Product Description

The Okuma brand is a well-known designer and manufacturer of CNC machine tools and products, including lathes, grinders, machining centers, and CNC controls. With years of experience in developing innovative drive solutions, Okuma has become an established creator of such products. The company is also the manufacturer of the Okuma BL series of servo motors. These motors come in a range of sizes, speeds, and torques, allowing users to choose those that are specifically tailored to their desired applications.

The BL-MC200J-20SNA is a three-phase AC servo motor designed and manufactured by Okuma as one of the motors in the BL series. It is designed with a nominal speed of 2,000 revolutions per minute and a stall torque value of 21Nm. Its rated current is 16.2A, and the value of its connecting voltage is 157V. This servo motor model is a product of insulation class F, according to the NEMA requirement. As a result, the maximum permissible temperature of its winding insulation is 155^oC. The rated continuous power output of the motor is 4.0kW, while the recommended frequency for its operation is 133 Hz.

The level of lubricant grease in the bearings of the BL-MC200J-20SNA must be checked regularly to test the vibration levels of the motor. Its IEC motor frame size is given as 34-1 by Okuma, and its control type is indicated as ‘J.’ The required ambient temperature for its operation is between 0^oC and 55^oC, and its surface temperature should not exceed 45^oC. It should be protected from harmful chips, coolants, and lubricating oils to optimize its operation throughout its service life. In addition, its maximum recommended vibrating rating must be preserved.
