Graded selection of three square housings
The 40W BLDC Square Gear Motor comes with three square frame sizes of 60/70/80mm. With the same 40W power rating, the smaller frames fit compact installation stations, while the large 80mm housing delivers enhanced heat dissipation and gear load capacity, catering to both narrow-space equipment and continuous heavy-load applications.
Wide-range torque output
The torque of the 40W BLDC square geared motor ranges from 0.37 to 8 Nm, representing a 60% increase in maximum torque compared with low-power models of 30W and below. It can handle heavy pushing and lifting loads under high reduction ratio conditions with more abundant power reserve.
Compatible dual wiring solutions
40W BLDC Square Gear Motor. Two wiring configurations are available for the same motor body: 8-wire Hall feedback and 3-wire sensorless, differentiated only by wire harness assemblies. Customers can match it with simple speed regulation or high-precision positioning control systems as needed.

Universal compatibility with 8 voltage grades
Full coverage from 12V low-voltage DC to 310V industrial high voltage. Lithium battery AGVs, low-voltage assembly lines and 220V fixed machine tools require no motor structure replacement, simplifying inventory preparation for multiple product lines.
Full speed regulation base with two original base speeds
40W BLDC Square Gear Motor with two base stator speeds of 2000rpm and 3000rpm, matched with a complete reduction ratio range from 1/3 to 1/200. It can accurately output any target rotating speed without additional reduction stages.
Machine-free interchangeable multi-type output shafts
Optical shafts, keyway shafts, gear shafts and spline shafts are standardized and interchangeable. No secondary processing is required when matching with couplings, gears and chains, which greatly shortens the equipment assembly cycle.

Q:What long-term operation advantages does the 40W 80mm frame have over the 60mm frame?
A:The 80mm housing has larger heat dissipation area and thicker gearbox wall, bringing lower temperature rise under long-term full load, with peak torque up to 8Nm, ideal for 24-hour non-stop heavy conveyors.
Q:Does the 12V low-voltage model require an extra stabilized power supply?
A:The standard 12V model needs stable DC regulated power supply; voltage fluctuation will affect speed stability, so matched DC driver power supply is recommended.
Q:Can we customize wire length and connector types for bulk orders?
A:Custom wire length and terminal connectors are free of charge for mass orders to match the internal wiring space of your equipment.
