1. Product Introduction
Compact 90mm Design for Space-Constrained B2B Setups: The slim 90mm flange fits tight spaces in small machinery (e.g., desktop labeling machines, mini conveyors) — critical for workshops or production lines where floor/bench space is limited.
Flexible Power Range for Light-to-Medium Tasks: Covers 40W (ideal for precision tools like 3D printer feeders) to 180W (suited for small-scale material handling, such as 5kg-capacity belt conveyors), eliminating the need to stock multiple motor models.
Global Voltage Compatibility: Works with 110V/220V single-phase (50/60Hz) — no voltage converters needed for North American (110V) or European/Asian (220V) factories, simplifying cross-border procurement.
Low Noise & High Torque: Operates at ≤55dB (quieter than a conversation) for noise-sensitive environments (e.g., electronics assembly), while delivering 15-80Nm torque (depending on power) to handle consistent loads without stalling.
Durable Build for 24/7 Operation: Features aluminum alloy housing (lightweight yet corrosion-resistant) and IP54 protection (dustproof, splash-proof), ensuring reliability in settings like food packaging or lab equipment.
2. Product Description
A small electronics manufacturer once faced a frustrating problem: their 3D printer assembly line relied on a generic 60W motor that was too bulky (120mm flange) to fit their compact feeder units. They had to redesign the feeder’s frame — a 4-week delay that cost $3,000 in lost orders. Our 40W-180W 90mm AC Gear Motor was built to solve this exact pain point: it’s a space-efficient, power-flexible solution tailored for B2B users who need performance without sacrificing room.
Visually, the motor’s 90mm aluminum flange feels smooth and lightweight (40W model weighs just 4.5kg) — technicians can easily mount it with one hand, even in tight spots like under a labeling machine’s conveyor belt. The housing’s anodized silver finish resists fingerprints and oil, so after months of use in a mechanic’s workshop, it still looks clean enough for customer demos. Flip it over, and you’ll notice the recessed wiring terminals — a detail that matters for a pharmaceutical lab using the 40W model: the terminals prevent dust or liquid from seeping in, meeting strict hygiene standards.
When powered on, the motor’s hum is barely noticeable (≤55dB) — a game-changer for a jewelry manufacturer that uses the 75W model in their bead-sorting machines. “Our workers no longer need to shout over equipment noise,” their production manager noted. The real value lies in its torque consistency: a bakery uses the 180W model to power their mini dough-kneading rollers, which require steady 60Nm torque to avoid uneven dough. Unlike their old motor (which stalled 2-3 times per shift), our motor runs 8-hour shifts without interruptions.
For B2B users with global clients, the 110V/220V compatibility is a lifesaver. A packaging machine OEM sells their equipment to both U.S. (110V) and German (220V) bakeries — they use the same 90mm motor in all units, cutting inventory costs by 30% (no need to stock region-specific motors). And because the 90mm flange is a common industry size, a 3D printer manufacturer swapped out their old 120mm motor for our 40W model in 20 minutes — no frame redesign required.
3. Product Features and Highlights
1. Space-Saving 90mm Flange: Solve Compact Machinery Challenges
B2B users in industries like electronics or small-scale manufacturing often struggle with bulky motors that disrupt equipment design. Our 90mm flange eliminates this issue:
Standardized Fit for Small Equipment: Compatible with 85% of compact machinery (e.g., desktop labeling machines, mini conveyors, 3D printer extruders) from brands like Brother or Epson. A 3D printer OEM reported: “We used to modify our feeder frames to fit 120mm motors — now we drop in this 90mm model, saving 2 hours per unit in assembly.”
Lightweight Aluminum Construction: The 40W model weighs 4.5kg, the 180W model 8.2kg — 30% lighter than cast-iron motors of the same power. This makes it easy to mount on overhead or vertical surfaces (e.g., wall-mounted conveyor belts) without extra support brackets.
Low Profile Design: The flange’s thickness is just 15mm, so it fits in gaps as narrow as 20mm (e.g., between two rollers in a dough mixer). A bakery noted: “Our old motor stuck out 30mm, blocking access to the mixer’s control panel — this one sits flush, making maintenance faster.”
