Product Description:

The BL-MP400J-25SBB Servo Motor created by Okuma rotates at a constant speed tied to the line frequency and ideal for precise speed control and positioning applications. The module comes under the series of BL Servo Motors.

The BL-MP400J-25SBB servo motor comes with an encoder which provides feedback on its shaft’s position, speed and direction. The rotational force it provides is 44.3 Newton which indicates the load it can handle. The input voltage required for the motor to run properly is 133 volts which defines the electrical potential needed. It has cooling fans which help prevent overheating by increasing the surface area for heat to dissipate. It is featured with a 4 pin primary connector for delivering electrical power to the motor which ensures a secure and reliable connection in industrial automation environments. Its internal winding design is EC34F-1 which affects magnetic performance, efficiency and response time. The operational frequency corresponds with the motor's speed and control strategy is 167 hertz. It has a flanged mount which allows for rigid and stable installation and the presence of multiple bolt holes offer flexibility for securing the motor firmly in various orientations.

The BL-MP400J-25SBB servo motor can output. 6.2 kW mechanical power which is relatively high that makes it suitable for powerful machines that require continuous operation under load. It is constructed to withstand harsh environments. The module is designed to use permanent magnets instead of electromagnetic fields. The optimal continuous speed the motor is designed to run is 2500 min⁻¹ which suggests it is built for applications that needs high speed and precise control. At full load the electrical current required is 55.2 A which helps produce more power but also demands heavy-duty wiring and a capable power supply or driver.
