Product Description:

The BL-MS125E-20T is a Brushless synchronous motor that is manufactured by Okuma. It features a strong construction and a high torque density, allowing it to meet the stringent performance requirements of industrial automation.

The BL-MS125E-20T brushless synchronous motor is capable of producing 2.5 kW on a continuous basis and operates on 164 V due to its three-phase Y-connected winding operation. Due to the presence of a four-pole permanent magnetic field that provides support for its stall torque of 3.5 N·m and its rated speed of 2000 rpm, it is capable of producing power even when subjected to different loads. Every rotation, the motor features the Okuma ER-FC-2048D encoder, which is capable of delivering 2048 pulses. This ensures that the motor provides accurate position feedback. Making sure that it complies with the criteria of IEC 34-1 is necessary in order to guarantee that it is compatible with industrial systems all around the world. The pulley gear-mounted shaft is an important efficiency characteristic because it simplifies the mechanical design in direct-drive configurations. Because they direct electrical and encoder signals, the specialized ports facilitate integration with CNC controllers and other peripheral devices.

This BL-MS125E-20T motor's housing features cooling fins that provide passive temperature regulation, eliminating the necessity for additional cooling systems. Because of its 67 Hz frequency and F-class insulation, it maintains a consistent temperature even when subjected to currents of up to 1.1 A for extended periods of time during its operation. An emphasis on serviceability is seen in the design's standardized connectors and modular architecture. Its compatibility with Okuma's unified control systems allows for its simple implementation in high-precision machining settings, further establishing its place in sophisticated automation processes.
