The Allen-Bradley/Rockwell Automation MPL-B4530F-SJ74AA is a brushless servo motor, initially set up with standard control features like an IEC metric mounting flange. This motor includes a brake that locks the shaft at zero RPM when turned off. The spring-set brake releases when voltage is applied to its coil. Part of the low inertia MPL series, this model includes a shaft key but lacks a shaft seal, which can be bought separately if exposure to liquids or fine dust is a concern. The seal is installed near the front bearing to shield the motor from lubricating oil and contaminants. In clean environments, the shaft seal isn’t necessary, and a lower IP rating suffices. Suitable for rigorous industrial use, the MPL-B4530F-SJ74AA boasts a high torque-to-size ratio, operates at 460 Volts AC, and runs at a speed of 3000 RPM. It also features a single-turn high-resolution encoder for precise positioning and control.
