Key Product Features

01/

Integrated Fail-Safe Brake: Built directly into the motor enclosure, eliminating external alignment issues and saving axial space.

02/

Space-Saving Right-Angle Drive: 90-degree shaft configuration fits tightly against machine frames and narrow conveyor walls.

03/

High Overload & Shock Resistance: Hardened worm gear components withstand high peak starting loads without tooth breakage.

04/

Flexible Shafting Options: Available with solid single/double extensions, hollow shafts with keyways, or shrink disc clamping sets.

05/

Maintenance-Free Synthetic Lubrication: Pre-filled with premium grade ISO VG 320 synthetic oil, eliminating oil changes under normal operating conditions.

06/

Modular Mounting Configuration: Universal housing design allows foot, output flange, or shaft mounting with a torque arm.

Application Areas

Conveyor Systems: Inclined belt drives, pallet conveyors, and indexers requiring precise stopping without back-sliding.
Material Handling: Automated storage and retrieval systems, sorting tables, and transfer cars.
Packaging & Labeling Machinery: High-precision feeding systems, rotary index tables, and sealing equipment.

Automated Gate & Door Actuators: Low-speed drives requiring reliable holding torque when de-energized.
Processing Machinery: Food mixers, agitators, and chemical processing rigs needing washdown-ready IP65 protection.
Lifting & Hoisting Equipment: Small hoists, winches, and overhead positioning systems requiring fail-safe dual braking redundancy.

Integrated Drive Architecture

The assembly combines three core functional modules arranged linearly for maximum mechanical efficiency:

Three-Phase AC Motor: Provides primary input power with low noise and low vibration. Optimized for continuous duty and VFD operation.

Worm Gearbox: High-strength hardened worm shaft meshing with a synthetic bronze alloy worm wheel. Delivers smooth 90-degree transmission with space-saving right-angle geometry.

Electromagnetic Brake: DC spring-applied fail-safe brake mounted directly to the non-drive end of the motor. Engages instantly when power is cut, providing controlled stopping and holding without back-driving.

Selection Steps

Determine Motion Requirements: Confirm output speed (rpm), load torque (Nm), and machine duty cycle.
Select Ratio & Frame Size: Match reduction ratio and efficiency to establish required motor power.

Verify Thermal & Duty Limits: Check thermal power capacity and start/stop frequency per hour.
Size the Brake: Account for total load inertia, stopping time requirements, and self-locking characteristics of the worm set.
Confirm Mechanical Interface: Verify mounting position, shaft diameter, keyway dimensions, and center distance.

Customization Matrix

Mechanical

Custom shaft diameters/lengths, stainless steel shafts, dual-output shafts, special oil seals (Viton/NBR).

Electrical

Special voltages (110V - 690V), PTC thermistors, forced cooling fans, encoder integration.

Environmental

Low-temperature grease (down to -40°C), high-ambient synthetic lube, IP66/IP67 washdown protection.

Export Packaging & Global Logistics

Protective Packaging: Heavy-duty, ISPM-15 compliant export plywood cases or reinforced corrugated boxes with internal shock-absorbing foam.

Corrosion Protection: VCI anti-rust wrapping prevents moisture damage during ocean freight transit.

Documentation Included: Comprehensive packing list, CE Certificate of Conformity, Commercial Invoice, Maintenance & Installation Manual, and factory test reports on request.

Frequently Asked Questions

Q: Can a worm geared motor rely solely on gear self-locking for load holding?

A: No. While high-ratio worm gears (ratio 30:1 or higher) offer static resistance, external vibrations or dynamic forces can cause slow creep. A dedicated electromagnetic brake is essential for safe static and dynamic holding.

Q: Are replacement models dimensionally interchangeable with standard European models?

A: Yes, our gearboxes adhere to standard international dimensions, allowing 100% bolt-on compatibility with standard shafts, flanges, and center distances.

Q: What is the typical lead time for OEM custom configurations?

A: Standard catalog configurations ship within 5–7 business days. Custom shafting, special voltages, or modified flanges typically ship in 2–3 weeks.

Q: Can the electromagnetic brake be released manually during a power failure?

A: Yes, an optional hand-release lever can be integrated onto the brake assembly to disengage the brake manually in emergency situations.
