Core Engineering Features
Space-Saving Parallel Layout: Aligns the motor body parallel to the driven shaft to minimize overall machinery length.
High Efficiency Two-Stage Gearing: Delivers up to 96% mechanical efficiency, reducing energy consumption and thermal heat generation.
Modular Drive Design: Allows rapid combination of various gear ratios, frame sizes, motor power ratings, and flange configurations.
Low Maintenance: Heavy-duty seals and synthetic gear lubricants enable extended maintenance-free operation intervals.
Industrial Ruggedness: IP55 dust and water jet protection allows deployment in harsh washdown or dusty ambient conditions.
Industry Applications
Belt & Roller Conveyors: Controlled speed and steady torque for continuous unit and bulk material handling.
Chain Conveyors & Elevators: High starting torque capability to move heavy, high-friction continuous lines.
Screw Feeders & Dosing Equipment: Precise low-speed torque delivery for volumetric material feeding.
Packaging & Bottling Lines: Smooth, low-vibration power transfer for high-speed automated packaging machinery.
Process Equipment & Agitators: Continuous continuous duty power for liquid mixers, rotary screens, and industrial blenders.
Product Architecture
Three-Phase AC Motor: Available in standard efficiency (IE2/IE3) configurations with continuous duty capability.
Two-Stage Helical Gear Train: Case-hardened gear sets deliver smooth torque transfer, low vibration, and quiet operation (<68 dB).
Parallel Shaft Layout: Offset shaft alignment enables side-by-side mounting along machine frames to minimize total footprint.
Heavy-Duty Housing: High-rigidity cast iron (or lightweight die-cast aluminum for smaller frames) minimizes deflection under load.
Triple-Lip FKM Sealing: Synthetic Viton seals prevent oil leakage and protect internal components against dust and moisture ingress.
Precision Bearing Support: Tapered roller or heavy-duty ball bearings absorb radial and axial forces from sprockets, belts, and couplings.
Shaft Options
Solid Shaft Output: Precision-machined shaft extension with keyway (DIN 6885/1). Ideal for connecting to couplings, belt pulleys, and chain sprockets.
Hollow Shaft Output: Features internal keyway or shrink disc connection. Enables direct mounting onto the driven machine shaft to eliminate external couplings and reduce overall alignment footprint.
Mounting Arrangements
Foot Mounted (B3 / B5)
Rigid base structure for direct mounting to structural steel frames or machinery beds.
Flange Mounted (B14 / B5)
Precision alignment flange for direct mating with machine housings.
Torque Arm Mounted
For shaft-mounted hollow shaft units to absorb reaction torque.
Motor & Electrical Options
Voltage & Frequency Support: Standard configurations include 220/380V, 230/400V, 270/460V, or 380/660V operating at 50 Hz or 60 Hz. Motors accommodate standard international mains variations.
Electromagnetic Brake Options: Optional spring-applied, fail-safe DC brakes for instant stopping, holding loads, or safety-critical positioning. Adjustable brake torque ratings available.
Protection & Duty: Standard IP55 enclosure protection (dust-protected and jet-water resistant) with Class F insulation. IP65 or tropicalized insulation available for aggressive outdoor environments.
Quality Control
Gear Tooth Inspection: Checked on CNC gear measuring centers for pitch, profile deviation, and lead error according to ISO standards.
Housing Alignment: CNC machining centers ensure precise bearing bore concentricity and center distances for optimal gear mesh.
Final Performance Testing: 100% of assembled units undergo full-speed run testing to verify low acoustic emissions (<75 dBA), vibration limits, seal integrity, and electrical winding parameters.
Frequently Asked Questions
Q: How do I select the right gearmotor model for my application?
A: Start by identifying your required output RPM and operating torque. Then select motor power, verify service factor based on operating hours and shock load, and confirm shaft mounting dimensions.
Q: Can you perform model selection based on conveyor design data?
A: Yes. Provide conveyor speed, belt width, drum diameter, total load weight, operating hours, and incline angle, and our application engineers will calculate the required drive package.
Q: What information is needed to obtain a fast quotation?
A: Please specify required motor power (kW), output speed (RPM) or ratio, voltage/frequency, mounting orientation, shaft configuration (solid or hollow), and project quantity.
Q: Can you manufacture custom output shaft dimensions to match existing equipment?
A: Yes. Output shaft diameters, length extensions, keyways, and flange pilots can be customized according to your engineering drawings.
Q: Are these units suitable for VFD (Variable Frequency Drive) speed control?
A: Yes. Standard motors feature Class F insulation and inverter-capable windings suitable for VFD operation across variable speed ranges.
Q: What warranty and quality guarantees are provided?
A: All gearmotors come with an 18-month warranty, ISO9001 quality compliance, and 100% factory load-and-noise test inspection reports prior to dispatch.
