SEW-EURODRIVE Right-Angle Helical-Bevel Gearmotor assembly engineered for heavy-duty industrial applications requiring high torque and variable or precise speed control.

• The breakdown below outlines the full technical specifications decoded directly from each part of your model string:
  Gearbox ConfigurationWA51: Mounting position/housing designation, typically indicating a specific shaft arrangement or mounting flange configuration tailored to the machine layout.
• MOD K97: Represents a Size 97 Right-Angle Helical-Bevel Gear Unit. Helical-bevel gears are highly efficient (typically over 90%), offering wear-free lifetime gearing capable of handling high mechanical radial loads.
  
• Motor & Operating SpecsDRE160MC4: The high-efficiency standard AC motor.160M: Defines the frame size.
• C4: Represents a 4-pole motor configured for basic operation.
• Power Output: 15 HP (11 kW) continuous duty rating.
• Electrical: 3-Phase, operating at 230/460V AC.
• Speed Profile: Designed to step down an input speed of 1780 RPM down to an output speed of 46 RPM, establishing a gear reduction ratio of roughly 38.7:1
  
• Integrated Components & FeaturesBE20: An integrated, heavy-duty mechanical safety brake with a nominal braking torque configuration suited for keeping or stopping substantial loads.
• HR: Equipped with a manual brake release mechanism (hand lever), allowing operators to manually disengage the brake for maintenance, positioning, or power failures.
• TH: Features integrated thermal protection (typically a PT100 or thermistor element) embedded in the motor windings to monitor temperature and prevent burnout.
• EG7C: An added high-resolution incremental rotary encoder mounted to the motor shaft. This component tracks motor speed and position feedback, making this specific unit optimized for precise closed-loop automation control via a Variable Frequency Drive (VFD)
  

The SEW-EURODRIVE Gear Motor WA51 Model K97 DRE160MC4BE20HR/TH/EG7C is ideal for demanding industrial applications requiring high torque and precise speed control. It operates within a speed range from 1780 RPM input to 46 RPM output, achieved through a 38.7:1 gear reduction ratio. The helical-bevel gear unit is efficient, typically over 90%, allowing for minimal wear and long-lasting performance. This gear motor features a DRE160MC4 motor, rated at 15 HP (11 kW) for continuous duty. It is compatible with three-phase power systems, functioning at 230/460V AC. The motor's frame size is 160M, and it uses a 4-pole configuration. It's housed in a TEFC (Totally Enclosed Fan Cooled) enclosure, which ensures protection against external conditions. Additional features include an integrated BE20 safety brake for reliable load retention, a manual brake release for operational flexibility, and thermal protection to prevent over-temperature conditions. An EG7C high-resolution rotary encoder provides precise speed and position feedback, supporting closed-loop control scenarios when used with a Variable Frequency Drive (VFD). This robust assembly is well-suited for applications necessitating high precision and reliability.
