REXROTH MHD115C-058-PG1-BA

The REXROTH MHD115C-058-PG1-BA is an industrial AC synchronous servo motor designed for various automation applications requiring a balance of power output, precise positioning control, and a larger frame size compared to the MHD093C series. Here’s a breakdown of the information gleaned from the model number and some resources to help you find more details:

Manufacturer: Bosch Rexroth (formerly Rexroth)

Model Line: MHD115C+

Key Features (based on model number):

• AC Synchronous Servo Motor: Offers advantages over brushed AC motors, including:
  • Higher efficiency and reliability due to the absence of brushes.
  • Lower maintenance requirements.
  • Reduced electromagnetic interference (EMI).
  • Ability to achieve precise positioning and speed control.
• AC Powered: Likely a three-phase AC motor, operating on the standard industrial voltage (230VAC or 480VAC depending on the region).
• Frame Size: “MHD115C” indicates a larger frame size compared to the MHD093C series, translating to a potentially higher power output and torque. This makes it suitable for applications requiring more force alongside control.
• Power Output: Exact power rating is difficult to determine without a datasheet, but similar models in the MHD115C series might range from 4 kW to 11 kW (5 hp to 15 hp).
• Cooling Method: “PG1” in the code likely indicates:
  • P: Continuous torque (“Dauermagnet” in German, meaning permanent magnet)
  • G: Shaft seal
• Motor with shaft seal: This signifies the motor has a sealed shaft to protect the internal components from dust and debris, making it suitable for dirtier environments.
• Digital Servo Feedback (Possible): The “BA” at the end might indicate the presence of a digital servo feedback system with an encoder. This would enable precise positioning control. However, some resources suggest “BA” might be a generic code and doesn’t guarantee an encoder. Refer to the datasheet for confirmation.

Possible Applications:

• Machine tools (rotary tables, tool changers – larger): Precise positioning and control for tasks like moving larger rotary tables or operating tool changers in CNC machines and machining centers.
• Robotics (articulated robots – larger arms): Controlling the movement of larger robot arms for various tasks like assembly, sorting, and pick-and-place operations in industrial settings.
• Material handling (heavy-duty conveyors): Providing power and control for heavy-duty conveyors handling substantial loads.
• Food and beverage processing (filling machines – harsh environments): Precise positioning and control for operating filling machines or other equipment requiring accurate movements in potentially harsh environments (due to the shaft seal).
• Printing and packaging (registration, cutting – high-precision): Precise control of registration and cutting mechanisms in packaging machinery where a larger motor with higher power output is needed.
