Introduction

The Allen-Bradley MPL-B330P-SK74AA Servo Motor is part of the MP-Series family of industrial servo motors developed for automated motion-control applications. It is designed for machines that require repeatable movement and controlled dynamic response rather than basic open-loop motor operation.

The MPL-B330P-SK74AA has a 100 mm frame size and a specified weight of 4.60 kg (10.14 lb). Its compact form factor can be advantageous in machine designs where motor mounting space is restricted.

Typical applications include packaging equipment, assembly machines, material-handling systems, machine tools, robotics, printing equipment, and automated production lines. In a complete motion-control system, the motor works together with a compatible servo drive, feedback system, and controller to regulate the required motion profile.

For replacement applications, the complete catalog number should be confirmed before ordering. Motors with similar frame dimensions may have different electrical characteristics, feedback configurations, shaft arrangements, or system requirements.

Applications

The MPL-B330P-SK74AA is suitable for a variety of servo-driven industrial applications:

Application	Typical Function
Packaging Machines	Indexing, positioning, and synchronized motion
Assembly Systems	Repeatable component positioning
Material Handling	Controlled acceleration and movement
Machine Tools	Precision axis control
Robotics	Servo-driven motion axes
Printing Equipment	Speed and registration control
Production Machinery	Coordinated automated movement
Specialized Automation	Closed-loop motion control

The motor is especially useful where the machine requires frequent changes in speed, direction, or position rather than simple constant-speed operation.

Key Advantages

Accurate motion control
The MPL-B330P-SK74AA is designed for applications where controlled motor speed, torque, and position are important.

100 mm frame design
The 100 mm frame size provides a compact mechanical package for automated equipment where installation space is limited.

Responsive dynamic operation
The motor is appropriate for applications involving repeated acceleration, deceleration, indexing, and positioning.

Designed for integrated motion systems
The MP-Series architecture allows the motor to be incorporated into a suitable Allen-Bradley servo-control system.

Suitable for automated machinery
Its servo characteristics make it a good fit for packaging, assembly, material handling, machine tools, and other automated production equipment.

Useful for replacement projects
The MPL-B330P-SK74AA can be considered when maintaining or replacing an existing MP-Series servo motor, provided the electrical, mechanical, and feedback specifications match.
