Overview
The Allen-Bradley MPL-B520K-MJ22AA servo motor is a 400 VAC brushless AC synchronous motor designed for precision motion control applications. This 165 mm frame size motor features a keyed shaft and 400 VAC power requirements, combining high-performance speed regulation with low-inertia characteristics. The multi-turn high-resolution encoder is ideal for applications that measure both the degree of rotation and the total number of rotations.
Key Features
- Rated motor speed of 4000 revolutions per minute
- Multi-turn (hyperface protocol) encoder installed in the servo for absolute position feedback
- Shaft key/no shaft seal servo motor featuring 2 circular bayonet facing shafts
- No brake built in, optimizing dynamic response for coordinated motion
- 165 mm frame size with IEC metric mounting flange for standard industrial integration
- Connected by bayonet cable connections enabling SpeedTEC-ready quick-disconnect setup
