Product Description:

Okuma BL-MC140J-30SB Brushless servo motor is ideal for applications that require precise motion control. The motor is manufactured by Okuma, a company known for its trustworthy automation components. Its compact and durable construction guarantees reliable performance every time. Durability and lifespan are enhanced by the use of high-quality materials in the construction. An efficient torque generator, the motor runs on a permanent magnet field.

The BL-MC140J-30SB servo motor's rated continuous output power is 4.3 kW. The motor can only run on a 133V three-phase electrical system. The 200 Hz frequency ensures constant operation even when subjected to varying loads. The necessary energy for consistent performance is supplied by the current rating of 18.7 A. An ER encoder that is built into the motor, provides exact feedback for precise motion control. Class F insulation improves operational reliability by providing thermal protection. A key component of the motor's silky running is its 8-pole configuration. For maximum electrical efficiency, it has a star winding configuration. The permanent magnet field architecture guarantees stable operation while increasing efficiency. Stable operation is helped by the improved winding configuration that lowers energy loss. The strong construction guarantees long-term performance thanks to its strong design.

Applications requiring precise control at high speeds are ideal for the BL-MC140J-30SB servo motor. Because of its brushless nature, it requires less maintenance and is more reliable when used continuously. The motor's consistent torque output dampens motion fluctuations. The stall torque of 13.7 N·m provides sufficient force for difficult activities. With a maximum speed of 3000 RPM, the motor enables swift and precise movement. In order to prevent internal components from being overheated, insulation class F offers better thermal resistance. The design allows for easy incorporation into automation systems that value efficiency and accuracy.
