Description
Emerson MHM-490-CONS-0000
Technical Specifications: Rated input voltage: 400 VAC Reduction ratio: 490:1 Rated output torque: 490 N·m Rated output speed: 3.2 rpm Feedback device: high-precision resolver Operating temperature: -10 ℃ to 50 ℃ Storage temperature: -40 ℃ to 80 ℃ Protection grade: IP54
Functional Features: Ultra-high reduction ratio provides huge low-speed output torque. Reinforced alloy gear bears heavy impact load. Integrated resolver achieves real-time position feedback. Built-in winding temperature monitoring sensor. Sealed gearbox structure prevents dust and moisture ingress. Low backlash design ensures repeated positioning precision. Supports continuous long-time heavy load operation.
Application Scenarios: Large rotary valve actuator, heavy palletizing rotary mechanism, metallurgical rolling auxiliary actuator, bulk material rotary feeder drive, large crane auxiliary rotation mechanism, heavy-duty test bench rotary drive.
Performance Parameters: Backlash: less than 18 arcmin Vibration resistance: 10 Hz to 150 Hz, 0.5 g Shock resistance: 10 g peak acceleration MTBF value: 152000 hours under rated working condition
Material Composition: Motor shell is cast aluminum alloy with anti-rust coating. Gearbox housing uses thick nodular cast iron. Gear and shaft parts use carburized alloy steel. Motor winding uses high temperature resistant polyimide enameled wire. Output shaft surface adopts quenching and anti-wear treatment. Sealing components use fluorine rubber.
Structural Features: Integrated coaxial servo motor and multi-stage reduction gearbox. Front mounting flange for fixed installation on mechanical frame. Output shaft with keyway for torque transmission. Rear end of motor installs resolver feedback assembly. Cable glands for power cable and feedback cable entry. Heat sink structure on motor housing for heat dissipation.
Working Principle: Servo drive outputs three-phase power to drive servo motor high-speed rotation. Rotary power transmits to multi-stage reduction gear set. The gear set reduces rotating speed and amplifies output torque to drive mechanical load. Resolver collects real-time rotation position and speed and feeds back to servo drive to form closed-loop control. Temperature sensor monitors winding temperature and triggers protection when temperature exceeds threshold.
Installation Requirements: Mount the gear motor via front flange with high-strength bolts. Ensure coaxiality between output shaft and driven equipment. Select shielded high-voltage cable for power wiring. Reserve sufficient space around motor housing for heat dissipation. Fix cable to avoid pulling stress on cable gland.
Precautions for Use: Do not run beyond rated torque limit. Inspect gearbox lubricating oil regularly and replace oil according to maintenance cycle. Wear insulating protective equipment during wiring work. Do not apply axial impact load on output shaft. Stop operation immediately when abnormal vibration or noise appears.
