Product Description

Okuma is a global manufacturer of machine tools and factory automation products with its headquarters in Japan. It is known for its many CNC machine tools and products such as lathes, machining centers, grinders, and CNC controls. The Okuma BL series of servo motors are built with a broad range of speeds and torques for users to select the ones that are best suited for their applications.

The BL-MC200J-12T is one of the AC servos motors in the BL series by Okuma. It features a nominal speed of 1,200 revolutions per minute and a stall torque of 21Nm. It is equipped with 8 poles and requires a nominal input voltage of 141V for its operation. Like other motors in this series, this servo motor belongs to insulation class F, indicating that the maximum temperature of its winding insulation is 155^oC. Its rated continuous power output is 2.4kW, and it utilizes a rated current of 9.83A. Its control type is indicated as ‘J,’ and the nominal frequency for its operation is 80Hz.

The IEC motor frame size of the BL-MC200J-12T is indicated as 34, and its output shaft is 28-24mm, indicating that it is tapered. The testing of the vibration levels of the BL-MC200J-12T must be done frequently to prevent the overheating of the motor. This is done by checking the level of the lubricant grease in its bearings. The interior of the motor should not be exposed to chips, coolants, and lubricating oils as these can cause damage to it. It also requires an ambient temperature between 0^oC and 55^oC. To extend its service life, the specified vibration rating of the motor should be maintained.
