Product Description:

The BL-ME120J-40TBA is an efficient AC brushless servo motor that produces constant output. The servo motor is made by Okuma and is a small option for industrial automation tasks that need to be precise and last a long time. Its design makes sure that it works reliably and is easy to connect to different motion control systems.

The BL-ME120J-40TBA servo motor has a rated power output of 4.0 kW and runs at 4,000 RPM. Its rated torque of 9.55 Nm and remarkable stall torque of 12 Nm make it an excellent choice for motion control tasks that place a lot of strain on the motor. The motor can handle up to 200V AC and a rated current of 20.8 A. This makes sure that it uses power efficiently and works reliably when it's on all the time. The motor has eight poles, which help it run smoothly and be controlled precisely. The frequency of operation is set at 267 Hz, which guarantees the best speed and economy. It has an insulation class of F, which means it can work in temperatures from 0°C to 40°C without getting too hot. It keeps its temperature performance stable thanks to a natural air-cooling system. The motor weighs around 15 kg, which makes it easy to handle.

The BL-ME120J-40TBA brushless servo motor also includes several functions. Because of its IP44 classification, it is resistant to solid objects larger than 1 mm and water splashes from all directions. For accurate positioning feedback, the servo motor>> comes with an incremental encoder that sends 2,500 pulses per revolution. Furthermore, it has an electric brake that makes sure the load can be safely stopped and held. Because of these features, the BL-ME120J servo motor is a reliable part for high-tech motion control systems.
