Flat BLDC Motors and Joint Drives¶

Product Overview¶

SigGear supplies flat motor and integrated joint-drive solutions for robots, exoskeletons and compact automation systems.

The standard flat joint-drive families are distinguished by their transmission structure:

SigGear-Horse: planetary transmission core
SigGear-Tiger: cycloidal-pinwheel transmission core

These products are intended for applications that require a short axial package and integrated mechanical and electrical functions. Final motor, reducer, driver, encoder and communication configurations are confirmed for the selected model and quotation.

Standard Product Families¶

Product family	Transmission structure	Catalog configuration
SigGear-Horse	Planetary	Driver-equipped configurations and encoder support are available by model
SigGear-Tiger	Cycloidal pinwheel	Driver-equipped configurations and single- or double-magnetic-encoder options are available by model

Typical Applications¶

Humanoid robot joints
Exoskeleton joints
Quadruped robot joints
Robotic arms
Rehabilitation equipment
Compact rotary axes
Research and education platforms

Integration Options¶

Depending on the selected model and project requirements, available configurations may include:

Motor and transmission assembly
Integrated driver
Magnetic encoder
CAN communication
RS485 or other project-specific communication interfaces
Custom cables and connectors
Custom mounting and output interfaces
Customer branding and labeling

Driver, encoder, protocol and closed-loop-control functions must be confirmed in the quotation and technical agreement. They must not be assumed from the product-family name alone.

Selection Information Required¶

Please provide:

Application and joint position
Required continuous and peak torque
Required output speed and motion cycle
Operating voltage
Maximum outer diameter and thickness
Weight target
Radial and axial load conditions
Driver and encoder requirements
Communication interface
Prototype quantity and estimated annual volume

Motor and Transmission Integration¶

For projects that start from a motor, target output motion or installation envelope rather than a fixed joint-drive model, use the motor + gearbox integration path.

Motor + Gearbox Integration Engineering

Custom Robot Joint Development¶

For robotics teams whose torque, speed, size, motor, encoder, driver or mounting requirements do not match an existing joint-drive model, use the custom robot joint development path.
