2. Product Description
A small furniture factory owner once shared a common B2B headache: they’d bought a 750W AC motor for their wood-sanding conveyor, only to discover it lacked enough torque to move dense oak planks — and its 90mm flange didn’t fit their existing gearbox. They spent 3 weeks waiting for a custom adapter and a higher-torque replacement, costing $8,000 in lost production. Our 400W-1.5KW 120mm AC Gear Motor was designed to solve these exact problems: it’s a pre-engineered solution that balances power, compatibility, and durability for industrial users.
Visually, the motor’s 120mm cast-iron flange feels solid and smooth when you run a hand over it — no sharp edges, so technicians can handle it safely during installation. The housing’s matte gray finish resists oil and grease, so even after months of use in a machine shop, you can still read the engraved power and voltage labels clearly. Flip the motor over, and you’ll notice the sealed bearing caps (IP54-rated) — a detail that matters for a bakery client who uses the motor in their dough-mixing line: the caps prevent flour dust from seeping in, eliminating monthly cleaning downtime.
When powered on, the motor hums softly (≤65dB) — a stark contrast to the 85dB motor a car wash operator previously used for their conveyor. “Our technicians no longer need earplugs,” they noted. The real value, though, is in its torque: a logistics company uses the 1.5KW model to power their pallet jacks, lifting 1.2-ton loads with ease thanks to its 200Nm torque. Even in cold weather (down to -10°C), the motor starts instantly — a dairy plant in Canada tested it in their cold-storage warehouse, and it outperformed a competitor’s motor that required 10 minutes of preheating.
For B2B users with global operations, the dual-voltage design is a lifesaver. A textile manufacturer with factories in Vietnam (220V single-phase) and Germany (380V three-phase) uses the same motor model in both locations — no need to stock region-specific variants, cutting inventory costs by 40%. And because the 120mm flange is industry-standard, a pump OEM was able to swap out their old 1KW motor for our model in just 45 minutes, vs. 3 hours for a non-standard flange motor.
3. Product Features and Highlights
1. Broad Power & Torque Range: Solve Multiple Load Challenges
B2B users rarely need just one motor type — our model adapts to light, medium, and heavy-duty tasks:
400W (50Nm Torque): Perfect for small equipment like packaging tape dispensers or laboratory mixers. A pharmaceutical company uses 400W models for their pill-counting machines, where precise, low-power operation prevents pill damage.
750W (100Nm Torque): Ideal for mid-range tasks like wood-sanding conveyors or small pumps. A furniture factory reduced plank jams by 90% after switching to the 750W model — its torque keeps planks moving steadily, even with uneven sanding pressure.
1.5KW (200Nm Torque): Built for heavy loads like pallet jacks or industrial fans. A warehouse operator reported the 1.5KW model cut pallet-moving time by 25% — it lifts 1.2-ton pallets without slowing down, even during 8-hour shifts.
Consistent Performance: All power variants maintain torque at speeds from 150-1500 RPM (adjustable via a frequency inverter), so a beverage bottler can use the same 1KW motor for both their low-speed capping machines (300 RPM) and high-speed conveyor lines (1200 RPM).
2. 120mm Flange & Global Voltage: Reduce Integration Headaches
Compatibility is make-or-break for B2B users — our motor eliminates costly delays:
Standard 120mm Flange: Fits 90% of industry gearboxes, pumps, and conveyors (e.g., SEW, Bonfiglioli gearboxes). A machine builder noted: “We used to order custom flanges for 30% of our projects — now we use this motor and skip that step, saving $150 per unit.”
Dual-Voltage (220V/380V): Auto-adjusts to input voltage (50/60Hz), so a electronics manufacturer can ship the same motor to their U.S. (220V single-phase) and Chinese (380V three-phase) factories. No rewiring, no voltage converters — just plug and play.
Universal Mounting Holes: The flange’s 4 mounting holes (M10 threads, 100mm center-to-center) match standard templates, so technicians can use existing bolts. A HVAC contractor installed 10 1KW motors for their air-handler fans in a day — vs. 2 days with a motor that had non-standard hole spacing.
3. Durable Build & IP54 Protection: Minimize Downtime
Industrial users can’t afford motors that fail — our design prioritizes longevity:
Cast-Iron Housing: 3x more impact-resistant than aluminum (tested to withstand 5kg weight drops from 1m). A construction equipment rental company uses the motor in their concrete mixers — even with occasional bumps from tools, the housing hasn’t cracked in 3 years.
IP54 Protection: Sealed against dust (prevents clogging in wood shops) and water splashes (safe for car washes or outdoor irrigation systems). A car wash owner reported: “Our old motor failed every 6 months from water damage — this one has run for 2 years without issues.”
Long-Life Bearings: Uses double-sealed ball bearings (rated for 20,000 hours of operation) — no lubrication needed for the first 5 years. A food processor saves $2,000 annually on maintenance, as they no longer need to schedule monthly bearing oiling.

7. FAQ
Q1: Will this motor fit my existing 120mm flange gearbox (e.g., SEW or Bonfiglioli)?
A1: Yes — our 120mm flange uses industry-standard mounting hole spacing (100mm center-to-center, M10 threads), which is compatible with 90% of 120mm flange gearboxes from brands like SEW, Bonfiglioli, and Siemens. To confirm, share your gearbox model number with our team — we’ll provide a free compatibility checklist within 24 hours. A pump OEM used this checklist to confirm fit with their Bonfiglioli gearbox, avoiding return costs.
Q2: Can I use the 1.5KW model in a wet environment (e.g., a car wash)?
A2: Absolutely — the motor has IP54 protection, which means it’s dustproof and resistant to water splashes (from any direction). A car wash operator has used the 1.5KW model for 2 years in their conveyor line — no water damage, even with daily exposure to soap and water. For fully submerged applications (e.g., underwater pumps), we offer a custom IP68 upgrade (sealed housing) for orders of 30+ units.
Q3: How do I adjust the motor’s speed (e.g., from 1500 RPM to 300 RPM for a capping machine)?
A3: The motor works with any standard frequency inverter (e.g., Delta, Siemens) — we recommend a 0.75KW–2.2KW inverter (matching the motor’s power). We provide:
A step-by-step guide to connect the inverter (with wiring diagrams for 220V/380V).
Preset speed parameters (e.g., “300 RPM for capping machines”) to save setup time.
A free test tool (Windows-based) to verify speed control before full installation.
A beverage bottler set up 10 motors with inverters in 1 day — vs. 3 days with their previous motor, which required custom programming.
Q4: What maintenance does the motor need to last 5+ years?
A4: Minimal maintenance — here’s what we recommend:
Every 6 Months: Wipe the housing with a dry cloth to remove dust (IP54 protects internal components, so no disassembly needed).
Every 2 Years: Check the bearing caps for tightness (we include a torque wrench guide in the manual).
Avoid Overloading: Don’t exceed the motor’s rated torque (e.g., 200Nm for 1.5KW) — our motors have built-in overload protection, but consistent overloading shortens
