame size is 34-1, and its compatible Okuma encoder is the ER-FC-2048D. The maximum vibrating rating that is specified for its operation must be maintained, and the lubricant grease level in its bearings should be monitored. This can be used to test the motor’s vibration levels.
