The 600W Brushed DC Motor With Gearbox is equipped with a large 120×120mm square frame. The integrally cast housing provides large structural reference surfaces and superior rigidity for stable positioning under continuous dynamic loads. Optimized electromechanical matching delivers wide linear operating range and consistent torque output. Complying with universal 120-frame mounting standards, it supports direct power upgrade for heavy-duty automation equipment. Widely used in heavy conveyor lines, large lifting platforms, heavy-load transfer mechanisms, auxiliary engineering equipment and heavy warehouse material handling systems.

120×120 Large Cast Square Frame with Stable Structural Reference
The large integrated square housing features broad bearing surfaces with strong torsion and deformation resistance. It avoids structural micro-shift under long dynamic loads and maintains consistent transmission coaxial accuracy.
Linear Power Output over Wide Operating Range
Optimized armature and magnetic circuit design ensures steady torque across a broad speed band. Torque drops gently under variable loads, ideal for reciprocating motion with changing load.
Unified 120-frame External Mounting Standard
Flange outline, mounting holes and shaft dimensions follow industry norms. Direct in-situ replacement with competitive 120-frame motors is available without frame rework.

Strong Deformation Resistance under Heavy Mounting Load
Large four-point supporting surfaces distribute force evenly, preventing housing distortion caused by concentrated load and reducing eccentric wear on couplings, lead screws and other transmission components.
Ideal for Integrated Heavy-duty Modules with Multiple Motors
Regular right-angle shape without curved protrusions facilitates dense arrangement inside heavy frames and simplifies the design of integrated heavy-load drive modules.
Wide Working Condition Adaptability with Multi-angle Mounting Support
Reliable fixing for horizontal, vertical and inclined installation. The large frame structure resists loosening to meet diverse layout requirements of heavy machinery.

Q: What structural advantages does the 120×120 large frame motor have over 90-frame models?
A: Larger frame cross-section greatly improves housing rigidity. It withstands higher continuous and impact loads and is less prone to coaxial offset under prolonged heavy-duty operation.
Q: Will long-term heavy-load operation at large tilt angle affect gearbox lubrication?
A: Long-term extreme tilt under heavy load is not recommended. If such working condition is unavoidable, shorten inspection cycles to monitor grease distribution.
Q: Is this motor suitable for equipment with frequent impact loads?
A: The rigid 120 frame offers good shock resistance. Nevertheless, a buffer mechanism is recommended for continuous cyclic impact to extend service life.
