Micro Gear Motors¶

Product Overview¶

SigGear develops miniature gear-motor and compact transmission solutions for robotics, medical devices, laboratory automation, precision instruments and compact industrial mechanisms.

The product range is based on miniature planetary gear reducers and application-specific motor integration. Available gearbox diameters and final motor configurations depend on the required torque, speed, voltage, installation envelope and production quantity.

Product Scope¶

Miniature planetary gear motors
Compact planetary reduction motors
Motor and gearbox integration based on the 8–42 mm planetary reducer range
Custom output shafts, flanges and mounting interfaces
Optional encoder, brake, cable and connector integration after engineering review
Application-specific OEM and ODM development

Typical Applications¶

Micro robotics
Robot grippers and end effectors
Medical and dental devices
Laboratory automation
Optical adjustment mechanisms
Precision instruments
Smart hardware
Miniature pumps and valves
Compact automation mechanisms

Motor Integration¶

Depending on the selected gearbox and project requirements, SigGear can evaluate integration with:

Brushed DC motors
Brushless DC motors
Stepper motors
Servo motors
Customer-specified motors

Motor compatibility is confirmed according to input speed, power, shaft interface, duty cycle, thermal conditions and required output performance.

Start Even If the Ratio Is Not Defined¶

A project can start from the mechanism rather than a complete gearbox specification. If the reduction ratio is unknown, provide the motor speed and desired output speed if available. If the output torque is unknown, send the load, mechanism geometry or a sketch so the engineering team can identify what must be calculated or tested.

Engineering Documents¶

Public model pages contain the reviewed data currently released for each gearbox platform. The 32P already has a public Engineering Pack with a datasheet, mechanical-interface reference, motor-integration guide and simplified STEP model.

Configuration-specific drawings, CAD, noise information and service-life information are supplied according to the selected model and application review.