2. Flexible Power & Torque: Adapt to Light-to-Medium Tasks
One motor model replaces multiple SKUs, simplifying inventory for B2B users:
40W (15-25Nm Torque): Perfect for precision tasks like 3D printer filament feeding, small pump operation, or lab stirrers. A pharmaceutical lab uses 40W models in their liquid-mixing stations — the low power avoids overheating sensitive solutions, while 20Nm torque ensures consistent stirring.
100W (35-50Nm Torque): Ideal for mid-range applications like desktop labeling machines or 5kg-capacity belt conveyors. A shipping company uses 100W motors in their parcel-sorting conveyors — the torque handles small boxes without slowing down, cutting sorting time by 15%.
180W (60-80Nm Torque): Suited for heavier light-duty tasks like mini dough kneaders or small woodworking lathes. A furniture workshop uses 180W models in their pen-turning lathes — the motor maintains speed even with dense hardwood, reducing product defects by 20%.
3. Durability & Safety for Industrial Environments
B2B users can’t afford downtime from fragile motors — our design prioritizes longevity:
IP54 Protection: Sealed against dust (prevents clogging in wood shops) and water splashes (safe for food packaging lines where cleaning with water is common). A snack factory uses 120W models in their chip-packaging machines — no motor failures from crumbs or cleaning sprays in 18 months.
Class B Insulation: Safe for operating temperatures up to 130°C, so it works in warm environments like plastic injection molding workshops. A plastic manufacturer runs 180W motors next to 80°C molding machines — no overheating issues, even during 12-hour shifts.
Long-Life Bearings: Uses double-sealed ball bearings rated for 15,000 hours (≈2 years of 24/7 use) — no lubrication needed for the first 3 years. A hardware store saved $1,200 annually on maintenance, as they no longer need to service motor bearings monthly.

5. Application Scenarios
Electronics & 3D Printing
3D Printer Extruders: The 40W (20Nm) model feeds filament at a steady 50 RPM, avoiding jams that ruin prints. A 3D printing service used to have 8% of orders fail due to motor stalling — with our motor, failure rates dropped to 1%.
Circuit Board Conveyors: The 75W (35Nm) model powers mini conveyors that move circuit boards through soldering stations. An electronics manufacturer noted: “The motor’s low noise (≤55dB) keeps our soldering techs focused, and its small size fits under the station’s hood.”
Food & Beverage
Mini Dough Kneaders: The 180W (70Nm) model runs dough rollers for small bakeries, maintaining consistent pressure to avoid uneven dough. A family-owned bakery cut dough preparation time by 20% — no more stopping to adjust the motor or re-knead lumpy dough.
Snack Packaging Lines: The 120W (50Nm) model drives small packaging rollers (IP54 protection resists crumbs and cleaning sprays). A chip manufacturer reported: “Our old motor needed replacement every 6 months — this one has run for 18 months without issues.”
Lab & Pharmaceutical
Liquid Stirrers: The 40W (15Nm) model stirs sensitive pharmaceutical solutions at 100 RPM, avoiding overheating (Class B insulation handles lab temperature fluctuations). A drug lab uses 10 units — the motor’s precision ensures consistent mixing, critical for batch quality.
Sample Conveyors: The 75W (30Nm) model moves test samples through analysis machines. A research facility appreciated the motor’s compact size: “It fits in our lab’s under-counter conveyors, freeing up bench space for other equipment.”
Small-Scale Manufacturing
Jewelry Bead Sorters: The 100W (45Nm) model sorts beads at 300 RPM — low noise keeps workers comfortable, and torque handles mixed bead weights. A jewelry maker said: “We used to have to turn off the sorter periodically because of noise — now it runs all day.”
Pen-Turning Lathes: The 180W (80Nm) model powers small lathes for wood or plastic pens. A craft supply manufacturer reduced defects by 25% — the motor maintains speed even with dense materials, ensuring smooth pen barrels.
