📌 Product Introduction

The Bosch Rexroth MKD025B-144-KG1-UN is a compact AC synchronous servo motor from the Indramat MKD series, designed for precise motion control in industrial automation equipment. It converts servo-drive commands into controlled rotary motion for applications such as machine tools, packaging machinery, material handling systems, and automated production equipment.

This model features a plain shaft with a shaft seal, an integrated holding brake, and resolver feedback with integrated absolute position detection. Its compact motor design supports accurate positioning and controlled movement when paired with a compatible servo drive and feedback system.

⚙️ Key Features and Applications

• Precise motion control: Supports controlled speed, torque, and positioning when connected to a compatible servo drive.

• Integrated feedback: Resolver-based feedback with absolute position detection supports position monitoring and control.

• Holding brake: Helps hold the motor shaft when the system is stopped; it is not a substitute for required machine safety measures.

• Compact construction: Suitable for machinery with limited installation space.

• Industrial applications: Used in machine tools, packaging equipment, automated handling systems, and production machinery.

❓ Frequently Asked Questions

Q1: Which servo drive is compatible with the MKD025B-144-KG1-UN?

A: Compatibility depends on the drive series, motor data, feedback interface, brake connection, and firmware. Confirm the motor's complete type code against the drive documentation before installation.

Q2: Does this motor have a holding brake?

A: Yes. This model is specified with a holding brake rated at approximately 1 Nm. Check the brake wiring and release voltage requirements before commissioning.

Q3: What feedback system does it use?

A: The model is specified with resolver feedback and integrated absolute position detection. The drive must support the corresponding feedback arrangement.

Q4: Can it replace another MKD025 motor directly?

A: Not necessarily. Compare the winding code, motor length, feedback system, brake, shaft design, connectors, and drive parameters before replacing the motor.

Q5: What should be checked before purchase?

A: Confirm the full model number, nameplate information, shaft and flange dimensions, feedback connector, brake condition, insulation condition, and whether the unit is new, surplus, or used.
