REXROTH MKD071B-035-KG1-KN

The REXROTH MKD071B-035-KG1-KN is a Digital AC Synchronous Servo Motor with Brake designed for applications requiring precise positioning control, good power output in a compact design, and the ability to hold a position when not energized. Here’s a breakdown of the information gleaned from the model number and some resources to help you find more details:

Manufacturer: REXROTH (presently known as Bosch Rexroth)

Model Line: MKD

Key Features (based on model number and available information):

• AC Synchronous Servo Motor: Offers several advantages over brushed DC motors, including:
  • Higher efficiency and reliability: Due to the absence of brushes, reducing friction and maintenance needs.
  • Lower electromagnetic interference (EMI): Minimizing interference with other electronic devices.
  • Precise positioning and speed control: Suitable for applications demanding accurate motion control.
  • 
• Frame Size: The “MKD071B” suggests a medium frame size within the MKD series. This makes it suitable for applications where space is a consideration but requiring more power than very small motors.
• Power Rating: The “035” in the model number likely indicates a winding code related to the motor’s power output. Unfortunately, without referring to a specific datasheet or consulting Bosch Rexroth, it’s difficult to determine the exact power rating in terms of torque (Nm) or horsepower (hp).
• Speed Range: The maximum speed is likely to be around 3000 RPM, but the exact speed range might vary depending on the specific model and application.
• Resolver Feedback: The “G” is absent in the model number, suggesting this variant might use a different method (possibly an encoder) for position feedback, but a datasheet is recommended for confirmation.
• Shaft Key: The “K” in the model number indicates the motor has a shaft with a keyway. This allows for easy connection to a mechanical load using a keyed coupling.
• Standard Housing and Brake: The “N” in the model number signifies a standard housing design, and the “KG” together suggests the presence of a holding brake. This brake engages when the motor is not energized, allowing it to hold a position without continuous power input.

Possible Applications:

• Machine tools (rotary tables, tool changers): Precise positioning and control for tasks like moving rotary tables or operating tool changers in CNC machines and machining centers. The brake function can be useful for maintaining position during tool changes or pauses in operation.
• Robotics (articulated robots – medium-sized arms): Controlling the movement of robot arms for various tasks like assembly, sorting, and pick-and-place operations, where a motor with a balance of power, size, and holding ability is desirable.
• Printing and packaging (registration, cutting): Precise control of registration and cutting mechanisms in packaging machinery where a medium-power motor with a brake for maintaining position during pauses might be required.
• Food and beverage processing (filling machines): Precise positioning and control for operating filling machines or other equipment requiring accurate movements. The brake can be useful for maintaining position during filling cycles.
