[New Product] High-speed, high-torque specification! "Intermediate Shaft" for EV Motor Evaluation Equipment

By installing an intermediate shaft between the test motor and measuring instruments such as torque meters, we achieve machine protection and load reduction during abnormal conditions. We also plan to exhibit at trade shows!

**Overview** There are two models with rotational speeds of 20,000 RPM and 30,000 RPM. The model that achieves 30,000 RPM uses ceramic bearings and has been developed to maintain high torque. The rotation direction is bi-directional, and it has passed environmental tests from -20 degrees to a maximum of 80 degrees. **Role** - To protect the dynamo motor and measuring instruments during abnormal conditions of the test motor by installing an intermediate shaft between the test motor and measuring instruments. - To accurately indicate the stress transmitted from the test motor to the measuring instruments at the shaft center. - To reduce the impact of environmental temperature from the test motor on the measuring instruments. **Features** - Rotation: 20,000 to 30,000 RPM - Torque: 500 Nm - Runout accuracy: Radial and axial direction under 3 μm - Intermediate shaft shape: Shaft center height, shaft length, shaft diameter, other modifications possible - Delivery time: Shortest possible response (Note: Rotation, torque, and runout accuracy are based on the production of sample spindles.)
