Ningbo Vanguard Technologies Co., Ltd
Compact coaxial drive solutions for controlled speed and higher output torque.
Vanguard supports custom planetary gear motor projects from motor and ratio selection through gearbox component development, prototype validation and production planning. The scope can include magnets, motors, precision gears, carriers, shafts, housings, bearings, feedback devices and complete assemblies.
A successful gearmotor is selected from the output load cycle. Continuous torque, peak events, ratio, efficiency, backlash, bearing loads, lubrication and thermal conditions must be considered as one system.
The motor, sun gear, planet gears, carrier, ring gear and output bearings must be matched to the complete duty cycle.
Motor constant, winding, commutation, input shaft and pinion connection.
Sun, planets, carrier and ring gear selected for ratio, torque, efficiency and life.
Shaft, flange, bearings, sealing, backlash and external radial or axial loads.
These common diameters are enquiry starting points. Final output torque, speed and life depend on the motor, ratio, stage count and load cycle.
For miniature actuators where diameter, mass and power consumption are tightly limited.
A compact drive for instruments, automation and small positioning mechanisms.
A balanced platform for moderate torque, compact packaging and repeatable production.
For equipment requiring a larger motor, robust gearbox interface and configurable feedback.
A medium frame for power tools, pumps and electromechanical equipment.
For higher output torque where gearbox strength, bearings and heat rejection become critical.
A configurable platform for projects needing a specific flange, shaft or load interface.
A larger planetary drive for sustained load and demanding mechanical integration.
Planetary drives are useful where coaxial packaging, reduction and torque density must be combined.
High reduction, compact coaxial packaging and short-duration peak torque can suit cutters, crimpers and powered hand tools.
Wheel drives require gradeability, start torque, shock loading, sealing and battery consumption to be evaluated together.
Valve duty requires reliable start torque, controlled travel, limit sensing and protection against stall or obstruction.
Connect the load, motor, gearbox and manufacturing controls before releasing samples.
Convert output torque, speed, starts, reversals and dwell periods into motor and gearbox requirements.
Balance output speed, torque, efficiency, length, noise and load capacity across the planetary stages.
Review gear material, tooth geometry, carrier stiffness, pins, bearings and lubrication for the target life.
Coordinate motor winding, torque-speed curve, current limit and thermal behavior with gearbox efficiency.
Measure torque, speed, current, temperature, backlash, acoustic noise, efficiency and durability.
Define gear inspection, runout, axial play, grease quantity, assembly torque and end-of-line testing.
Provide these inputs so the gearbox can be sized against real operating and life conditions.
| Input | Information to Provide | Engineering Impact |
|---|---|---|
| Output Duty | Continuous torque and speed, peak torque, peak duration, starts and reversals | Defines motor capacity, ratio, stage loading and thermal margin. |
| Electrical Supply | Voltage range, current limit, driver and feedback interface | Determines motor winding and available input power. |
| Reduction Ratio | Preferred output speed, motor speed range and acceptable stage count | Controls torque multiplication, efficiency, length and inertia. |
| Precision | Backlash, positioning accuracy, repeatability and torsional stiffness targets | Influences tooth geometry, bearing arrangement and production tolerance. |
| Shaft Loads | Radial load, axial load, overhung distance, shock and mounting orientation | Defines output shaft, bearings and housing support. |
| Life & Noise | Operating hours, cycle count, acoustic limit and permitted wear | Drives gear material, heat treatment, lubrication and quality level. |
| Environment | Ambient temperature, dust, moisture, chemicals, corrosion and sealing | Influences materials, grease, seals and validation tests. |
| Program Plan | Prototype quantity, acceptance criteria, annual volume and dates | Aligns tooling, inspection, sourcing and production ramp. |
Ideal output relationship: nout = nmotor / i, and Tout ≈ Tmotor × i × η. Use measured or validated stage efficiency and observe both continuous and peak gearbox limits.

Contact VanguardIt combines an electric motor with a coaxial planetary gearbox. A sun gear drives planet gears supported by a carrier inside a ring gear, producing speed reduction and torque multiplication in a compact package.
Start with the required output speed and torque, then account for motor speed, stage efficiency, duty cycle and peak events. Very high ratios can increase length, losses, backlash and reflected inertia.
Only approximately. Output torque is motor torque multiplied by the ratio and gearbox efficiency. The result must remain below allowable continuous and peak limits for the gears, carrier, shaft and bearings.
Common contributors include gear profile error, runout, backlash variation, bearing condition, carrier stiffness, lubrication, motor commutation and resonance in the mounted system.
The project scope can include Hall sensors, encoders, brakes, wiring, connectors and customized mounting or output interfaces. Integration is confirmed after reviewing space and control requirements.
Provide voltage, output torque and speed, peak events, duty cycle, ratio preference, package drawing, shaft loads, backlash, noise, life, environment and annual quantity.
