The Omni+™ motors were designed to have a large through hole which result in a large ratio of their ID to OD. This extra space at the center of the motor can allow cables to be routed through a robot joint or can even provide space for components (such as a brake) to minimize the axial length of an assembly. The ID to OD ratios for the Omni+ motors are as follows:
- 60mm: 51.7%
- 70mm: 54.3%
- 100mm: 60%
- 130mm: 60%
