REXROTH MHD090B-058-NG0-UN

The REXROTH MHD090B-058-NG0-UN is a brushless synchronous motor designed for industrial applications requiring reliable and efficient operation in harsh environments. Here’s a breakdown of the information gleaned from the model number and where to find more specifics:

Manufacturer: Bosch Rexroth (formerly Rexroth)

Model Line: MHD090B

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

• Brushless Synchronous Motor: This design offers several advantages over brushed AC motors, including:
  • Higher efficiency and reliability due to the absence of brushes that wear out.
  • Lower maintenance requirements.
  • Reduced electromagnetic interference (EMI).
• AC Powered: Operates on a three-phase AC power supply, likely 230VAC or 480VAC depending on the region.
• Frame Size: The “090B” in the code suggests a specific frame size within the MHD series, likely indicating a larger motor frame compared to the MHD041B we discussed earlier. This translates to potentially higher power output and torque.
• Power Output: Exact power rating is difficult to determine without a datasheet, but MHD090B models typically range from 2.2 kW to 7.5 kW (3 hp to 10 hp).
• Cooling Method: The “NG0” might indicate a self-ventilated cooling system, where the motor utilizes an internal fan to circulate air for heat dissipation. This allows for operation in environments with moderate ambient temperatures.
• Flange Mounting: The motor likely has a flanged design for easy integration into industrial machinery.
• IP Enclosure Rating: The “UN” at the end suggests the motor has an IP65 enclosure rating, signifying protection against dust ingress and water jets. This makes it suitable for harsh industrial environments.

Applications:

The REXROTH MHD090B-058-NG0-UN is suitable for various industrial applications demanding robust and efficient motor performance, including:

• Machine tools: Driving spindles and feed axes in CNC machines and machining centers, particularly for larger or more powerful machines.
• Material handling equipment: Powering conveyors, elevators, and other equipment handling heavy loads.
• Pumps and fans: Operating high-performance pumps and fans in industrial processes.
• Textile machinery: Driving weaving and knitting machines in textile production.
• Food and beverage processing: Powering mixers, grinders, and other heavy-duty equipment in food and beverage production.
